Abstract
A multi-service transport and receiving method and apparatus are provided. The method includes: obtaining mapping transport control information of M services; determining a mapping procedure of the M services; and mapping the M services to a variable optical payload unit according to the mapping procedure. Therefore, a transport solution can be flexibly customized based on a transport requirement of a client service, so that a data plane becomes programmable.
Claims20
A multi-service transport method, the method comprising:
- obtaining, by a device, mapping transport control information of M services, wherein mapping transport control information of each service of the M services carries a transport requirement of a respective service;
- determining, by the device, a mapping procedure for the M services based on the mapping transport control information of the M services, wherein the mapping procedure is used to map the M services to a variable optical payload unit by using a programmable tributary slot group frame, and the programmable tributary slot group frame is a tributary slot set used to meet transport requirements corresponding to the M services;
- and
- mapping, by the device, the M services to the variable optical payload unit according to the mapping procedure.
A multi-service transport apparatus comprising:
- a processor;
- and
- a memory configured to store instructions that, when executed by the processor, cause the processor to:
- obtain mapping transport control information of M services, wherein mapping transport control information of each service carries a transport requirement of a respective service;
- and
- determine a mapping procedure for the M services based on the mapping transport control information of the M services, wherein the mapping procedure is used to map the M services to a variable optical payload unit by using a programmable tributary slot group frame, and the programmable tributary slot group frame is a tributary slot set used to meet transport requirements respectively corresponding to the M services;
- and
- map the M services to the variable optical payload unit according to the mapping procedure.
A multi-service receiving apparatus comprising:
- a processor;
- and
- a memory configured to store instructions that, when executed by the processor, cause the processor to:
- obtain a variable optical payload unit through parsing;
- and
- extract overhead information from an overhead area of the variable optical payload unit, and determine a demapping procedure for the variable optical payload unit based on the overhead information, wherein the demapping procedure is used to obtain M services from the variable optical payload unit through demapping by using a programmable tributary slot group frame, the programmable tributary slot group frame is used to meet transport requirements respectively corresponding to the M services;
- and
- obtain the M services from a payload area of the variable optical payload unit through demapping according to the demapping procedure.
