PATH SETTING METHOD, COMMUNICATION DEVICE AND STORAGE MEDIUM

摘要

PROBLEM TO BE SOLVED: To set a shortcut path at high speed by simplifying a necessary processing by including a step to set the shortcut path between a device at a transmission origin and a device at a destination by using a signaling message of a signaling protocol. SOLUTION: A step to dissolve address information to set the shortcut path between the device at the transmission origin and the device at the destination by using the signaling message of the signaling protocol is uncluded in a communication device. In this case, the address information of an edge device as the origin of data transmission is informed to a final destination edge device by displaying the address information on the signaling message and mapping the address information on a new signaling message to be generated by a router. Thus, a processing of the signaling message in each LAN is by-passed and the shortcut path is simultaneously set from the edge device at the destination to the edge device at the transmission origin.
