Description

System and method for network management

technical field

The present invention relates to a communication technology, in particular to a network management system and method. the

Background technique

With the development of modern computer networks, computing networks have become more complex, especially the current integration of communication data networks and computer networks, making network management more complex. The failure or failure of the network due to various reasons will bring a lot of inconvenience to people's life, so it is very important to maintain the normal operation of the network, which requires proper management of the network. Currently, the most widely used network management protocol in computer networks is the Simple Network Management Protocol (SNMP). In this protocol, a manager-agent management model is defined. The manager can be a PC or a workstation, etc., and is generally located at or near the backbone of the network. It is responsible for issuing instructions for management operations and receiving information from agents. . An agent is one or more processes running inside the managed device, which converts the command request from the manager into an instruction recognizable by the device, completes the management command or returns the required management information. Now there are mainly two solutions for the realization of the network management system, one is the traditional platform-related centralized management solution based on the C/S (Client/Server, client/server) structure, and the other is the cross-platform based Distributed management scheme of C/S structure. The two management schemes are described below. the

1. Management plan related to the platform

Platform-related management solutions started in the early days of network development. At that time, network management platforms were specially developed by various network equipment manufacturers. Most of the equipment in a network was provided by one manufacturer. The implementation of network management platforms focused on performance and In terms of functions, most of them are written in C/C++ and do not require high platform portability. This kind of network management generally adopts the C/S centralized management method, and the server side completes all network management functions (such as performance management, configuration management, security management, fault management, etc.), these functions are placed in a process, inside the process It is processed in a multi-threaded manner. Specifically, as shown in FIG. 1 , the user terminal sends a management message to the agent in the managed network element through the server, and the agent in the managed network element implements the management of the managed network element. Those who are familiar with network management technology know that this structure can easily lead to a large process load, which greatly reduces the performance and stability of the network management system. the

Specifically, the disadvantages of this management scheme are as follows:

1) Platform dependency. The network management system is strongly related to the equipment of a specific manufacturer, that is to say, the network management system of each manufacturer can only manage the communication equipment of its own manufacturer. The main reason is that the graphics display technology and system function calls on different platforms are incompatible with each other. If cross-platform implementation is required, two different systems must be developed, which increases the development cost and cycle time. the

2) Low performance. This method will lead to excessive system process load, especially when the managed network elements send alarm events to the network management in a centralized manner or when the network management centrally collects data from the managed network elements, due to the need to occupy a large amount of network bandwidth, It consumes network resources, etc., which greatly reduces the performance of the network management system, and even causes the system to crash. the

3) Poor flexibility. Since the user terminal and the server are hard-coded, every time there is a change in demand, the code must be modified, compiled and connected to achieve the change in demand, which cannot meet various flexible and personalized needs. The flexibility mentioned includes flexible customization of interface, flexible selection of modules, flexibility of networking mode, diversity of forms of monitoring objects and management objects, and the like. Personalization is not only related to the special application of the user's industry, but also related to the user's usage habits and management methods. the

4) Poor reliability. When the server single point of failure, the entire network management system cannot be used. the

5) The installation and maintenance costs of the system are high. This method requires the installation of a user terminal program before it can be used, and if the user wants to perform network management on multiple machines, especially on a remote machine, multiple sets of user terminal software must be installed at the same time. In addition, when the user terminal software has a problem or needs to be upgraded, all user terminal software needs to be updated, which brings a lot of overhead to system maintenance. the

6) It cannot meet the cross-platform requirements of user terminals. Generally speaking, operating systems of user terminals are different, and corresponding user terminal programs are also different. However, it is also unrealistic to design a user terminal program for each operating system. Requiring customers to give up existing operating systems to buy a new operating system will make customers pay a lot. the

2. Cross-platform management plan

With the emergence of more communication providers, the sources of equipment in the communication network tend to be diversified; at the same time, the network management requirements are becoming more and more complex and the CORBA (Common Object Request Broker Architecture, Common Object Request Broker Architecture) technology is gradually maturing, resulting in a A distributed network management system implemented with CORBA technology. the

As shown in Figure 2, compared to the network management structure of the above-mentioned single process, this distributed network management system is still a C/S structure, but the server side is divided into different CORBA objects according to functions, and these CORBA objects can be distributed. run on a different server. This solution solves the problem of distributed network management, improves network performance and flexibility to a certain extent, but it is still a traditional manager in terms of a specific management function point (such as fault management). - Proxy mode, as shown in FIG. 3 , that is, the administrator manages the managed network elements through a proxy. There are still many problems in this management mode. Specifically, this management scheme has the following disadvantages:

