電気通信網における方法及び装置
Document Type and Number:
Japanese Patent JP5788954
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a multi-protocol label switching (MPLS) node.SOLUTION: A context descriptor is defined for each frame received on a connection terminated at the node, and this context descriptor is provided together with the frame to a corresponding function (e.g. Operations, Administration and Maintenance, OAM) if needed. The context descriptor is constructed on the basis of key attributes characterizing the terminated connection, over which the frame is received, and addresses a particular function endpoint (Maintenance Endpoints (MEPs), Selector Bridge of a protection instance etc.) of a corresponding function (OAM, protection, etc.). In one embodiment, the MPLS node is directed to check not only the first label but also the second label, and not to drop the first label (and the label space if relevant) when the second label is the Generic Association Channel Label (GAL).
