Abstract

A method for mapping flow rate in passive optical network system includes configuring flow rate link of each user data stream to port then to virtual transmission container T-CONT, carrying flow rate link information in each user data stream, mapping received user data stream onto port in corresponding flow rate link first and then mapping received user data stream from port to T-CONT in flow rate link for sending out according to flow rate link information in user data stream after said user data stream is received optical fiber access terminal unit ONU / T.

Description

technical field

[0001] The invention relates to a service data processing technology in a passive optical network (PON) system, in particular to a traffic mapping method in a passive optical network (PON) system. Background technique

[0002] At present, the global backbone network has been completely fiber-optic, mainly using DWDM (Dense Wavelength Division Multiplexing) technology to increase the transmission bandwidth (2.5G ~ 10Tbps), the fiber growth rate of the metropolitan area network is increasing rapidly, and the density is close to saturation. Among them, the important technology There are SONET / SDH-Based Metro Optical Network (SONET / SDH-based Metro Optical Network), Metro WDM (Metro Wavelength Division Multiplexing) and Optical MetroEthernet (Ethernet Access to Optical Network), etc., with a bandwidth of about 2.5G per wavelength -> 10Gbps, while the mainstream Ethernet speed with the largest LAN share has gradually moved from 100Mbps to 1Gbps for optical fiber...
