Description
技术领域technical field
本发明涉及网络技术领域，尤其涉及一种网络重构的方法及系统。The present invention relates to the field of network technology, in particular to a method and system for network reconfiguration.
背景技术Background technique
随着云计算技术和网络虚拟化技术的发展，OpenStack提供了一套部署云的操作平台或工具集，为云计算基础设施服务提供解决方案。OpenStack具有开源、互操作性、可移植性、易用性的特点，而且还提供开发的应用程序编程接口(Application Programming Interface，简称：API)，以便进行二次开发，能够方便的与其他系统进行集成，赢得业界越来越多的关注。With the development of cloud computing technology and network virtualization technology, OpenStack provides a set of operating platforms or tool sets for cloud deployment, and provides solutions for cloud computing infrastructure services. OpenStack has the characteristics of open source, interoperability, portability, and ease of use, and also provides an application programming interface (Application Programming Interface, referred to as: API) for secondary development, which can be easily integrated with other systems. Integration has won more and more attention from the industry.
网络功能虚拟化(Network Function Virtualization，简称：NFV)平台的目标是通过基于行业标准的服务器、存储和网络设备，来取代私有专用的网元设备。NFV基础设施必须是跨地理位置分布式部署的，NFV架构下的虚拟基础设施管理(Virtualized Infrastructure Manager，简称：VIM)的职责是控制和管理网络功能虚拟化基础设施，如计算、网络和存储等资源，可以通过增强OpenStack的功能实现VIM的功能以支持多站点的NFV平台。The goal of the network function virtualization (Network Function Virtualization, NFV for short) platform is to replace private and dedicated network element devices with industry standard-based servers, storage and network devices. The NFV infrastructure must be distributed across geographic locations. The virtual infrastructure manager (Virtualized Infrastructure Manager, VIM) under the NFV architecture is responsible for controlling and managing network function virtualization infrastructure, such as computing, network, and storage. Resources, the function of VIM can be implemented by enhancing the function of OpenStack to support the multi-site NFV platform.
随着云计算的部署和实际的应用，跨地域、大规模以及分级化的部署需求强，应用广。在实际部署时每个站点(可认为地理位置分散的区域或数据中心)均会独立运行一套OpenStack云系统，并且该站点的可处于自治状态独立运行，同时可处于多站点的NFV平台的管理，这样就存在站点处于自治状态下创建的网络、子网和虚拟机，接入NFV平台后，需要在NFV平台上呈现总体的网络信息，这样站点的网络同步信息在NFV平台上重构就成为一个亟待解决的问题。With the deployment and actual application of cloud computing, the demand for cross-regional, large-scale and hierarchical deployment is strong and the application is wide. In actual deployment, each site (which can be considered as a geographically dispersed area or data center) will independently run a set of OpenStack cloud systems, and the site can operate independently in an autonomous state, and can be managed by a multi-site NFV platform , so that there are networks, subnets, and virtual machines created when the site is in an autonomous state. After accessing the NFV platform, the overall network information needs to be presented on the NFV platform, so that the network synchronization information of the site can be reconstructed on the NFV platform. A burning problem.

If the site subnet ID If it does not exist in the subnet identifier mapping identifier, create the subnet corresponding to the site and the virtual machines under the subnet, that is, when the site is not building a complete network in the NFV platform, the NFV platform will build a Network and virtual machines under the subnet, and create a subnet ID mapping table between the platform subnet ID and the site subnet ID, and create a virtual machine mapping table between the platform virtual machine ID and the site virtual machine, so that the site is on the NFV platform It is possible to reconstruct the network corresponding to the site.
进一步，若是NFV平台检测到该站点对应的站点子网标识存在于子网标识映射表中时，NFV平台对该子网下的虚拟机信息进行检测处理，具体的检测处理过程如下：Further, if the NFV platform detects that the site subnet ID corresponding to the site exists in the subnet ID mapping table, the NFV platform detects and processes the virtual machine information under the subnet, and the specific detection process is as follows:
NFV平台获取网络同步信息中的站点虚拟机标识，判定站点对应子网下的站点虚拟机标识是否存在于虚拟机标识映射表中，若站点虚拟机标识存在于虚拟机标识映射表中时，检测虚拟机与子网下的其他虚拟机是否存在冲突，若存在冲突，则向站点返回同步失败信息，若不存在冲突，则将虚拟机对应的虚拟机信息覆盖原有的虚拟机信息，也就是说，子网下虚拟机不存在冲突的情况下，NFV平台将通过获取到的虚拟机信息更新原有的虚拟机信息，从而通过网络同步信息重构该站点对应网络，进而保证站点对应网络能够及时更新。The NFV platform obtains the site virtual machine ID in the network synchronization information, and determines whether the site virtual machine ID under the subnet corresponding to the site exists in the virtual machine ID mapping table. If the site virtual machine ID exists in the virtual machine ID mapping table, it detects Whether there is conflict between the virtual machine and other virtual machines under the subnet. If there is a conflict, the synchronization failure information will be returned to the site. If there is no conflict, the virtual machine information corresponding to the virtual machine will overwrite the original virtual machine information, that is, In other words, if there is no conflict in the virtual machines under the subnet, the NFV platform will update the original virtual machine information through the obtained virtual machine information, thereby reconstructing the network corresponding to the site through network synchronization information, thereby ensuring that the network corresponding to the site can renewed on time.
