Patent ID: 8238365

Claim:
A device for supporting optical transport network service dispatch in an optical synchronization network, comprising service cards, a backplane interface and a plurality of dispatch units, wherein: the service cards are used to process and distribute service signals, and each service card includes a service signal processing module to process the service signals and a service signal distribution unit to distribute the service signals to different backplane routings of the backplane interface, wherein the service signal distribution unit is configured to adjust a number of the service signals from the service signal distribution unit to the backplane interface according to different bandwidths of the service signals; the backplane interface is used to receive the service signals distributed by the service cards through the backplane routings, and send the service signals to the dispatch units; the dispatch units are connected with each service card through the backplane interface to dispatch the service signals, wherein the number of the dispatch units connected with the service cards can be linearly increased according to the different bandwidths of the service signals and the increased number of the dispatch units connected with the service cards is relevant to the maximum bandwidths of the service cards.
