ABSTRACT:
A method for realizing many to many protection switching operation of ring network including: determining information of a switch request of M:N protection switching of the ring network, a destination node of the switch request, a source node of the switch request, a flag of long or short path, a status of bridging and switching, a channel number of protected working channel, and utilization condition of protection channels; carrying the information in a signaling and transferring it on the ring network; upon receipt of the signaling, performing the M:N protection switching of the ring network by a ring network node according to the information in the signaling. Therefore, the format of APS protocol signaling provided in this invention includes the information necessary for protection switching. This invention also provides an effective transmission approach of APS protocol signaling for protection switching.
