Method for searching multiple path of virtual container signals in similar CLOS network

摘要

The present invention is a first step to determine whether there is an existing route exists by searching for the input channel information of the switch included in the first stage and; Case if the existing route identified not by said first phase signal hierarchy by signal hierarchy type determination step and the signal hierarchy type determination step of determining the type of the next signal hierarchy is determined by the one-way connection is to be determined by VC3 VC3 VC3 route search step and the signal hierarchy type case by the determination step signal hierarchy is to be determined by the VC11 / VC12 VC11 / VC12 VC11 / VC12 route search step of searching for the path with the VC3, and VC11 / VC12 path through the route and a second step of if the route search by the search step fails, relocating the VC11 / VC12 path and consists of a route re-searching step of re-search for VC3 paths connecting the channels that make up the path to the link; by the first stage old path is in a broadcasting connection determination step, and a second stage by stage in the determination step to determine the broadcast-type connection to the stage is broadcasting dial when viewed Signal VC3 route search in the VC3 route search step and the VC3 route search step of performing VC3 route search if it determines as the signal hierarchy determination step that determines the hierarchy, the signal hierarchy VC3 by the determination step the signal hierarchy if in this case, to fail VC11 / VC12 relocating the path, and if the signal hierarchy identified as VC11 / VC12 by the re-search step, and a determination signal hierarchy step of re-search for VC3 route VC11 to navigate the VC11 / VC12 path / VC12 path search step and, to schedule page is comprised of a channel changing step of setting a route to the final destination channel from the Mid 2 stage channel if it determines a three-stage connecting channel forms a path in the link by the determination step the broadcast-type connection the complex provides a path search method of a virtual container signals in similar closed network of three steps.; The present invention as described above is to be able to efficiently perform the cross-connection and management by searching the composite path of the virtual container signal from the network, or similar closed-closed network that is capable of performing switching of the various hierarchy signal.