1) Low performance. In this way, all management tasks are concentrated on the manager side (the CORBA object on the server), and there are still excessive single-point loads and single-point communication bottlenecks. Especially when the managed network elements centrally send alarm events to the network management or when the network management collects data from the managed network elements in a centralized manner, since a large amount of network bandwidth and network resources are required to be consumed, network management is greatly reduced. system performance. the

2) Poor reliability. In this way, there is no good reliability guarantee mechanism. When a specific CORBA object on the server side fails or malfunctions, its corresponding service function cannot be provided. the

3) The interface display flexibility is poor. Since the user terminal is hard-coded, every time there is a change in interface requirements, it is necessary to re-modify the code, compile and connect, etc. to realize the change in requirements, which cannot meet various flexibility and individualization requirements. The flexibility here is mainly the flexible customization of the interface. the

4) The installation and maintenance costs of the system are high. This method requires the installation of a user terminal program before it can be used, and if the user wants to perform network management on multiple machines, especially on a remote machine, multiple sets of user terminal software must be installed at the same time. In addition, when the user terminal software has a problem or needs to be upgraded, all user terminal software needs to be updated, which brings a lot of overhead to system maintenance. the

5) It cannot meet the cross-platform requirements of user terminals. Generally speaking, operating systems of user terminals are different, and corresponding user terminal programs are also different. However, it is also unrealistic to design a user terminal program for each operating system. Requiring customers to abandon the existing operating system to buy a new operating system will make customers pay a lot of money. the

Through this technology, the system can dynamically distribute the processing flow among the servers, realize sharing and efficiently utilize resources, and avoid single-point performance Bottlenecks increase the processing power of the entire system. the

(6) Easy to upgrade and maintain. The user terminal only needs a browser, and no configuration or upgrade is required. The server side adopts distributed component structure and XML (the Extensible Markup Language, Extensible Markup Language) files to define all business functions and interfaces in the network management system. With this structure, when the network management requirements change, only the corresponding business components and configuration files need to be changed, without changing other parts, compiling the entire system, restarting the system, or redistributing customer applications to realize existing Changes in services, addition of new services, and abandonment of old services can easily meet different network management change requirements. the

(7) Interface friendliness. The user terminal interface is web-based, which is more direct and easier to use than the web management interface of traditional applications. In addition, the present invention can configure different pages for different users, such as login, logout, success or failure, so as to meet the personalized needs of different users and improve user satisfaction. the

(8) Convenience. The network management system is based on the Web, which allows network managers to use any kind of Web browser to conveniently and quickly configure, control, access and other management operations on any node in the network, changing the past that can only be limited to the network Mode for network administration on the management station. the

(9) Reduce the cost of network management. Browser operations and web pages are very familiar to network management users, which will greatly reduce the cost of user training, and at the same time promote more users to use the network management system to manage the network, reducing network operation and maintenance costs. In addition, since the core computing and storage of network management are all on the Web server, business management server, business processing server, and data storage server, the Web browser only needs a general machine with an appropriate amount of space, so that customers can use it on a simple and cheap client computer. Manage the network. the

(10) Reduce development costs. In the present invention, the logic of interface representation is separated from the logic of network computing, so that the personnel in charge of interface development can complete the page development work without mastering the complex logic of network management, so that the work of front-end developers and background developers is completely separated. Thus ensuring high efficiency and low cost development. the

Specifically, if the monitoring module finds that the monitored process is in a normal running state, it will automatically enter the next polling period; if it detects that the monitored process has exited, it will be restarted. After restarting a certain number of times, the monitored process still exits. At this time, there may be a problem with the operating system, and the process to be monitored cannot be simply restarted. Therefore, the operating system needs to be restarted so that the environment parameters in the operating system, etc. Reinitialize before running the monitored process. The guard monitoring module is used to monitor the changes of the configuration files in the network management system, and dynamically refresh these changes to the running network management system, thereby realizing hot swapping of network management functions. The configuration file is in XML format, which describes the deployment structure and its association in the network management system. Through the dynamic customization and updating of configuration files, the flexible expansion and deletion of network management functions can be realized.

