    • The present invention provides a flow based connection admission control method for efficiently using a limited bandwidth to provide an uninterruptible connection over the internet. The present invention comprises: a flow information storage part including flow information and band management information; and a controller allocating a flow identification number for discriminating packets to received packets using header information of the received packets, determining whether the packets are connected by using a flow information table and the flow identification number and allocating or releasing the connection. The packets have a speedy real time property because a connection admission is determined when the packets are transmitted, and, also, can be transmitted without loss with respect to a flow whose connection admission is approved. Additionally, the present invention can secure economic feasibility for a network operator in the case of being applied to a premium service where no packet loss is secured.

    • PURPOSE: An OLT(Optical Line Terminal) in a GPON(Gigabit Passive Optical Network) and a method for transmitting a broadcast frame using the same are provided to retransmit a broadcast frame downstream without having to manage an Ethernet address and an IP address. CONSTITUTION: A PON(Passive Optical Network) connects an OLT(Optical Line Terminal)(10) installed in a telephone office to ONUs(Optical Network Units)(20), also called ONTs(Optical Network Terminals), installed in a home through a passive optical splitter in a point to multi-point scheme. A downstream transmission from the OLT to the optical network unit is performed through a broadcast transmission scheme allowing all packets to be transmitted to the optical network unit. However, an upstream transmission from the optical network units to the optical line terminal is performed by sharing a single optical link with a plurality of optical network units based on various medium access control schemes. A broadcast frame, such as an ARB packet, needs to be output through ports except for a port of an Ethernet switch which has transmitted the broadcast frame. When transmitting a broadcast frame in the GPON(Gigabit Passive Optical Network), two transmission paths are considered based on the direction of a transmission.
    • 目的:提供GPON(千兆无源光网络)中的OLT(光线路终端)和用于发送使用该OLT的广播帧的方法,以便不必管理以太网地址和IP地址来重新下发广播帧。 PON(Passive Optical Network,无源光网络)将安装在电话局的OLT(Optical Line Terminal,光线路终端)(10)连接到ONU(Optical Network Unit)(20),也称为ONT(Optical Network Terminals) 一种无源光分路器,以点对多点方案。 从OLT到光网络单元的下行传输通过允许将所有分组传输到光网络单元的广播传输方案来执行。 然而,通过基于各种介质访问控制方案与多个光网络单元共享单个光链路来执行从光网络单元到光线路终端的上行传输。 需要通过除了发送广播帧的以太网交换机的端口之外的端口输出诸如ARB分组的广播帧。 当在GPON(千兆位被动光网络)中发送广播帧时,基于传输的方向考虑两个传输路径。

    • A hybrid optical transceiver module and a passive optical network comprising the same are provided to package an LD portion in a TOSA structure and package an SOA, a PD, and a WDM coupler in a PLC structure to make two packages into one, thereby solving an optical alignment problem caused by a narrow optical emission angle. A hybrid optical transceiver module is comprised of a first package(100) of a TOSA(Transmitter Optical Sub-Assembly) structure and a second package(200) of a PLC(Planar Lightwave Circuit) platform structure. The first package includes an LD(Laser Diode)(110), a first MPD(Monitor Photo Diode)(130), and a lens(120) for concentrating a transmission optical signal outputted from the LD to emit the transmission optical signal to the outside of the first package. The second package includes an SOA(Semiconductor Optical Amplifier)(210), a second MPD(240), a PD(Photo Diode)(220), an optical waveguide(232), and a WDM(Wavelength Division Multiplex) coupler(230). The SOA receives the transmission optical signal emitted from the first package to emit a high-power transmission optical signal to the outside. The second MPD monitors the high-power transmission optical signal. The PD receives a reception optical signal inputted through an optical fiber(250). The optical waveguide transmits the high-power transmission optical signal emitted from the SOA to the optical fiber. The WDM coupler transmits the reception optical signal to the PD and divides the high-power transmission optical signal and the reception optical signal. The first package and the second package are coupled with each other through optical alignment. A PON(Passive Optical Network) system includes a splitter for transceiving signals to an ONT(Optical Network Terminal) separatedly. The signal is in a TDMA(Time Division Multiplexing Access) type.
