Abstract

At each network node, a packet classification unit makes a judgement to transfer only a packet necessary to be processed by software to a packet processing program processor and transfer other packets directly to a routing processor. Processing history information indicating the process history executed at each network node on a network route is transferred to the other network nodes so that other network nodes can store the processing history information in respective processing history repository table. Each node refers to this table and further transfers only the packet necessary to be processed by software to the packet processing processor.
