APPARATUS AND METHOD FOR SUPPORTING/CONTROLLING FUNCTIONS ASSOCIATED WITH QOS IN EPON SYSTEM

摘要

An apparatus and a method for supporting/controlling functions associated with QoS(Quality of Service) in an EPON(Ethernet Passive Optical Network) system are provided to combine and use a classified class, an output port, and an LLID for the output port using information included into a service packet sufficiently, thereby dealing with various types of QoS by service. A packet classifying unit(200) classifies the class of a packet on the basis of the header information of a service packet. A reading unit(210) searches a port, to which the packet is outputted, and an LLID(Logical Link Identifier) corresponding to the port. A queue operating unit(220) sets a queue waiting in the port and determines the priority of the queue on the basis of the classified class and the output port, and the LLID. A bandwidth control unit(230) allocates a service bandwidth on the basis of at least one of the classified class, the output port, the LLID, or the output queue.
