Problems solved by technology

[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

Abstract

The invention provides a cross-domain border gateway protocol (BGP) policy adjustment and control effect estimation method and a cross-domain BGP policy adjustment and control effect estimation device VTGCS. An independent VTGCS allocated in each autonomous system is interconnected with a core component BGN of a BGP-Grid at the autonomous system to automatically generate, intercept, capture and process a virtual flow data packet as required; and the virtual flow data packet is processed and forwarded through the BGN of the autonomous system and the BGN of other related autonomous systems, so that the simulation and the estimation of the adjustment effect of an inter-domain interconnection routing policy of a real internet are finished together.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a cross-domain BGP policy control effect evaluation method and device VTGCS. 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 the exchange of routing information between domains , 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. Therefor...
