Abstract: A method for transmitting high-level PDUs (Protocol Data Units) over low-level protocol and method for transmitting MPLS (Multi-protocol Label Switch) PDUs so as to improve transmission efficiency, resource utilization, and network performance of MPLS network traffics. The method for transmitting MPLS PDUs includes the following steps: A. adding the pending MPLS PDU to PIA (Payload Information Area) field of a GFP (General Framing Procedure) data frame; B. transmitting the GFP data frame to the destination node via a transmission network; C. retrieving the MPLS PDU from the PIA field of the GFP data frame at destination node.

Abstract: The present invention relates to PWE3-based communication and discloses a method of implementing PWE3 protocol, with the aim to implement PWE3 architecture over RPR-based MPLS PSN, provide protection and bandwidth sharing capability, and improve quality and efficiency of PWE3 architecture. Said method of implementing PWE3 protocol comprises the following steps: A. Encapsulate data frame on said PWE3 PSN layer into RPR data frame; B. Transmit said RPR data frame to the destination node through RPR; C. Decapsulate said RPR data frame into PSN layer data frame at said destination node.
