REPRESENTATION OF THE PHYSICAL DEGRADATIONS IN AN OPTICAL COMMUNICATION NETWORK

摘要

In order to produce a representation of the physical degradations in an optical communication network comprising transparent switching nodes (1, 2, 3, 4) mutually connected via optical links (11, 12, 21, 22, 31, 32, 41, 42), the method comprises: combining a pair of contradirectional optical links into a bidirectional link (10, 20, 30, 40), providing at least one respective physical degradation parameter for each of said contradirectional optical links of said pair, determining at least one physical degradation parameter characteristic of said bidirectional link from said physical degradation parameters of the contradirectional optical links of said pair, and storing a descriptor of the bidirectional link comprising said at least one physical degradation parameter characteristic of said bidirectional link.
