Transmission system, routing control device and method for controlling routing

摘要

A first terminal-side routing control device 13 is placed between a first communication network 21 and a first communication terminal 11. A second terminal-side routing control device 15 is placed between a second communication network 22 and a second communication terminal 12. The first terminal-side routing control device 13 includes a first via information setting unit 14 for including, in data received from the first communication terminal 11, information for specifying a routing control device 33 placed on one side of a long-distance transmission path 23 as a via device. The second terminal-side routing control device 15 includes a second via information setting unit 16 for including, in data received from the second communication terminal 12, via information for specifying a routing control device 34 placed on the other side of the long-distance transmission path 23 as a via device.

1. A transmission system comprising:
a first communication terminal and a second communication terminal that perform bidirectional communication communicably connected via a first communication network, a long-distance transmission path, and a second communication network; and protocol converters and routing control devices on both sides of the long-distance transmission path,
wherein a first terminal-side routing control device is placed between the first communication network and the first communication terminal,wherein a second terminal-side routing control device is placed between the second communication network and the second communication terminal,wherein the first terminal-side routing control device comprises a first via information setting unit for adding, to data received from the first communication terminal, information for specifying a routing control device placed on one side of the long-distance transmission path as a via device and a first transmission unit for transmitting the data including the information to a routing control device specified by the information via the first communication network, andwherein the second terminal-side routing control device comprises a second via information setting unit for adding, to data received from the second communication terminal, via information for specifying a routing control device placed on an other side of the long-distance transmission path as a via device and a second transmission unit for transmitting the data including the via information to a routing control device specified by the via information via the second communication network.
