Claim:
1. A communication method comprising: when a first communication packet transmitted from a first terminal which is deployed in a second physical machine group and included in a first segment is received, storing, by a second network device, identification information of the first communication packet transmitted from the first terminal, the second network device being included in a second information processing system that is constructed based on configuration information of a first information processing system including a first network device and that is provided across a first physical machine group in which the first network device is deployed and the second physical machine group in which the second network device not included in the first information processing system is deployed; first transmitting, by the second network device, the first communication packet transmitted from the first terminal to the first network device based on path information included in the configuration information when the first communication packet transmitted from the first terminal is a communication packet to a second terminal included in a second segment; when the first communication packet is transmitted from the first network device, second transmitting, by the second network device, the received first communication packet transmitted from the first network device to the second terminal and updating, by the second network device, the path information so as to transmit a communication packet transmitted from the first terminal without passing through the first network device; and performing, by the second network device, transmission based on the updated path information when a communication packet transmitted from the first terminal to the second terminal is received.
