Patent abstract
The hierarchical packet processing system comprises a relay unit and a server, which relay received packets. The relay unit comprises a call unit for calling up a prescribed service processing unit for performing the service process of a received packet, a first service processing unit for performing the service process of the received packet by the call of the call unit, a second service processing unit for performing a virtual service process of the received packet by the call of the call unit. The server comprises an external service processing unit for performing the arbitrary service process of the received packet instead of the second service processing unit when the call unit calls up the second service processing unit.