The Web service module mainly provides HTTP and CORBA services, and provides a Web operating environment for the interface representation framework module and the interface plug-in module, and it starts with the startup of the physical machine where it is located. The interface presentation framework module provides an interface presentation platform for accommodating, managing and controlling interface plug-in modules. The interface plug-in module completes the basic functional interface representation function in network management, and these plug-in modules can be configuration management interface modules, security management interface modules, fault management interface modules, performance management interface modules or billing management interface modules, or can be User-defined interface display module. The physical carrier of all interface plug-in modules is a web page file package including HTML, JSP, Java class, XML file, etc. These file packages provide an independent and unified main interface interface. The task distribution module here is responsible for distributing the CORBA request from the Web service module to the business management layer module, specifically selecting the most idle business management server as the target machine. the

The Web service layer module is also provided with a load balancing server. The load balancing server here is the control and distributor of the Web service layer module. All user Web requests go to this server first, and then the server distributes the requests to an actual Web server according to the busyness of each Web server. The public domain name and IP address belong to this server. What is explained here is that this load balancer can be omitted when there are not many network management users. In this case, the function of the load balancer is integrated into an actual web server. At this time, users directly Interact with the web server. the

Referring to Fig. 4, the network management system is also provided with a monitoring module for monitoring the process of each server, so as to ensure the long-term stable operation of the network management system. Fig. 6 is a detailed structural diagram of the monitoring module. the

Referring to Figure 6, the monitoring module includes: an access server monitoring module that is independently set, connected with the access server and monitors its process; a database server monitoring module that is independently set, connected with the database server and monitors its process; independently set, The business processing server monitoring module is connected with the business processing server and monitors its process; the business management server monitoring module is set independently, connected with the business management server and monitors its process; the Web server monitor is set independently, connected with the Web server and monitors its process Module; a load balancing server monitoring module that is set independently, connects to the load balancing server and monitors its process. the

The relationship between the monitoring module and the monitored server is the relationship between the monitor and the monitored, and the communication between the two is realized by using the inter-process communication mechanism provided by the operating system. the

Referring to Fig. 4, the network management system further includes a naming service module for storing all object names and their object references. The naming service module is based on the standard naming service provided by CORBA. It stores the object names and object references of all CORBA objects registered in the network management system in the form of directory structure. Through the naming service module, the corresponding object reference can be retrieved according to the object name, so as to realize the transparent access to the CORBA object. the

The configuration files include system configuration files, interface description files and authority configuration files. the

The information of described Web service layer module, business management layer module, business processing layer module, data storage layer module, access layer module is all configured in a centralized system configuration file. The configuration is carried out in a hierarchical manner. The first level is the configuration items of the above five modules. For these modules, its configuration information mainly includes the module name, module level and information about all physical servers contained in each module. The item configuration information determines how many physical servers the layer module will run on. The second level is the configuration information of the physical server, which includes the name of the physical server, the IP address and the information of the functional modules it includes. The configuration information of the physical server determines what kind of function the server will realize. The third level is the configuration information of the function module, which includes the name and type of the function module, interface information with other function modules, start parameters, stop parameters and the operation information included in the function module. The configuration information of the function module determines the function module. The specific operations performed by the function module and the relationship with other modules. The fourth level is the configuration information of the operation, which includes the operation name, identification, call parameters, whether the processing identification of the next layer of functional modules is required, etc. The configuration information of the operation determines the processing flow of the business request. the

In order to complete the start and stop of the network management system, the system configuration file also sets the start sequence of each module when the system is initialized and the stop sequence of each module when the system stops. the

Through the system configuration file, it can solve the problems that the existing network management system cannot realize dynamic configuration, and the function modules cannot be disassembled and combined arbitrarily, so as to realize the flexible configuration of the network management system and the arbitrary combination and disassembly of the function modules, thereby improving the efficiency of the network management system. Customized support capability. the

The configuration information of the interface plug-in module is set in the interface description file (in XML format) according to the function type. Each functional interface category is assigned a corresponding interface representation interval (such as an integer interval), any specific interface in which corresponds to a specific integer in the integer interval, and this integer can serve as an interface plug-in identifier (interface plug-in ID) , there can be multiple integers in the interface representation interval, and each integer corresponds to a functional interface. For example, the configuration management function interface is defined as [1000..1999], the performance management interface is positioned as [2000..2999], etc. Through this interface description file, define and describe all determined interfaces, and reserve processing interfaces for new interfaces that may be added in the future. In the interface description file here, the first level is the configuration information of the interface type, including the interface type and the corresponding integer range, and the second level is the specific interface information, including the specific interface ID, access parameters, corresponding background function modules and other information , the third level is specific operation information, including specific trigger events, call parameters, corresponding background function objects and other information. the

