Abstract(in English) | IP networks would become public communication infrastructures. An IP router is now expected to possess higher reliability on its packets processing and higher availability on its oeprating. In this paper, to improve the router availability, we propose the stateful redundant routing management modules, which are loaded on a modularized router composed of several separated entities. According to the proposal, we introduce our highly available OSPF implementation. We deploy routing process for each routing management module on the router. The routing processes on the modules compose a redundant OSPF control system that makes the IP router highly available against internal router failure. At a routing process failure on a primary module, a backup process takes over the state of network interfaces and the information of OSPF routing protocol. The redundant OSPF control system continuously processes routing protocol with neighbor routers. |
