Summary :

A parallel IP router that uses off-the-shelf wor-kstations and interconnecting switches is presented. This router, called CORErouter-I, is a medium-grained, functionally distributed parallel system consisting of four kinds of processors for routing, routing-table searching, servicing, and line interfacing. Also discussed are issues related to the implementation of CORErouter-I, especially in terms of routing protocol processing and packet-forwarding. Performance characteristics of CORErouter-I are also clarified through several experiments performed to evaluate maximum throughput, analyze packet-forwarding time, and estimate the effect of parallel processing on the route-flapping problem.
