Multicast MPLS table and label registration method of point-to-point MPLS multicast table and table search method of multicast MPLS node table and how to delete a multicast MPLS node table and additional registration method of multicast MPLS node table and initial registration method of multicast MPLS node table operation method of multicast MPLS node labels and search method of point-to-point

摘要

PROBLEM TO BE SOLVED: To enable tables to be improved in memory using efficiency so as to shorten a retrieval time in the methods of forming, initially registering, additionally registering, removing, and retrieving the tables of multicast MPLS nodes.;SOLUTION: An input label table which relates a single input label with storage position information on an output label, and an output label table which relates storage position information on the output labels with each other, are constituted in a point-to-point label exchange where a single input label is set correspondent to a plurality of output labels; and initial register processing, additional register processing, removal processing, and retrieval processing are carried out by the use of the input label table and the output table.;COPYRIGHT: (C)2005,JPO&NCIPI
