Abstract:
1. A traffic distribution device used in a way that connects to a 0-th network, a first network including one or more servers and to a second network connected to said first network and including M-pieces of high-order layer processing devices associated with 0 through M-1, comprising: first packet relay means translating, each time a packet in which a predetermined destination IP address is set, is received from said 0-th network, this packet into a packet in which a destination MAC address is set as a first network sided MAC address of said high-order layer processing device, which MAC address is associated with a remainder value obtained by dividing a source IP address of the packet by M, and transmitting this packet onto said first network; and second packet relay means translating, each time the packet is received from said second network, this packet into a packet in which a destination MAC address is a second network sided MAC address of said high-order layer processing device, which MAC address is associated with a remainder value obtained by dividing the destination IP address of the packet by M, and transmitting this packet onto said second network.
