LOAD DISTRIBUTION SYSTEM, LOAD DISTRIBUTION DEVICE, LOAD DISTRIBUTION METHOD AND LOAD DISTRIBUTION PROGRAM

摘要

PROBLEM TO BE SOLVED: To achieve load distribution which is nicely interlocked with a virtual network while suppressing a cost burden.

SOLUTION: A server 0 functioning as a load distribution device among a plurality of servers 0-4 in a data center performs the steps of: acquiring all pairs of private addresses which have a same VLANID associated with global addresses which match transfer destination IP addresses of request packets, and MAC addresses which are assigned to communication apparatuses of other servers; determining a distribution destination of the request packets from among the acquired pairs of private addresses and MAC addresses on the basis of distribution algorithm; and setting a pair of a private address and a MAC address determined as the distribution destination and the VLANID as flow information for performing transfer control of the request packets, to a flow table of an open flow switch 110.
