FIELD: optical communications. ^ SUBSTANCE: in accordance to the method, traffic is classified which is supposed to be transmitted between optical communication line terminal (OLT) and modules of optical communication network, to multiple types of services, and different priorities are assigned to each type of services; service ports are sanctioned for each type of services for transmitting service data in decreasing sequence of service priorities, and information about permission of service ports, received from sanctioning stage, is recorded; information of permission of each provided service port is read for the same module of optical communication network (ONU); and provided initial data transmission moment is planned for each provided port of current module of optical communication network (ONU), messages are formed about permission of downlink, which contain information about permission and provided initial data transmission time moment for each provided port of current module of optical communication network (ONU), messages about permission of downlink are transmitted to current module of optical communication network (ONU). ^ EFFECT: increased coefficient of usage of pass band and realization of even distribution of the aforementioned pass band. ^ 16 cl, 9 dwg |
