Description

technical field

[0001] The invention relates to a network communication system, in particular to a resource scheduling method and system for a photoelectric hybrid system. Background technique

[0002] A basic trend of next-generation network development is an IP-based full-service network. For cable (cable) operators, such as radio and television, in order to make full use of their existing large number of CABLE home access lines, a hybrid of passive optical network (Passive Optical Network, PON) and coaxial broadband network (Ethemet over Cable, EOC) is proposed The network transformation plan of the network, the mixed network of PON and EOC is usually expressed as "PON+EOC". Such as figure 1 The schematic diagram of a typical PON+EOC network is shown. The network includes PON, EOC and background management system. Among them, PON includes OLT (Optical Line Terminal, Optical Line Terminal), ODN (Optical Distributed Network Optical Distribution Network ) and the optical ...
