Abstract
Methods and devices for constructing a label and forwarding a label packet are provided. A node receives a message which carries a segment list and a segment list Identifier (ID) for identifying the segment list. The node constructs a label forwarding table according to the segment list and the segment list ID, and performs forwarding according to the label forwarding table; and/or the node maintains a mapping relationship between the segment list and the segment list ID.
Claims37
A method for constructing a label and forwarding a label packet, comprising:
- receiving, by a node, a message which carries a segment list and a segment list Identifier (ID) for identifying the segment list;
- constructing, by the node, a label forwarding table according to the segment list and the segment list ID, and performing forwarding according to the label forwarding table;
- and/or, maintaining, by the node, a mapping relationship between the segment list and the segment list ID.

A device for constructing a label and forwarding a label packet, which is applied to a node and comprises a hardware processor arranged to execute program modules comprising:
- a first receiving module, configured to receive a message which carries a segment list and a segment list Identifier (ID) for identifying the segment list;
- and
- a constructing module, configured to construct a label forwarding table according to the segment list and the segment list ID, and perform forwarding according to the label forwarding table;
- and/or, the constructing module is configured to maintain a mapping relationship between the segment list and the segment list ID.

A device for constructing a label and forwarding a label packet, which is applied to a controller and comprises a hardware processor arranged to execute program modules comprising:
- a first sending module, configured to send a message to a node, wherein the message carries a segment list and a segment list Identifier (ID) for identifying the segment list, and the segment list and the segment list ID are used for indicating the node to construct a label forwarding table and perform forwarding according to the label forwarding table;
- and/or, the segment list and the segment list ID are used for indicating the node to maintain a mapping relationship between the segment list and the segment list ID.

A device for constructing a label and forwarding a label packet, which is applied to an ingress node and comprises a hardware processor arranged to execute program modules comprising:
- a third receiving module, configured to receive a message sent by a controller, wherein the message carries a segment list and a segment list Identifier (ID) for identifying the segment list;
- and
- a third sending module, configured to send the message to a node, wherein the message is used for indicating the node to construct a label forwarding table and perform forwarding according to the label forwarding table;
- and/or, the message is used for indicating the node to maintain a mapping relationship between the segment list and the segment list ID.