The configuration information of network management users and their operating rights are all set in the rights configuration file. The authority configuration file is a graded file. The first level of the configuration file is user information, including user name, user identification number, etc., the second level is the owned interface information, including interface ID, etc., and the third level is user information. It is the owned operation information, including operation name, ID, etc. the

There are also guard monitoring modules for system configuration files, interface description files and authority configuration files. The guard monitoring module is responsible for monitoring the changes of each configuration file (such as adding or deleting physical servers or functional modules in the system configuration file), and parsing and reading the changed configuration file into the memory object. When each module of the network management system is relatively idle, the guard monitoring module will dynamically update these configuration changes to the physical server of the relevant module. During this period, there is no need to restart any server, so as to realize the hot swap of network management functions. the

Referring to Fig. 9, the following describes the service request processing process in the network management system of the present invention in detail. the

Step 901, the user terminal sends a web page service request to the load balancing server. the

Step 902, the load balancing server judges whether the service request is legal, if so, execute step 904, otherwise, execute step 903. the

The service request includes user name, password and login number and network management operation information such as querying the running status of network elements. The network management operation information includes commands and parameters, and the described commands are the submodule name+function of the core function module Object name + method or property of the function object. When the function object name is unique in the network management system of the present invention, the submodule name of the core function module can be omitted, as the function object is FORM, and the attribute is Title, then the command can be: FORM.Title="You Are Good". When the user name, password and login number correspond to the user name, password and login number saved on the load balancing server, it means that the request is legal; otherwise, it means that the request is illegal. the

Step 903, the load balancing server returns an error message to the user terminal, and then executes step 930: end this process. the

Step 904, select the most idle available web server according to the load sharing principle and distribute the service request to the selected web server for execution. the

Step 905, the web server receives and analyzes the service request, determines whether the service request is legal, if legal, then judges whether it can complete the service request according to the system configuration file, if it can be completed, then executes step 906, otherwise, then executes step 907. If it is illegal, the service request can be discarded directly, and an error message can be returned to the user terminal. the

Step 906, for a static page (file in html or htm format), the web server directly transmits the requested file to the user terminal browser, and the browser interprets and executes it and displays the final result to the user. For dynamic pages (files in jsp format), the Web server finds the corresponding file according to the request information and executes the Java class corresponding to the file. Then the result (in HTML or XML format) is sent back to the user's terminal browser in the form of HTTP. the

Step 907, the task distribution module selects a business management server that is the most idle, and sends the request to the selected business management server. the

Step 908, the service management server receives and parses the request from the web server, and judges whether it can complete the service request according to the system configuration file, if so, executes step 909, otherwise, executes step 910. the

Step 909, the service management server processes the service request, for example, checks whether the parameter type, format and content of the request are correct. If it is illegal, directly return the error message to the Web server, if it is legal, perform corresponding operations according to the request, such as querying the running status of each module in the system, querying the permission configuration information in the system, etc., and pack the processing results into a standard data format and return it to the Web server, and then execute step 906. the

Step 910, select a most idle business processing server in the business processing module, and convert the business request into a standard CORBA request and send it to the selected business processor. the

Step 911, the service processor receives and parses the service request from the service management server, and judges whether the service can be completed by itself or interacting with the database service layer module according to the system configuration file. If so, perform step 912; otherwise, perform step 913. the

Step 912 , the business processing server packs the processed result or the result of interaction with the database service layer module and sends it to the business management server, and then executes step 909 . the

Step 913: Select the most idle access server in the access layer module, and send the service request to the selected access server. the

Step 914, the access server receives and parses the service request from the service processing server, converts the service request into a protocol format that the managed network element can recognize, and sends it to the corresponding managed network element. the

Step 915, the managed network element receives and parses the service request from the access server, and processes the service request (for example, executes the command requested from the access server, or queries the operation status of the network element itself, restarts, etc.). the

Step 916, the managed network element sends back the processing result to the access server of the access layer module. the

Step 917, the access server of the access layer module converts the information returned by the managed network element into a standard data format that the network management system can handle, and then returns it to the service processor of the service processing layer module, and then executes step 912, Until the result returned by the managed network element is sent to the user terminal. the

