A symmetrical capacity network may be adapted to accommodate asymmetrical
network traffic patterns by deploying Protected Dedicated Wavelengths
(PDWs) between one or more head-end nodes and the access nodes on a
ring-based topology network. The PDWs include pairs of wavelengths
extending in opposite directions around the fibers forming the original
ring and terminating at the intended access node. The pairs of
wavelengths form unidirectional working and protection paths from the
head-end node to the intended access nodes. By deploying the symmetric
capacity and asymmetric capacity on the same platform within the head-end
node, it is possible to apply policy across the network resources to
allow traffic flows to be selectively placed on the most appropriate
network resource.
