A METHOD FOR TRANSMITTING MULTI-PROTOCOL LABEL SWITCH PROTOCOL DATA UNIT

摘要

The invention relates to a method for transmitting High-level Protocol data unit based on Low-level Protocol. It discloses a method for transmitting Multi-Protocol Label Switch protocol data unit, which can enhance the transmission efficiency, resource utilization, and network performance of the service in MPLS networks. The method for transmitting Multi-Protocol Label Switch protocol data unit includes the following steps: A, filling the Multi-Protocol Label Switch protocol data unit to payload information area field of the General Framing Procedure data frame; B, transmitting the General Framing Procedure data frame to the destination node through the transmission network; C, extracting the Multi-Protocol Label Switch protocol data unit from the payload information Area field of the General Framing Procedure data frame at the destination node (Fig.3 (b)).
