IP DSLAM network supply method

The present invention relates to an IP DSLAM (IP Digital Subscriber Line Access Multiplexer) network provisioning system architecture, in particular to a combination of Business Process Management (BPM) and principle management. (Policy-Based Management, PBM), to assist managers in designing the flow of new services on the IP DSLAM network in the shortest possible time.

The previous network supply system architecture often required the experience of network designers for network design. However, with the trend of IP network, the traditional access device was gradually replaced by IP-DSLAM. The services provided by DSLAM network are more and more diverse, and the network is more and more flexible. It is no longer cost-effective to design the network by the experience of network designers alone. Therefore, commercial BPM (Business Process Management Business) is used. Process Management) products to control the increasingly complex network supply process are the hottest topics of the Next Generation Operations Support Systems (NGOSS). However, the current commercial BPM products are still in the Warring States era, and different manufacturers' BPM uses different Process Calculus technologies to complete the functions of Process Abstraction. These technologies are flawed and there are still many new ones. Process Calculus has sprung up like a mushroom, and there isn't a single Process Calculus that can solve all the complex network supply problems. Moreover, today's commercial BPM (Business Process Management) products are mainly for booking (Pre- Designed with flow control, it is not easy to respond to the increasingly complex telecommunication network changes; in contrast, the "IP DSLAM network" supply problem, not only have to face Constantly introducing new and highly customized products, the programmers are struggling, and the traffic on the IP network is changing rapidly. The network must be dynamically adjusted as the network traffic changes. (Network Rearrange) To save resources, today's commercial BPM products can't change the ongoing flow control at any time for dynamic adjustment. From this point of view, the network supply problem of the "IP DSLAM network" is no longer a problem for the general commercial BPM software.

It can be seen that there are still many shortcomings in the above-mentioned methods of use, which is not a good design, but needs to be improved, and if some commercial BPM products are used, it is not only too expensive, but also difficult to learn.

In view of the shortcomings arising from the above-mentioned conventional methods, the inventor of the present invention has improved and innovated, and after years of painstaking research, he finally succeeded in research and development of the "IP DSLAM Network" supply system architecture, with self-developed " The IP DSLAM network "BPM", together with the "IP DSLAM Network" PBM developed by itself, can not only reduce the cost of the "IP DSLAM network" supply system, but also shorten the system development time.

The object of the present invention is to provide a network evolution, and to flexibly adjust the ongoing construction flow control, achieve the purpose of optimizing resource utilization, meet the requirements of new service planning, and improve the supply rate, thereby improving the service supply. quality.

The second object of the present invention is to provide the manager with a clear grasp of the construction progress and quality, and to modify the rules for the flow control at any time in accordance with the special customization requirements. Since the present invention adopts a BPM and PBM management method for the "Domain-Specific" of the "IP-DSLAM network", the flow control design is independent of the program, and the manager does not have the information technology background. Simple flow control can be designed, which can greatly reduce the cost of system development and thus enhance the competitive advantage.

The IP DSLAM network supply system architecture that achieves the above-mentioned objects is designed in a BPM and PBM management manner. The BPM includes a "Channel Communication Engine" and a "Processing Processor" ( Four modules required for the supply phase of Pi-calculus Processor), Petri-net Workflow Processor and Flow Monitor, according to PBM The Petri-nets design of the construction process is carried out. The PBM includes the "Installation Rule Base Management Module", the "Personnel Transfer Rule Base Management Module", the "PBM Engine Module" and the "PBM Engine Module". The four main modules required for Petri-nets production module, etc., can manage the rules used in the "IP DSLAM Network" supply system and the Petri net for the construction process (Petri- Nets) design, the invention can greatly reduce labor costs, and provide a more manageable system architecture for broadband services.

Please refer to FIG. 1 , which is a system architecture diagram of an IP DSLAM network installation system architecture according to the present invention. The system architecture mainly includes:

One other operating system and software (OSS)1;

One channel (Chamel) 2;

