Ownership transfer of a label switched path

摘要

Control of a label switched path established in a network is transferred between a management plane and a control plane of the network. A node (e.g., node C) receives a message indicating a change in control of the label switched path, the message identifying the label switched path by a cross-connection identifier corresponding to an entry in the control data stored at the node which identifies data plane ingress and egress segments cross-connected at the node. Control data at the node is updated based on the identified label switched path. The message includes a list of cross-connection identifiers for nodes (e.g., nodes C, E, and F) along the label switched path. The cross-connection identifier can be an mplsXCIndex.

1. A method of configuring a change in control of a label switched path established at a node of a network, the change in control being from a management plane to a control plane of the network, the node storing control data, the method comprising the steps of:
receiving a message indicating a change in control of the label switched path, the message identifying the label switched path by a cross-connection identifier corresponding to an entry in the control data stored at the node which identifies data plane ingress and egress segments cross-connected at the node; and updating control data at the node based on the identified label switched path, wherein the control data stored at the node comprises a first management information base which is used by the data plane and a second management information base which is used by the control plane, and wherein the updating comprises,
creating an entry in the second management information base;associating the entry in the second management information base with an entry in the first management information base which identifies data plane ingress and egress segments cross-connected at the node.
