- Abstract
- A method for switching a communication channel in a shared memory communication environment which sets up a TCP/IP (Transmission Control Protocol/Internet Protocol) communication channel and a shared memory communication channel from a first virtual machine to a second virtual machine, the method includes: transmitting a channel switching message to the first virtual machine when the first virtual machine moves to another physical machine; transmitting the channel switching message from the first virtual machine to the second virtual machine; and switching a channel state between the first virtual machine and the second virtual machine.
