Embodiment Construction

[0029] Aiming at the problems existing in the prior art, the present invention proposes a method and system for BGP routing flow data fusion, the method comprising:

[0030] Step 1, analyze and save the mandatory information and some optional information contained in the BGP message information (including source IP, source mask, destination IP and destination mask), and declare the BGP vector routing information according to different network segments Store in the BGP information set; analyze and store the fifth type of LSA information, and store all information of the fifth type of LSA information in the fifth type of LSA information set according to different link state ID information;

[0031] Step 2, obtain the flow information of the BGP route, and process the flow information according to the information in the BGP information set and the fifth type LSA information set, and analyze the domain flow and the flow through the domain , if there is only one AS boundary router ...

Abstract

The invention provides a method and a system for fusing BGP route traffic data and relates to the field of route traffic data fusion. The method comprises the steps as follows: analyzing and storing required information and partial selectable information contained in BGP message information, and storing BGP vector property routing information in a BGP information set according to different declared network segments; analyzing and storing the type 5 LSA information and storing all information of the type 5 LSA information in a type 5 LSA information set according to different link state ID information; obtaining flow information of a BGP route and processing the flow information according to the information in the BGP information set and the type 5 LSA information set, and using an AS edge router as a target router of the AS corresponding to the flow if the AS and the next hop AS only have one AS edge router while analyzing the flow leaving the domain or the flow flowing through the domain.

Description

technical field [0001] The invention relates to the field of routing traffic data fusion, in particular to a method and system for BGP routing traffic data fusion. Background technique [0002] BGP (Border Gateway Protocol, Border Gateway Protocol) is a core decentralized autonomous routing protocol on the Internet. It achieves reachability between autonomous systems (AS) by maintaining IP routing tables or 'prefix' tables, and is a vector routing protocol. BGP does not use traditional Interior Gateway Protocol (IGP) indicators, but uses paths, network policies, or rule sets to determine routes. Therefore, it is more appropriately called a vectoring protocol than a routing protocol. BGP is an autonomous system vector routing protocol running on TCP. BGP is the only protocol designed to handle networks the size of the Internet, and it is also the only protocol that can properly handle multiple connections between unrelated routing domains. [0003] The main function of th...
