Method and system for acquiring routing table in data center

Abstract

The invention discloses a method and a system for acquiring a routing table in a data center. The method comprises: a step of acquiring an OSPF network routing table, i.e., acquiring a Router LSA and a Network LSA, calculating an intra-domain routing of an OSPF network according to the Router LSA and the Network LSA, acquiring a Summary LSA, calculating a routing between region routings, acquiring an AS External LSA, and calculating an autonomous domain external routing; and a step of acquiring an ISIS network routing table, i.e., acquiring a data table Link_state_main and a data table Link_state_attach, inquiring equipment names of all routing equipment in the Link_state_main, using the equipment names as ids, inserting the ids into a graphic database Neo4j so as to acquire all the routing equipment, establishing a linking relationship for all the routing equipment, acquiring LSPs generated by all pseudo nodes, traversing the LSPs generated by the pseudo nodes of all the routing equipment, inserting the linking relationship among all the routing equipment into the graphic database Neo4j, adding a distance value metric for the linking relationship, and according to a set generated by all the routing equipment, acquiring the routing table.

Description

technical field [0001] The invention relates to the technical field of computer network interconnection communication, in particular to a method and system for obtaining a routing table in a data center. Background technique [0002] With the development of cloud computing and big data, the construction of IDC data centers has ushered in a construction climax. As the cost of data centers continues to soar, the focus of data center management has begun to shift to network operation and maintenance and network optimization. In the process, the routing table has become a very important basic data. With the routing table data, the path from any node to the destination node can be grasped, thus laying the foundation for traffic engineering, network optimization and network modeling. [0003] The existing routing table acquisition methods are roughly divided into three types: log in to the router CLI to collect, provide by the manufacturer, and collect from the network. Logging i...

Problems solved by technology

Logging in to the router to view often requires manual assistance. Due to the large number of routers in the data center and the different routing table formats of routers from different manufacturers, this method is less feasible to obtain the routing table; manufacturers often need to configure dedicated routers to provide external output routing tables Interface, the routing table obtained by this method is more accurate, but the price is relatively expensive, and the routing table data of non-dedicated routers cannot be collected; the network collection mainly uses the flood link state information in the network and uses the SPF algorithm to calculate the route. High cost performance, providing more accurate restoration routing table, and high real-time performance
