<p>PROBLEM TO BE SOLVED: To prevent the overflow of a reception queue and to keep the routing performance by making a reception driver transfer its received packet to a protocol processing part via a scheduler, when the packet is addressed to the driver itself or transfer the received packet directly to the protocol processing part by a function call, when the packet is not addressed to the driver itself. SOLUTION: A router 10 receives a packet from a network 181 via a reception driver 161 and sends it to a packet distribution part 151 of a routing control part 15. The part 151 decides whether the packet is addressed to the router 10 by the address of the packet destination. When the packet is addressed to the router 10, the part 151 selects a method of transfer ring the packet to a protocol processing part 12 via a scheduler 13. When the packet is not addressed to the router 10 and when a fragment flag 152 exists, the packet is transferred to the part 12 via the scheduler 13. Thus, the load applied to the router 10 due to the packet, that is not addressed to the router 10 itself, can be prevented.</p> |