若是站点虚拟机标识未存在虚拟机标识映射表中时，检测虚拟机与已有的虚拟机是否存在冲突，若存在冲突，则向站点返回同步失败信息，若不存在冲突，则创建子网下的虚拟机，并创建以及保存平台虚拟机标识与站点虚拟机标识的虚拟机标识映射表。也就是说，在虚拟机不存在当前子网下，NFV平台将在该子网下创建不存在冲突的虚拟机，这样通过网络同步信息重构该站点对应网络，进而保证站点对应网络能够及时更新。If the virtual machine ID of the site does not exist in the virtual machine ID mapping table, check whether there is a conflict between the virtual machine and the existing virtual machine. If there is a conflict, return the synchronization failure information to the site. If there is no conflict, create a subnet virtual machine, and create and save a virtual machine ID mapping table between the platform virtual machine ID and the site virtual machine ID. That is to say, if the virtual machine does not exist in the current subnet, the NFV platform will create a virtual machine in the subnet without conflicts, so that the corresponding network of the site can be reconstructed through network synchronization information, thereby ensuring that the corresponding network of the site can be updated in time .
下面通过图2对上述的内容进行简要说明，在图2中，站点向NFV平台发起连接，NFV平台向站点返回接受连接，这样NFV平台与站点之间就建立连接，站点启动网络同步，站点向NFV平台发送网络同步信息，NFV平台接收到该网络同步信息之后，NFV平台处理该网络同步信息，并进行网络重构，在重构完成之后，NFV平台将向站点反馈网络同步完成响应，这样就完成了网络信息同步过程。Below is a brief description of the above content through Figure 2. In Figure 2, the site initiates a connection to the NFV platform, and the NFV platform returns to the site to accept the connection. In this way, a connection is established between the NFV platform and the site, and the site starts network synchronization. The NFV platform sends network synchronization information. After the NFV platform receives the network synchronization information, the NFV platform processes the network synchronization information and performs network reconstruction. After the reconstruction is completed, the NFV platform will feed back the network synchronization completion response to the site, so that The network information synchronization process is completed.
进一步，在本发明实施例中，NFV平台在获取网络同步信息时，该将检测是否接收到站点上报的同步结束标识，若是接收到同步结束标识时，则删除平台上已使用的网络同步信息，若未接收到同步结束标识时，则继续检测站点上报的网络同步信息，也就是说，站点在完成网络同步信息的上报之后，站点会将同步结束标识发送给NFV平台，这样NFV平台能够及时停止对该站点的网络同步，从而避免出现网络资源浪费，并且也可以减少NFV平台的运行压力。Further, in the embodiment of the present invention, when the NFV platform acquires network synchronization information, it will detect whether the synchronization end identifier reported by the site is received, and if it receives the synchronization end identifier, then delete the used network synchronization information on the platform, If the synchronization end identification is not received, continue to detect the network synchronization information reported by the site, that is, after the site completes the reporting of the network synchronization information, the site will send the synchronization end identification to the NFV platform, so that the NFV platform can stop in time The network synchronization of the site avoids waste of network resources and reduces the operating pressure of the NFV platform.
综上来讲，在本发明实施例中NFV平台获取站点发送的网络同步信息，判定网络同步信息中的站点网络标识是否存在于预存的网络标识映射表中，若站点网络标识未存在于网络标识映射表中时，基于网络同步信息创建站点对应网络、子网以及虚拟机，以构建站点对应网络；若站点网络标识存在于网络标识映射表中，则基于获取到的网络同步信息，更新站点对应的站点信息。通过上述的方法可以及时的将站点的网络拓扑结构进行重构，这样方便用户多层次的查看网络部署情况。To sum up, in the embodiment of the present invention, the NFV platform obtains the network synchronization information sent by the site, and determines whether the site network identifier in the network synchronization information exists in the pre-stored network identifier mapping table, if the site network identifier does not exist in the network identifier mapping table When in the table, create the network, subnet, and virtual machine corresponding to the site based on the network synchronization information to build the network corresponding to the site; if the site network identifier exists in the network identifier mapping table, update the corresponding Site Information. Through the above method, the network topology structure of the site can be reconstructed in time, which is convenient for the user to check the network deployment status at multiple levels.
另外需要说明的是，上述的过程说明的是一个站点对应的网络同步，其他站点的同步过程上述的过程一致，在本发明实施例就不再一一说明。In addition, it should be noted that the above process describes the network synchronization corresponding to one site, and the synchronization process of other sites is the same as the above process, and will not be described one by one in the embodiment of the present invention.
