Abstract: A control method of a system supporting fault tolerance is provided, at first, a first host executes a transmission control protocol agent to receive a data stream from a client device. Then the TCP agent transmits an acknowledgement packet to the client device in response to the data stream from the client device. Then the TCP agent determines whether a fault tolerance mechanism of the virtual machine is activated. When the TCP agent determines that the fault tolerance mechanism of the virtual machine is activated, the TCP agent determines whether the virtual machine operates in a running state. When the TCP agent determines that the virtual machine is not in the running state, the TCP agent temporarily storing the data stream. When the TCP agent determines that the virtual machine operates in a running state, the TCP agent transmits the data stream to the virtual machine.
