METHOD AND SYSTEM FOR COMMUNICATING OPTICAL TRAFFIC

摘要

PROBLEM TO BE SOLVED: To provide a method and system for communicating optical traffic that substantially eliminates or reduces at least some of the disadvantages and problems associated with conventional methods and systems.

SOLUTION: A method for communicating optical traffic includes the stages of adding optical traffic to an optical ring comprising a plurality of nodes and of communicating the optical traffic on the optical ring. The optical traffic comprises a plurality of virtual waveband which comprise a first virtual waveband of traffic comprising a first number of wavelengths and a second virtual waveband of traffic comprising a second number of wavelengths. The second number is different from the first number. The method also includes the stages of dropping the first virtual waveband of traffic at a first node of the plurality of nodes and of dropping the second virtual waveband of traffic at a second node of the plurality of nodes.
