Abstract: An apparatus and a method for managing traffic by using a VID(VLAN(Virtual LAN) Identification) in an EPON(Ethernet Passive Optical Network) are provided to allow a general commercialized switch or router to smoothly perform traffic management for numerous subscribers and subscriber services. A MAC lookup table(15) matches VIDs to be used within an EPON by MAC address and managing them. A service classification policy table(20) stores service classification references corresponding to service control parameters of each VID. A service control policy table(25) stores service policies to be provided according to each classified service. When a downlink packet is inputted, a MAC look-up module(30) looks up a VID corresponding to a MAC address of the corresponding downlink packet by referring to the MAC look-up table(15). The first service classifying module(35) classifies a VID service class of the downlink packet. The first service control module(40) provides a service of a downlink transmission flow according to the classified VID service class. A VID study module(50) studies VIDs through a packet frame of an uplink packet and updates the MAC look-up table(15). The second service classifying module(55) classifies a VID service class of the uplink packet. The second service control module(60) requests a service according to the classified VID service class in case of an uplink transmission flow.

Abstract: PURPOSE: A time domain equalizer of a VDSL transmission system is provided which effectively reduces the amount of hardware and guarantees compatibility with asymmetric digital subscriber line transmission systems. CONSTITUTION: A time domain equalizer of a VDSL transmission system is constructed in a manner that time domain equalizers by signal bands are serially connected for signal bands obtained by dividing the entire signal band. A time domain equalizer(42) for a high frequency signal band and a time domain equalizer(41) for a low frequency signal band are serially connected. The time domain equalizer for a high frequency signal band and the time domain equalizer for a low frequency signal band obtain the signal bands using an algorithm for reducing a channel impulse response length. The time domain equalizer for a low frequency signal band connects a shift register between tabs to decrease data loss.