A Business Process Management (BPM) 3, the business process management 3 receives the transaction request of the other operating system and the software 1 through the channel 2, and then sends the transaction request to the principle management 4 for the construction process. Designed by Petri-nets, the business process management 3 is based on the Petri-nets of the construction process; and the principle management 4 provides the manager with an abstraction flow control design. The process of simplifying system complexity is called Abstraction, so the Abstraction process is becoming more and more important as the system grows larger; therefore, the first step in the design of the IP DSLAM network supply system is to establish the supply rules. First, the manager must first remove the least frequently changed part of the flow control, and use the "Management Rule Base Management Module" of Principle Management 4 to design the extracted parts into relevant supply rules. After the management has completed the installation rules according to the degree of volatile, the staff dispatches the rule base management module to design the staff dispatch rules; when the relevant rules are designed After that, the Pi-calculus Processor of the business process management 3 executes a preset process in the provisioning rule library, and the principle is started when the preset process is executed to the provisioning action of the network. Management 4's rules engine module to perform network provisioning, the rules engine module will design the network according to the rules of the supply rules database, and then use Petri-nets to generate modules. The construction process Petri-nets, after which the rules engine module passes the Petri-nets of the construction process to the Petri-nets Workflow Processor of the business process management 3. Send a job;

Therefore, the main task of the business process management 3 is the workflow control of the entire resource (Workflow Control), and the use of a hybrid operation (Pi-calculus) and Petri-net (Petri-net) hybrid architecture to achieve a more simplified Process Abstraction purpose, including Channel Communication Engine, Pi-calculus Processor, Petri-net Workflow Processor and Flow Monitor The four modules required for the supply phase; wherein the channel communication engine module encapsulates the communication operations between the IP DSLAM network and other systems to the objects of channel 2. In the past, in the design of flow control, you need to consider the deadlock, the process of the process of the physical process (Distribution of Processes among Physical Processors) and bounce back a variety of failure types (Resilience to Various Kinds of Failures ) Concurrency Control issues, as well as architectural issues that face the need for Concurrency (such as Fork/) Wait, Cobegin/Coend and Data Parallelism), and data synchronization issues (Shared memory, Rendezvous, Message-passing, and Dataflow); the use of Pi-calculus, which hides these complexity in the Channel object. In this way, a good Process Abstraction can be obtained, so the administrator does not need to consider the above-mentioned synchronous operation when designing the flow control. The Pi-calculus is a channel-based operation. Therefore, the design of channel 2 is very important, and the main purpose of this module is to encapsulate the complexity of communication between all systems, which unifies different transmission modes into a simplified interface; There are two parts (input InPort and OutOut), which have a special synchronous communication, that is, you need to wait for the message to be sent back after the transmission. The communication component is named InOutPort by itself, and the input (InPort) provides The Input Port transmission mode can be divided into FTP, HTTP, FILE, SOCKET, Web service, JMS, and the Output Port transmission mode provided by the output port (OutPort) can be For FTP, HTTP, FILE, SOCKET, Web service, voice reminder, newsletter, e-mail, JMS; using this unified channel 2 interface, the system communication interface designer can quickly assemble a new transmission mode, or interface The data format is designed to meet the required communication format, and the address to be transmitted and received is injected into the communication profile by using the setting. The channel communication engine (Channel Communication Engine) can start receiving the communication Deamon according to the set setting, and the transmission part can be based on The set communication profile uses the acquisition of the transfer object to achieve the purpose of simplifying the communication step; for example, when we replace the underlying communication (Communication) with a new transmission method (EAI, Enterprise Application Integration Enterprise) Application Integration), at this point we can use the new communication method with a small part of the design of the new communication protocol, and the upper layer flow control design is completely unchanged; Step 1: Input (InPort) module design The function of this module is to receive the message from EAI JMS; Step 2: The OutPort module design, so that the function of this module is to transmit EAI JMS message.

The business process management 3 Pi-calculus Processor module uses Pi-calculus to simplify the control of the Message Routing process between the IP DSLAM network and each OSS system. The business process management 3 will be converted into a Pi-calculus Program according to the preset flow control defined by the principle management 4 (the device reset flow control diagram shown in FIG. 2), and then the operation processor (Pi) -calculus Processor) The IP DSLAM network exchanges information with other various interface systems to simplify the control of the message routing process between the IP DSLAM network and each maintenance support system. The execution sequence is as follows: Step 1: External system Put the input data into the EAI Message Box; Step 2: The Pi-calculus Processor uses the input (InPort) to obtain the integrated application information storage (EAI Message Box) in the enterprise application system. Input data; Step 3: Input (InPort) to transfer data to the Orchestration Message Box using the BPM messaging component; Step 4: Input (InPort) needs to be To coordinate the flow of information transferred the message store (Orchestration Message Box) internal message format; Step 5: Internal message will process the message coordination reservoir (Orchestration Message Box) global variable; step 6: The input of the Orchestration Message Box (InPort) of the coordination process receives the message from the Orchestration Message Box of the coordination process, and the call processing process controller (Orchestration Handler) Step 7: After receiving the message, the Orchestration Handler will judge the name and type of the component to be processed according to the source of the message; Step 8: If the previous message is not found in the Pi-calculus Processor, it will go Principle Management 4 looks for the "pre-defined process" and newly establishes this process in the Pi-calculus Processor; Step 9: If this message is already available, it will be utilized according to the Pi-calculus Processor. Correlation Id in the message is used as the primary key, and the source name is used to judge the name and type of the component to be processed; Step 10: According to the name of the component to be executed, use Spring (spring software) call component mode to execute the Process Operation.

