Internet protocol transmission network node, has two interfaces for bidirectional link and unidirectional link, respectively, and load sharing unit provided for data transmission between two interfaces of bidirectional links

摘要

The node has two interfaces (12, 16) for bidirectional link (14) and unidirectional link (18), respectively. A link is provided between a third interface (22) of the bidirectional link and the interface (16). A tunnel is provided between the interface (22) and another interface (12). A load sharing unit (34) is provided for data transmission between the interfaces (12, 22) of the bidirectional links. Independent claims are also included for the following: (A) a communication system of a data transmission network comprising a node (B) a dimensioning process and optimal use of a connection between the nodes.
