Dynamic service flow classification and mapping method and optical network terminal and optical insertion network

Abstract

A method for dynamically classifying and mapping service stream includes holding service quality parameter of different service streams in integrated control unit, down-sending said parameter of service stream appointed with user and link position information of service function module to optical line terminal by said control unit, preparing a classifying and mapping policy as well as dispatchingpolicy of service stream by optical line terminal according to said parameter and information then sending said policies to optical network terminal of optical access network to carry out classifyingand mapping as well as dispatching operation there based on said policies.

Description

technical field [0001] The invention relates to the technical field of optical networks, in particular to a dynamic service flow classification and mapping method, an optical network terminal and an optical access network 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). Passive Optical Network (PON, Passive Optical Network) is an implementation technology of optical access network. PON technology is an optical access technology for point-to-multipoint transmission, 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, Optical Network Unit), wherein: [0003] OLT: Pro...

Problems solved by technology

[0012] As mentioned above, the service type of each type of service flow in the prior art corresponds to the OMCI management entity, and different OMCI management entities are used to manage the classification, mapping and T-CONT scheduling of service flows, which limits the upgrading of services and the deployment of new services. The main disadvantages are:

[0015] 3. When providing new services, it is necessary to expand the OMCI management entity, which will eventually lead to more and more complex ONT software and hardware;

[0016] 4. Difficulty in the intercommunication between OLT and ONT of different equipment manufacturers
