Embodiment Construction

[0041] The purpose of the present invention is to perform data association according to network topology information and collected flow information in OSPF and ISIS network environments, and accurately and real-time reflect the result of network topology and flow data fusion.

[0042] The modules involved in the present invention include a message collection module, a routing topology analysis module, a traffic collection module and a routing traffic analysis module.

[0043] Wherein the concept in the present invention is: neighbor node: all neighbors of each topological node; stub area: the subnet area hanging under the border router; border area: all routers connected with other domains; internal area set: store and analyze neighbor nodes The result of the prefix area set: store the result of analyzing the stub area; boundary area set: store the result of analyzing the boundary area.

[0044] The following are the concrete steps of the present invention, as follows:

Abstract

The invention provides an OSPF and ISIS routing traffic data fusion method and system. The system includes: an OSPF message collecting module for acquiring network routing information of an OSPF; an OSPF topological stitching module for stitching a current network topology and sending the current network topology to an OSPF routing analyzing module; the OSPF routing analyzing module for acquiring network topology information of the whole network, correlating with the network topology information of the whole network through streams in the network, and acquiring source router information, destination router information and middle router information, combined with a CD algorithm; an ISIS message collecting module for collecting the message and acquiring network routing information of an ISIS; an ISIS topological stitching module for stitching the current network topology and sending the current network topology to the OSPF routing analyzing module; and an ISIS routing analyzing module for acquiring the network topology information of the whole network, correlating with the network topology information of the whole network through the streams in the network, and acquiring the source router information, the destination router information and the middle router information, combined with the CD algorithm.

Description

technical field [0001] The invention relates to the field of routing traffic data fusion, in particular to a method and system for OSPF and ISIS routing traffic data fusion. Background technique [0002] The OSPF routing protocol is a typical link-state routing protocol, which is generally used in the same routing domain. Here, the routing domain refers to an autonomous system (Autonomous System), namely AS, which refers to a group of A network that exchanges routing information with each other through a unified routing policy or routing protocol. In this AS, all OSPF routers maintain the same database describing the structure of this AS, which stores the status of the corresponding links in the routing domain. Information, the OSPF router calculates its OSPF routing table through this database. [0003] The IS-IS protocol is a routing protocol based on the link state algorithm, which means that a router as an intermediate system must fully know all other routers and their ...
