Abstract

The IP packets from a source are suitably forwarded by the routers along the path(s) to the destination. The packets destined to the routers themselves are called non-forwarding packets, and their processing is crucial to the overall speed of IP routers. An architecture is proposed here for efficiently handling the non-forwarding packets for high-speed routers. This architecture includes the Inter-Processor Communication Message Protocol for internal communication needed within the router for distributed processing of the non-forwarded packets. Our implementation results show that this architecture improves the processing speed by 10% as compared to the existing mechanism based on UDP/IP.
