Cross-domain BGP routing policy deployment method

Abstract

The invention provides a cross-domain BGP routing policy deployment method. Through simulating the inter-domain interconnection relationship and the routing policy of a real internet, a network operator is provided with a platform for routing measurement and policy simulation; through acquiring the inter-domain interconnection performance parameters of the real internet, the network operator is provided with reference data for policy evaluation and routing optimization; through simulating the inter-domain flow guide of the real internet, the network operator is provided with a platform for inter-domain adjustment and control effect evaluation; and through the multilevel simulation of the inter-domain interconnection of the real internet, the network operator can conduct simulation and evaluation on a BGP-Grid platform system structure before the practical deployment of a policy adjustment and control scheme. Thereby, the adverse impact on a global internet caused by subjective or objective errors or omissions to some extent is avoided and the stability and the effectiveness of the overall operation of the global internet are improved.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a method for deploying cross-domain BGP routing policies. Background technique [0002] As an independent network complex, autonomous domains (Autonomous System) constitute the global Internet through mutual interconnection. The interconnection between autonomous domains mainly adopts the BGP (Border Gateway Protocol) routing protocol, which is a policy-based inter-domain routing protocol, through the deployment of routing policies to control inter-domain routing information Exchange, and then realize the guidance and orientation of cross-domain user data traffic. [0003] However, due to the relative independence of autonomous domains, each autonomous domain will define and deploy specific routing policies based on its own needs or regulations, and the routing policies within the autonomous domain are usually not disclosed to the public. Therefore, this will have an adverse e...

[0003] However, due to the relative independence of autonomous domains, each autonomous domain will define and deploy specific routing policies based on its own needs or regulations, and the routing policies within the autonomous domain are usually not disclosed to the public

Therefore, this will have an adverse effect on the cross-domain user data traffic arriving from or passing through this autonomous domain from other autonomous domains, making it impossible to reach the destination network according to the optimized (or expected) path, and due to the non-transparency of the routing policy , which also makes it difficult to realize the coordinated regulation of inter-domain routing policies, thereby reducing the forwarding efficiency of cross-domain user data traffic and affecting the overall operating performance of the global Internet

In addition, in the deployment and implementation of routing policies, due to the large scope of influence of routing policies, a small error or omission (caused by human factors or non-transparency of policies) will often cause large-scale routing problems, resulting in more serious consequences
