A METHOD OF TRANSMITTING DATA SERVICE ON SYNCHRONOUS DIGITAL NETWORK

摘要

A method for data traffic transmission on a synchronous digital network to overcome the inefficiency of the data packet transmission on the synchronous digital network equipment. The method includes, adding a RPR processing module after Ethernet interface in the equipment; through the RPR processing module, an uplink Ethernet frame from Ethernet interface being mapped to a RPR frame; through LAPS/PPP/GFP protocol, the RPR frame being mapped into the payload of a synchronous digital network; the volume and number of the VCs and total bandwidth of the RPR being configurable. When the RPR frame arrives at the destination node of the RPR, it is stripped from the RPR and recovered to its original Ethernet frame. The method and device transmit data service efficiently, and the total bandwidth of the RPR is adjustable and is statistically multiplexed.
