IRSR: Recover Inter-Domain Routing System from a Higher View Beyond Internet

Nowadays security situation of Internet is getting surprisingly worse. Many studies show that under the intensive paralyzing attack, inter-domain routing system which acts as the critical infrastructure of Internet, will falls into large-scale and long-term failure both of the routing nodes and links, endangering the running performance of Internet. Based on the centralized control theory, IRSR model proposed here builds an independent Decision Center above the existing inter-domain routing system, it could provide global situation awareness by using the sensor networks and controller networks deployed in each AS, and implements fast recovery from failures based on methods including pre-computed failover topology and consistent view. IRSR guarantees the maximum compatibility with existing routing protocols and structure of inter-domain routing system, which will reduce the deployment cost and complexity. Moreover, it also overcomes the problems like concealed AS information and long BGP convergence, which improves the recovery velocity and coverage rate.
