ABSTRACT:
A communication scheme assigns address and determines the setting of address servers. In this scheme other communication devices are prohibited to transmit an address initialization request for a prescribed period of time since one communication device transmitted the address initialization request for an address managed by a control protocol, so that conflict of the initialization requests for the same address will not occur and the problem of assigning the address in overlap to the communication devices will not arise. Also, other communication devices are prohibited to transmit an address server detection request packet for a prescribed period of time since one communication device transmitted the address server detection request packet, so that the conflict on the network by a plurality of address server detection requests will not occur, and it is possible to determine the MAC address server uniquely.
