Network switch, network switch control method, and a network switch control program

摘要

PROBLEM TO BE SOLVED: To provide a network switch which avoids congestion in a control interface while allowing load sharing by means of a plurality of switches constituting a multi-chassis, and to provide a network switch control program and a network switch control method for controlling the network switch.;SOLUTION: When a switch 2000 cannot communicate with a transmission source node 10 or a transmission destination node 20 in a combination of "the transmission source node 10, the transmission destination node 20" where the switch itself is relaying a packet, the switch 2000 relaying a packet is changed. As a switch 2000 for relaying a packet being transmitted between the combinations anew, a switch 2000 which can communicate with both of the transmission source node 10 and transmission destination node 20, without going through another switch 2000, is selected.;COPYRIGHT: (C)2014,JPO&INPIT