Step 930, end this process. the

According to the present invention, in addition to adopting the standard HTTP protocol between the user terminal and the Web service layer module, the default CORBA interface of both is adopted, and the default interface of both is adopted between the Web service layer module and the business management module. The default interface between the business management layer module and the business processing layer module is used, the default interface is used between the business processing layer module and the data storage layer module, and the default interface is used between the business processing layer module and the access layer module. The default interface of the two is used between the access layer module and the managed network element. The default interfaces between the above layers can be the same or different. In principle, as long as the two layers can recognize each other, the default interfaces between the two layers can also be changed at any time. In this way, only the information flow through normal channels can be accepted and processed, thus preventing the attacks of illegal resident programs such as hackers and improving the security of the system. the

Therefore, according to the present invention, from the aspect of the basic framework system, the present invention provides a general, open and extensible framework system. Secondly, in order to provide users with the largest range of choices, the present invention is designed on the basis of an open standard (CORBA) framework, and has platform independence, such as not only supporting Unix operating systems, but also supporting Windows and Linux operating systems. At the same time, the adapter in the access layer module can support standard-based network management protocols, such as SNMP and CMIP, as well as TCP/IP protocol family and some other dedicated network protocols. the

Specifically, the present invention has the following beneficial effects:

(1) Cross-platform. Because this network management system is based on the CORBA specification, the developed system is truly cross-platform. The user terminal directly adopts a standard browser, and there is no restriction on the operating platform of the user terminal. the

(2) High scalability. It can realize non-disruptive upgrade of the system in both hardware and software. If the business processing layer module, business management layer module or Web service layer module is overloaded, corresponding processing servers can be added, and the system can automatically realize load sharing, thereby enhancing the processing capacity of the entire network management system. If there is a new business requirement, as long as the new business processing object conforming to the CORBA specification is developed, it can be easily integrated into the existing network management system through the configuration file. the

(3) High security. The data storage layer can only be accessed by the business processing layer, and the access here must be authenticated, other layers cannot be accessed, and there is no logical association between the Web user terminal and the data storage layer, thus avoiding illegal access by users. Between the user terminal and the Web service layer module, between the Web service layer module and the business management layer module, between the business management layer module and the business processing layer module, between the business processing layer module and the data storage layer module, between the business processing layer module and the access layer module By adopting the default interface, through layer-by-layer information control, it can effectively prevent malicious attacks and information theft from the network, and effectively ensure the security of the network management system. the

In addition, the system authorizes each interface and its operation through the authority configuration file, which restricts the illegal use of system function modules, thus ensuring the security of the entire system. the

(4) High reliability. The present invention adopts a multi-server redundancy mechanism in the core function module. If one of the servers fails, the remaining servers with the same function can immediately replace the work, thereby ensuring the uninterrupted processing of the system and avoiding the problem of single point failure. . In addition, the monitoring module in the network management system can detect the status of the system service in real time and restore it immediately when the service is abnormal. the

(5) High performance. The network management system of the present invention adopts a multi-server distributed structure and a load balancing strategy. Through this technology, the system can dynamically distribute the processing flow among the servers, realize sharing and efficiently utilize resources, and avoid single-point performance Bottlenecks improve the processing power of the entire system. the

(6) Easy to upgrade and maintain. The user terminal only needs a browser, and no configuration or upgrade is required. The server side uses distributed component structure and XML files to define all business functions and interfaces in the network management system. With this structure, when the network management requirements change, only the corresponding business components and configuration files need to be changed, without changing other parts, compiling the entire system, restarting the system, or redistributing customer applications to realize existing Changes in services, addition of new services, and abandonment of old services can easily meet different network management change requirements. the

(7) Interface friendliness. The user terminal interface is web-based, which is more direct and easier to use than the web management interface of traditional applications. In addition, the present invention can configure different pages for different users, such as login, logout, success or failure, so as to meet the personalized needs of different users and improve user satisfaction. the

(8) Convenience. The network management system is based on the Web, which allows network managers to use any kind of Web browser to conveniently and quickly configure, control, access and other management operations on any node in the network, changing the past that can only be limited to the network Mode for network administration on the management station. the

(9) Reduce the cost of network management. Browser operations and web pages are very familiar to network management users, which will greatly reduce the cost of user training, and at the same time promote more users to use the network management system to manage the network and reduce network operation and maintenance costs. In addition, since the core computing and storage of network management are all on the Web server, business management server, business processing server, and data storage server, the Web browser only needs a general machine with an appropriate amount of space, so that customers can use it on a simple and cheap client computer. Manage the network. the

(10) Reduce development costs. In the present invention, the logic of interface representation is separated from the logic of network computing, so that the personnel in charge of interface development can complete the page development work without mastering the complex logic of network management, so that the work of front-end developers and background developers is completely separated. Thus ensuring high efficiency and low cost development. the
