Abstract
According an aspect of the embodiment, there is provided a method for accommodating signal paths to a ring network. A demand chain is defined as a series of traffic demands in which each traffic demand shares one of the pair of terminal nodes pointed thereby with at least one adjacent traffic demand and the number of pairs of terminal nodes pointed by traffic demands in the series of traffic demands is maximized. Each traffic demand of the demand chain is corresponded to a demand accommodating route which is defined as a route between the pair of terminal nodes on the ring network pointed by the each traffic demand and arranged in a predetermined rotation direction on the ring network. Then, signal paths required by traffic demands each pointing a pair of terminal nodes both included in the demand accommodating route chain are accommodated to the demand accommodating route chain.
