A Rerouting Framework Against Routing Interruption for Secure Network Management

Abstract

In this paper, we consider the problem of routing interruption, which has received significant interest in recent years. To solve this problem, rerouting is an effective way. However, how to design an effective secure and applicable rerouting algorithm remains a significant challenge. To this end, we propose a fast rerouting framework for routing interruption. Our framework consists of two parts: (1) Diagnose routing interruption. We determine the location of interruption by directly interrogating the control plane IPv6 stack. (2) Implement fast rerouting. We propose the rerouting algorithm to make the router match and reroute all prefixes affected by interruptions. This paper updates the path only by adding a forwarding rule, thus the interruption recovery time is reduced. We conduct a comprehensive evaluation for our rerouting framework. Experimental results show that our method is better than FCP, OSPF and DLF in speed and accuracy.
