    • PURPOSE: An Ethernet-based next generation optical transport network apparatus and a traffic grooming method of an apparatus thereof are provided to effectively a network resource by supplying the tragic grooming function with each flow. CONSTITUTION: An optical signal which is multiplexed wavelength division in which one or more optical demultiplexers is inputted from optical signal distributors(511, 512) is demultiplexed to each wavelength. A traffic grooming module(530) assigns a new optical virtual channel after separating optical virtual channels from the optical wavelength inputted from the light demultiplexer. An optical wavelength conversion module(560) assigns the new optical wavelength to the signal inputted from the traffic grooming module. One or more optical multiplexers(551, 552) multiplexes a plurality of optical wavelength signals inputted from the traffic grooming module to the wavelength division.

    • PURPOSE: A network generator using wavelength division multiplexing in a local area network and a channel connection method thereof are provided to reduce the possibility of collision by providing a plurality of channels to hosts of the network, and guarantee equity between hosts by preventing connection delay of the network and channel capture. CONSTITUTION: A host selects wavelength for frame transmission before transmitting frames and tunes lasers of a transmitter with the selected wavelength(ST21). A tunable transmitting part senses a carrier on the selected channel and starts frame transmission if the channel is idle(ST22¯ST23). In the case of transmitting a plurality of frames, the host transmits the first frame, and transmits the next frame after standing by during delay time between frames(ST25). If collisions are generated in frame transmission since other host tries transmission with the same wavelength, each host stops frame transmission promptly and transmits jamming signals(ST24, ST26). If the frequency of the collisions is lower than the designated maximum, the host tries transmission on the current channel after standing by during delay time obtained by a BEB algorithm(ST27¯ST28). If the frequency of the collisions is more than the designated maximum, the host jumps to the other arbitrary channel for trying transmission(ST29).
    • 目的:提供一种在局域网中使用波分复用的网络发生器及其通道连接方法,以通过向网络主机提供多个信道来减少冲突的可能性,并通过防止主机之间的连接延迟 网络和频道捕获。 构成:主机在发送帧之前选择帧传输的波长并调谐具有所选波长的发射机的激光器(ST21)。 如果信道空闲,则可调发送部分感测所选信道上的载波,并开始帧传输(ST22〜ST23)。 在发送多个帧的情况下,主机发送第一帧,并在帧之间的延迟时间期间发送下一帧(ST25)。 如果在帧传输中产生冲突,因为其他主机尝试相同波长的传输,则每个主机会立即停止帧传输并发送干扰信号(ST24,ST26)。 如果碰撞的频率低于指定的最大值,主机将在BEB算法获得的延迟时间(ST27〜ST28)之后暂停在当前信道上进行传输。 如果冲突的频率大于指定的最大值,则主机跳转到另一个任意通道进行传输(ST29)。
