Problems solved by technology

[0053] The technical problem to be solved by the present invention is to provide a method for mapping service flows to service transmission channels in a passive optical network system, which overcomes that the service flow mapping method in the prior art does not support the DSCP domain of the VLAN ID, IP layer, and IP Or the MAC source address, IP or MAC destination address, protocol type, TCP / UDP port number or other characteristics of the message map the service flow to different service transmission channels, so it cannot meet the shortcomings of the subdivided service QOS requirements

Embodiment Construction

[0073] Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:

[0074] The message feature is the value of a certain feature field in the message data frame. For example, for the IP address 10.11.1.1, the value of the message feature is 4 bytes (00001010, 00001011, 00000001, 00000001). The packet characteristic offset byte number is the offset byte number of the packet characteristic field from the packet (data frame) header, for example, the offset byte number of the source IP address field from the Ethernet packet header is 26.

[0075] In order to overcome the disadvantage that the existing technology cannot support the mapping of service flows according to the message characteristics of different services, the present invention first determines the message characteristics of different services and the number of offset bytes of the message characteristics, and saves them in the optical network terminal , for examp...

Abstract

The invention provides a method for mapping the traffic flow to the operation transmission channel, including: mapping the operation flow to the operation transmission channel according to message characteristic of the operation flow after the optical network terminal receives the operation flow, wherein the message characteristic is VLAN ID or DSCP domain. Accordingly, the invention also provides an optical network terminal comprising a traffic flow mapping module used for mapping the traffic flow which accords with the message characteristic in the traffic flow received in the optical network terminal to the operation transmission channel, wherein the message characteristic is VLAN ID or DSCP domain. The invention can map the traffic flow to different GEM PORT according to VLAN ID, DSCP domain, IP or MAC source address, IP or MAC destination address, the protocol type, the TCP/UDP port number ot other characteristic of the message, which ensures the requirement to subdivide the operation QOS.

Description

technical field [0001] The invention relates to the technical field of optical networks, in particular to a method for mapping service flows to service transmission channels and an optical network terminal in the technical field. Background technique [0002] The current broadband access technology is mainly divided into copper wire access technology and optical access technology. An access network implemented by an optical access technology is called an optical access network (OAN, optical access network). PON is an implementation technology of optical access network. PON technology is a point-to-multipoint optical access technology, such as figure 1 As shown, the PON system consists of an optical line terminal (OLT, Optical Line Terminal), an optical distribution network (ODN, Optical Distribute Network), and an optical network unit (ONU, OpticalNetwork Unit), wherein: [0003] OLT: Provides a network side interface (SNI, Service Node Interface) for the OAN, and connects...
