Description

一种实现接入设备扩缩容的方法和装置Method and device for realizing expansion and contraction of access equipment

技术领域Technical field

本文涉及但不限于网络应用技术领域，尤指一种实现接入设备扩缩容的方法和装置。This document relates to, but is not limited to, the field of network application technologies, and in particular, to a method and apparatus for implementing expansion and contraction of an access device.

背景技术Background technique

随着网络技术的发展，IPRAN/PTN(IP Radio Access Network/Packet Transport Network，无线接入网IP化/分组传输网)等分组传送技术在运营商网络得到了大量的应用和推广。IPRAN/PTN的网络包括汇聚设备、接入设备、和核心设备。下面结合附图进行说明，如图1所示，示出了一种IPRAN/PTN最典型的网络，包括两个B设备(汇聚设备)，若干个A设备(接入设备)组成接入层网络，以及B设备与C设备(核心设备)相连的核心汇聚层网络。接入层网络涉及隧道(Tunnel)/伪线(PW)/业务(Service)三个层次的管理，并且还包括与三个层次相关的操作维护管理OAM、服务质量QoS的配置。With the development of network technology, packet transmission technologies such as IPRAN/PTN (IP Radio Access Network/Packet Transport Network) have been widely applied and promoted in carrier networks. The network of the IPRAN/PTN includes an aggregation device, an access device, and a core device. The following is a description of the accompanying drawings. As shown in FIG. 1 , a typical network of IPRAN/PTN is shown, including two B devices (aggregation devices), and several A devices (access devices) form an access layer network. And a core aggregation layer network where the B device is connected to the C device (core device). The access layer network involves three levels of management of tunnel/pseudowire (PW)/service (Service), and also includes three levels of operation and maintenance management OAM and quality of service QoS configuration.

随着运营商业务规模不断扩展以及新业务不断接入，经常需要在已经承载了业务的接入层网络增加或者减少一个或若干个A设备，或者对多个接入环进行拆分与重组，即实现接入设备的扩缩容。针对这种维护场景，维护人员需要规划配置大量数据，如图2A和图2B所示，其中，图2A中表示在A设备和B设备之间需要增加新节点，即新的接入设备，图2B中简单示意了维护人员需要规划和配置的管理操作，例如接口地址、IGP协议、隧道、OAM等多种基础配置。上述规划和配置的管理操作增加了网络的维护难度和成本，对维护人员的专业能力也提出了很高的要求，如果维护人员对规划和配置的管理操作不是非常的理解和熟悉，将造成维护工作的时间延长。As the service scale of the carrier continues to expand and new services are continuously accessed, it is often necessary to add or reduce one or several A devices or split and reassemble multiple access rings on the access layer network that has already carried the service. That is to achieve the expansion and contraction of the access device. For this maintenance scenario, the maintenance personnel need to plan to configure a large amount of data, as shown in Figure 2A and Figure 2B. Figure 2A shows that a new node, that is, a new access device, needs to be added between the A device and the B device. 2B simply indicates the management operations that maintenance personnel need to plan and configure, such as interface address, IGP protocol, tunnel, OAM, and other basic configurations. The above-mentioned planning and configuration management operations increase the maintenance difficulty and cost of the network, and put forward high requirements for the maintenance personnel's professional capabilities. If the maintenance personnel are not very understanding and familiar with the planning and configuration management operations, it will cause maintenance. The working time is extended.

在介绍本发明实施例提出的实现接入设备扩缩容的方法和装置之前，首先对IPRAN/PTN SDN网络进行简单介绍。本发明实施例中的网络指IPRAN/PTN SDN网络，或IPRAN/PTN网络。Before introducing the method and device for implementing the expansion and contraction of the access device proposed by the embodiment of the present invention, the IPRAN/PTN SDN network is briefly introduced. The network in the embodiment of the present invention refers to an IPRAN/PTN SDN network, or an IPRAN/PTN network.

IPRAN/PTN SDN网络:与传统的IPRAN/PTN网络相比，基于SDN网络的交换机或者路由器只存在转发面(数据面)的逻辑，主要是根据控制器的逻辑完成转发，通过Openflow协议(或者其他协议)实现与本发明实施例中的SDN控制器互通，如图3所示，为IPRAN/PTN SDN网络的示意图。IPRAN/PTN SDN network: Compared with the traditional IPRAN/PTN network, the SDN network-based switch or router only has the logic of the forwarding plane (data plane), mainly based on the logic of the controller to complete the forwarding, through the Openflow protocol (or other The protocol implements interworking with the SDN controller in the embodiment of the present invention, as shown in FIG. 3, which is a schematic diagram of an IPRAN/PTN SDN network.