In addition, the Petri-nets Workflow Processor module uses Petri-nets to design dynamic dispatch flow control for IP DSLAM networks. Petri Net (Petri) -nets) is very suitable for defining and analyzing complex dispatching processes. It is also easy for field operators or relevant supervisors to understand the construction progress according to Petri-net, and also avoid Ambiguities, Uncertainties, and conflicts. (Contradictions) and other issues; and the business process management 3 according to the principle of management of the output of Petri-nets (Petri-nets) to design the IP DSLAM network dynamic dispatch flow control, that is, through the Petri network Workflow Control Processor (Petri-nets Workflow Processor) module for dispatching work, and Petri Net Each transition in (Petri-nets) can have a Time Trigger, so the schedule of the Petri Nets Workflow Processor module (Scheduler) According to the pre-implementation date in the time trigger (Time Trigger), if the transition does not have a corresponding time trigger (Time Trigger), then immediately dispatch the fire (Fire); the Petri net workflow control The Petri-nets Workflow Processor module provides Undo, Redo, and Abort functions for each flow control. Therefore, each transition must also have a corresponding Undo action. When the user wants to log out the entire flow control, Pate When the Petri-nets Workflow Processor module acts as the Undo for the flow control, the system performs the corresponding Undo action for all the transitions that have been made; the process monitor (Flow Monitor) module, its main purpose is to monitor the entire workflow process (Workflow) process, not only can be clearly aware of the state of the flow control (see the flow control progress chart shown in Figure 4), more Manager Validity assessment tool.

Policy-based Management (PBM) 4, the main function of this principle management 4 is to manage the rules used by the IP DSLAM network provisioning system. Since IP DSLAM networks often provide highly customized products, In pursuit of the most efficient use of the network, the supply rules often change, so the principle management 4 can be used to manage complex business rules in a database of supply rules, allowing experts with domain knowledge to use it. The rule management tool (Rule Tool) provided by the system can store the workflow model, the assignment rule of the digital subscriber line access multiplexer (DSLAM Port), and the calculation rule of the route into the installation rule data. In the library; after the principle management 4 receives the Resource Order transmitted by the business process management 3, the principle management 4 derives the relevant rules for processing the joint order from the supply rule base according to the content thereof, and the business process Management 3 then makes network subscriptions based on these rules. After the network architecture is determined, the business process management 3 calculates the Petri nets (Petri-nets) of the construction flow control according to the network architecture and the related workflow model (Workflow Pattern), and then sends back to the principle management 4 to dispatch;

The principle management 4 includes four main modules required for the installation rule base management module, the personnel dispatch rule base management module, the rule engine module, and the Petri nets generation module; The supply rule database management module mainly manages the business rules that change rapidly, and the supply rules can be written in a natural grammar. The rules that can be processed are classified as follows:

The staff of Principle Management 4 dispatches the rule base management module, which provides personnel to dispatch rule management tools. Human resources is the company's most valuable resource. How to make human resources the most efficient deployment is IP DSLAM network supply The system is the most important key to save the company's operating costs. The IP DSLAM network supply system provides a very flexible staff dispatch rule management module to help managers achieve the goal of optimizing human resources. The dispatch rule management tool is provided, and the manager can change the relevant personnel at any time according to the dispatching rules (the person dispatching the rule management tool diagram shown in FIG. 3), and the rules that the manager must establish are classified as follows:

1. Personnel affiliation rules: Each person may have multiple roles at the same time (Role), belonging to multiple units or projects (Project, Case or Department), so there are many different bosses, directly under the boss (Hierarchical Boss) With the task-oriented boss (Functional Boss), even more can be interchanged in these roles, and the human DS organization of the IP DSLAM network supply system adopts the Matrix Organization structure, and the Matrix Organization will be the personnel subordinate rules. Divided into two types:

2. Personnel authority rules: This is the scope of responsibility of the relevant personnel. The management personnel can clear the scope of the responsibility area code (with the prefix of the phone number, the name of the station, the operation department, etc.). The definition of the relevant personnel's scope of responsibility:

3. Working Hours Management Rules: These rules are mainly used to provide the basis for job performance. Managers need to enter rules such as holidays, vacations, agents, different work priorities and weights into the system. The system can follow these rules. Assign a reasonable amount of work to relevant personnel, and provide objective and fair job performance analysis for managers' reference.

