Title:
PACKET PROCESSING SYSTEM, PACKET PROCESSING METHOD AND PROGRAM
Document Type and Number:
Japanese Patent JP2007325171
Kind Code:
A
Abstract:

To provide a low-cost packet processing system capable of suppressing the number of packets in a standby state for processing due to congestion without requiring a large-capacity buffer.

A plurality of transfer devices 1 and a shared transfer device 2 are mutually connected via a switch 3. Each of the transfer devices 1 receives a packet provided with header information including information about a destination from a network connected to its own device, and transfers the received packet to the destination transfer device connected to the network on the basis of the header information. When a load of the transfer device 1 of the transfer source is transferred from a low load state to a high load state, the shared transfer device 2 processes reception packets which cannot be processed by the transfer device 1 of the transfer source, instead of the transfer device 1 of the transfer source.
