<P>PROBLEM TO BE SOLVED: To commonly use sub-bands, and increase a network capacity. <P>SOLUTION: A method to transport traffic on an optical ring includes a step of splitting an incoming signal (including traffics in a plurality of sub-bands) into a first signal and a second signal at one or more nodes coupled to the optical ring. The first signal includes the traffic in a first sub-band of traffic channels and the second signal includes the traffic in the second sub-bands of traffic channels of the incoming signal. The method also includes a step of receiving the traffic in the first sub-band at a bypass element, rejecting the traffic in a first portion of the first sub-band at a bypass element, and forwarding the traffic in a second portion of the first sub-band at the bypass element. In addition the method includes a step of combining the traffic in the second signal with the traffic in the second portion of the first sub-band for transport on the network. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
