ABSTRACT:
A communication apparatus communicably connects a network of a plurality of apparatuses and a data relay apparatus to another network of the same manner as that of the network by detecting a failure occurring in the network, and determining a detour to assure communication between an apparatus connected to a network disconnected due to the failure detected and the other network. A tunneling is established serving as a virtual direct communication circuit to the determined detour.
