| 摘要 |
The present invention discloses a method for assigning and processing a label in an optical network, an optical communication device, and an optical communication system, capable of assigning labels for an OTN network supporting different signal types and tributary slot types. The method includes: learning that a label switched path is required to be established in an optical network; generating a label according to a signal type of the label switched path and network resources, in which the label is used for indicating that a first optical channel data unit is multiplexed to a second optical channel data unit; the label includes a tributary slot type indication field that is used for indicating a tributary slot type of the second optical channel data unit, and the label further includes a tributary slot assignment indication field that is used for indicating a tributary slot occupied in the second optical channel data unit into which the first optical channel data unit is multiplexed; and sending the label to a node on the label switched path by a signaling message of General Multi-Protocol Label Switching. The present invention further provides a corresponding optical communication device and optical communication system. |
