Abstract:
In a communication system, when a path is switched along with communication apparatus switchover, a packet sent/received via this path may be lost. A communication apparatus according to the present invention is characterized by including: a first means capable of operating a first network node on a virtual machine; and a second means capable of forwarding a control signal for terminating communication performed via a communication session established between the first network node and a third network node, to a virtual machine operating a second network node, in response to switchover from the first network node to the second network node corresponding to the first network node.
