Abstract:
1. A method for implementing services on a network element based on multiple IDs, wherein the method comprises steps of: a network element setting an ID corresponding to a new service in local as an active ID; the network element advertising an ID information including the newly set active ID over the network by a routing protocol; each adjacent network element which is connected with the network element via a Traffic Engineering (TE) link acquiring the newly set active ID, setting the newly set active ID as its new opposite-end active ID of the TE link, and advertising over the network a link information which contains the new opposite-end active ID and its current active ID; and when implementing the new service on the network, calculating paths based on the new active ID, and implementing the new service according to the calculation result, wherein before the step of a network element setting an ID corresponding to a new service in local as an active ID, the method further comprises the step of: creating multiple loop-back interfaces in advance on control planes of the network elements, setting a network-layer ID on each of the loop-back interfaces, and setting each of the network-layer IDs on transmission planes.
