Title:
ネットワーク中継装置およびパケット振り分け方法
Document Type and Number:
Japanese Patent JP5028431
Kind Code:
B2
Abstract:
The present invention provides a network relay apparatus capable of assuring the prevention of occurrence of order reversion of packets within flows and shifting a packet distribution destination according to load information. The network relay apparatus includes: a packet distribution processor for distributing input packets to thereby achieve load dispersion of packet processing; a statistical information collector for regularly collecting load conditions of respective packet processors; and a distribution information holder for retaining information for specifying the packet distribution destinations upon distribution of the packets. Information about the load conditions of the respective packet processors are compiled and distributed to the packet processor smallest in load. Timing provided to change the packet distribution destination is assumed to be given when a processing waiting queue does not include a packet corresponding to its flow.
