Problems solved by technology

[0010]However, the G.984.3 protocol only gives a schematic diagram of the virtual pipe control mode, and does not clearly propose how to link the traffic determined by T-CONT and Port-ID Mapping with specific business to realize specific business makes this technology unable to be directly applied to actual business, hindering the promotion and development of this technology

Embodiment Construction

[0047] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0048] For the downlink data from the OLT to the ONU / T, it can be transmitted according to the G.984.3 protocol in the prior art, but the traffic mapping of the uplink service data cannot be realized according to the protocol, so the present invention is aimed at ONU / T to Traffic mapping for upstream data of the OLT.

[0049] The core of the traffic mapping method in this passive optical network system of the present invention is: configure the traffic link from each user data flow to Port and then to T-CONT in the user terminal equipment, and carry traffic in each user data flow Link information: After receiving the user data stream, the ONU / T first maps the received user data stream to the Port in the corresponding traffic link according to the traffi...

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...
