ABSTRACT:
Disclosed is a communication control method for recovering communication failures caused by a packet loop that occurs as a result of L2-level misconnection at relay switches in a communication system where data transmission/reception is carried out between a plurality of end hosts connected to the relay switches within a subnet. The method includes the steps of consecutively sending packets each having, as its originator address, a MAC address other than an originator MAC address of an end host desired to be communicated making up the subnet; thereby stopping the packet loop; and then sending packet data using, as a destination MAC address, a MAC address of a destination end host.
