Embodiment Construction

[0072] In order to make the object, technical solution and advantages of the present invention clearer, a multi-AS router-level topology processing system and method of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0073] The multi-autonomous system router-level topology processing system and method of the present invention, by making the routing information collection probe establish a session with the BGP border router in the network, collect BGP routing update messages in real time in a passive manner, and then collect them according to the single autonomous system The received OSPF routing update message is analyzed and processed, and multiple topologies generated according to the single autonomous system algorithm are connected into a comple...

Abstract

The invention discloses a multi-autonomous system router level topological treatment system and a method. The system comprises at least one BGP border router and a plurality of single-autonomous systems, and also comprises a routing information gathering probe used for establishing an equal relationship conversation with the BGP border router in the network to gather a BGP route updating message in the network and sending the gathered routing information updating message to an analyzing and processing unit, the analyzing and processing unit used for analyzing and processing the BGP route updating message gathered by the information gathering probe and the OSPF route updating message gathered by the single-autonomous system and also used for updating the information database and ensuring the topologies generated by the single-autonomous system to be connected as an integrated router level topology. The multi-autonomous system router level topological treatment system and the method is based on the construction of the routing message and the update of the router level topology to ensure that the connection relationship of the topology and the router in the network can keep consistent, and the influence to the network can be reduced.

Description

technical field [0001] The invention relates to the technical field of network monitoring, in particular to a multi-autonomous system router-level topology processing system and method. Background technique [0002] Today's Internet (Internet) and larger network service providers (Internet Service Provider, ISP) are divided into a large number of autonomous systems (Autonomous System, AS). The autonomous system sets the management control area and the routing policy that acts on the autonomous system. Therefore, the Internet-level routing structure is often divided into two types: inter-domain and intra-domain. [0003] For inter-domain routing, the Border Gateway Protocol (Border Gateway Protocol, BGP) is a commonly used standard protocol. It runs on the border routers of each autonomous system and exchanges routing reachability information at the autonomous system level to complete inter-domain routing. routing. [0004] For intra-domain routing, there are a variety of ...
