COMPUTER SYSTEM, SERVER, OPENFLOW CONTROLLER, AND COMMUNICATION METHOD

摘要

In a computer system according to the present invention, a host sends a packet in which protocol information above a TCP layer and within a transport layer is included in an option area of a TCP header. An open flow controller set a flow entry wich defines a forwarding destination corresponding to the protocol information, in a switch. An open flow switch forwards the received packet toward a forwarding destination which corresponds to the protocol information included in the TCP header of the received packed. As a result, an adaptation of the computer system is increased.
