Abstract

The invention discloses a service bearing method for G bit passive optical network system comprising following steps: 1) when optical network unit receives uplink service data stream from user side, separately marking virtual LAN label of the data stream, adapting the service data stream of different virtual LAN label to adapting port of G bit passive optical network GPON, transmitting to optical line terminal; 2) the optical line terminal restores packaged data stream of different virtual LAN label from the GPON package port, mapping the data stream of different virtual LAN label to virtual LAN of different HSP for package to implements service bearing of G bit passive optical network system. The invention provides a method for solving service bearing in GPON access technology.

Description

technical field [0001] The present invention relates to a wired broadband access communication system using GPON (Gigabit Passive Optical Network, G-bit Passive Optical Network) technology, in particular to a method for carrying services in the GPON system. Background technique [0002] In recent years, broadband networks have developed rapidly, and various high-bandwidth services and applications have emerged continuously, making the deployment of DSLAM (Digital Subscriber Line Access Multiplexer) tend to be dispersed and moved down, sufficiently close to users to improve higher bandwidth and higher quality broadband access services. With the rapid development of optical fiber access technology, technologies such as GPON and EPON (Ethernet Passive Optical Network, Ethernet Passive Optical Network) are becoming more and more mature. Although in the long run, optical access technology has the advantages of long-distance symmetrical high-speed FTTH) is an ideal broadband acce...