SDN控制器：SDN控制器(Controller)通过Openflow协议(或者其他协议)实现与接入层网络SDN交换机互通，通过建立若干个虚拟路由器VR(Virtual ROUTER，虚拟路由器)管理接入层网络设备业务信息，每个VR包含至少一个或两个B设备和若干个A设备，如图4所示，为VR的示意图。SDN控制器负责自动计算设备拓扑以及业务数据转发控制信息，并且实时更新维护拓扑、业务数据信息，将变更通过websocket方式(或者其他方式)推送到本发明实施例所述的实现接入设备扩缩容的装置中。SDN controller: The SDN controller (Controller) communicates with the access layer network SDN switch through the Openflow protocol (or other protocol), and manages the access layer network device service information by establishing a number of virtual routers VR (Virtual ROUTER). Each VR includes at least one or two B devices and a plurality of A devices, as shown in FIG. 4, which is a schematic diagram of the VR. The SDN controller is responsible for automatically calculating the device topology and the service data forwarding control information, and updating the maintenance topology and the service data information in real time, and pushing the change to the access device according to the embodiment of the present invention by using the websocket method (or other means). In the device.

其他管理***：具有IPRAN/PTN接入层网络拓扑信息，能够向包含SDN控制器在内的其他***提供拓扑信息。Other management systems: With IPRAN/PTN access layer network topology information, it can provide topology information to other systems including SDN controllers.

本发明实施例所述的实现接入设备扩缩容的装置可以通过应用层协议调用控制器接口创建虚拟路由器，或者执行扩容指令的时候，所需的设备信息可以由其他管理***提供，这里其他管理***指具有网络的拓扑数据的***，因此该管理***是可选的。The apparatus for implementing the expansion and contraction of the access device according to the embodiment of the present invention may create a virtual router by using an application layer protocol to invoke the controller interface, or when performing the expansion instruction, the required device information may be provided by other management systems, where other A management system is a system that has topology data for the network, so the management system is optional.

参见图5A，本发明实施例提出了一种实现接入设备扩缩容的方法，所述方法应用于实现接入设备扩缩容装置中,所述装置包括:服务器、PC机或虚拟机VM，结合图5A所示，所述方法包括：Referring to FIG. 5A, an embodiment of the present invention provides a method for implementing expansion and contraction of an access device, where The method is applied to implement an access device expansion and contraction device, and the device includes: a server, a PC, or a virtual machine VM. As shown in FIG. 5A, the method includes:

步骤100，检测网络的物理拓扑是否发生扩缩容变化。In step 100, it is detected whether the physical topology of the network has undergone expansion and contraction changes.

步骤100中，所述检测网络的物理拓扑是否发生扩缩容变化包括如下方式中的至少一种：In step 100, the detecting whether the physical topology of the network has undergone expansion and contraction changes includes at least one of the following manners:

通过定时轮询拓扑变化，获知网络的物理拓扑是否发生扩缩容变化；By periodically polling the topology changes, it is known whether the physical topology of the network has undergone expansion and contraction changes;

根据设备Trap消息生成设备相关告警，通过分析所述设备相关告警完成网络的物理拓扑的更新，通过所述网络的物理拓扑的更新获知网络的物理拓扑是否发生扩缩容变化；Generating a device-related alarm according to the device Trap message, and completing the update of the physical topology of the network by analyzing the device-related alarms, and determining whether the physical topology of the network has undergone expansion and contraction changes by updating the physical topology of the network;

其中，定时轮询拓扑变化可以通过两种方法实现。一种是：SDN控制器通过Openflow packout将一个LLDP报文发送到设备，设备再将这个报文发送到相邻设备，相邻设备再将这个报文通过packin传送到SDN控制器，如此循环，完成整个拓扑LLDP邻居以及链路的检测，并通过上述检测过程获取网络的拓扑数据。另一种是：SDN控制器通过LLDP协议轮询设备LLDP邻居，发现一个邻居，再继续查找此邻居的邻居，直至每个相邻设备没有邻居发现，并通过上述轮询过程获取网络的拓扑数据。本发明实施例中的定时轮询拓扑变化可以通过SDN控制器实现。The timing polling topology change can be implemented by two methods. One is: the SDN controller sends an LLDP packet to the device through the Openflow packout, and the device sends the packet to the neighboring device, and the neighboring device transmits the packet to the SDN controller through the packet, and so on. The LLDP neighbors and links of the entire topology are detected, and the topology data of the network is obtained through the foregoing detection process.
