TUNNEL SWITCHING METHOD AND SYSTEM FOR MULTI-PROTOCOL LABEL SWITCHING SERVICES

摘要

FIELD: radio engineering, communication.;SUBSTANCE: invention relates to a tunnel switching method for multi-protocol label switching (MPLS) services. The method includes steps of: mapping output port information of multiple MPLS services which use the same working tunnel to a link aggregation control protocol (LACP) port; setting items of next hop information to which the MPLS services correspond as multiplexed items; and when tunnel switching is needed, updating the items of the next hop information and setting of the LACP port.;EFFECT: reducing the service switching time of the MPLS, as a result of which the number of services has no influence on the switching time, and a lot of hardware resources are saved.;10 cl, 3 dwg
