Description

technical field [0001] The present invention relates to the technical field of service perception, in particular to a method and device for service flow perception of an optical access network. Background technique [0002] The optical access network refers to the use of optical fiber as the main transmission medium to realize the information transmission function of the access network. Passive Optical Network (PON, Passive Optical Network) is the main form of optical access network. The main components of the PON system are the optical line terminal OLT (optical line terminal) and the remote optical network unit ONU (Optical Network Unit), which are connected to the service node through the OLT and connected to the user through the optical network unit (ONU). [0003] With the increasing complexity of optical access network services, in order to obtain better QoS (Quality of Service) guarantees, service identification and classification are the premise and basis for implem...