The Rule Engine module of the principle management 4 is the core module of the principle management 4. When the business process management 3 receives the Order from the front-end receiving system, the order is sent to the principle management 4 The rules of the rule engine module and the rule engine module are as follows:

Step 1: According to the requirements of the single order, go to the “Installation Rule Database” to find the corresponding “Provisioning Policy”;

Step 2: Find all available IP-DSLM devices in order from the “Assignment Order Rules” in the “Installation Rule Database”.

Step 3: Remove the inappropriate IP-DSLAM from the "Device Restriction Rule" in the "Installation Rule Database";

Step 4: Calculate the optimized network architecture from the "Connection Restriction Rules" and "Total Control Rules" in the "Installation Rules Database";

Step 5: Find the most suitable “construction resource” (including construction personnel, construction unit, EMS or NMS system) according to the designed network to “personnel dispatch rule base”;

Step 6: Then send the network architecture and related "construction Resource" to the "Petri-nets generation module" to calculate the Petri net (Petri-nets) of the construction process;

Step 7: Send the calculated Petri-nets to Principle Management 4 for dispatch.

In addition, the principle management 4 Petri nets (Petri-nets) generation module, its main purpose is to convert the network architecture into a construction process Petri-nets, as shown in Figure 5. After generating a module operation by Petri-nets, a Petri nets diagram of the relay network construction flow control as shown in FIG. 6 is generated; (Petri-nets) generation modules can be provided with a time trigger for each transition in Petri-nets.

The IP DSLAM network supply system architecture provided by the present invention has the following advantages when compared with other conventional technologies:

1. The present invention can enclose complex business rules in the Rule Base, plus not writing the process in the program, in the face of the meager profit era, the product life cycle is shorter and shorter. Quickly extract relevant rules from the Rule Base to assemble a new network service product to meet the ever-changing customer needs and significantly reduce the cost and labor cost of software development.

2. The present invention combines two popular techniques: Pi-calculus to design Pre-define flow control, and Petri-nets to design the Dynamic process. It can provide functions that are not available in general commercial BPM. The related functions are described as follows:

(1) When the IP DSLAM network construction flow control is in progress, the flow control can be interrupted by the user at any time, and the user can perform the flow control as Abort, Redo, or Undo at any time. It also has the ability to dynamically change the flow control in Run-time, and can perform the flow control in progress at any time, and perform the increase or decrease or the activity related to the activity.

(2) IP DSLAM network construction flow control may be modified at any time. Because the change of flow control is driven by network architecture or traffic changes (Trigger), there are many different sources that cause network architecture changes (such as temporary emergency changes to network resources, network changes) Connection system, accounting system, acceptance system, etc., and these different source changes can be arbitrarily fired at any time and without being synchronized with each other.

(3) IP DSLAM network construction flow control must be determined after the network architecture design is completed. The human resources involved in the construction cannot be defined in advance. This is a problem that commercial BPM lacking Input Mobility is not good at solving.

(4) The relationship between the Orders processed by the IP DSLAM network supply system is not independent. For example, the situation of the case after the case will cause confusion between Flow and Order.

(5) In the face of the acceptance system, there is a situation in which there is a burst of Burst Demands. At this time, the quantitative change will definitely cause a qualitative change, and there is a systemic crisis.

3. The invention allows the administrator to directly design a simple network for flow control, and can directly manage the network supply rules, and can change the ongoing construction flow control at any time according to changes in network traffic.

The detailed description of the preferred embodiments of the present invention is intended to be limited to the scope of the invention, and is not intended to limit the scope of the invention. The patent scope of this case.

To sum up, this case is not only innovative in terms of technical thinking, but also able to enhance the above-mentioned multiple functions compared with conventional articles. It should be submitted in accordance with the law in accordance with the statutory invention patents that fully meet the novelty and progressiveness, and you are requested to approve this article.
