PACKET FORWARDING METHOD FOR REDUCING PACKET LOSS IN ROUTER

摘要

A method and an apparatus for reducing a packet forwarding delay in a router are provided to reduce delay or loss of a packet by having a local agent in a forwarding processor block and processing information between software blocks of a routing processor unit and a forwarding processor unit. A routing processor unit(110) checks a new routing entry to which a packet is to be forwarded, allocates a new connection identifier with respect to a next hop of the checked routing entry, and transfers information about the checked routing entry including the connection identifier. Forwarding processor units(120,130) allocate the new connection identifier through the information about the routing entry received from the routing processor unit, obtain a link layer address from the next hop and inform the routing processor unit, and forward the packet to the next hop according to the obtained link layer address.
