【摘要】 介绍了光弹性分组环(ORPR)节点模型,分析了ORPR网络中流量成型时光分组组装算法,提出一种适合ORPR网络的基于控制发送时间的光分组组装算法,给出了该算法的算法结构,并和传统的光分组组装算法做了比较。该算法通过分组发送间隔的调整,使得分组单位时间内的流量的自相似性被平滑,具有很好地抑制突发性的效果,同时,分组组装的时间门限可以被ORPR调度算法动态调整,可以适应缺乏缓存的ORPR网络的调度机制。更多还原

【Abstract】 The ORPR node model is introduced.Optical packets assembly algorithm is analyzed when traffic shaped in an ORPR network and proposed a new algorithm fit for ORPR network by controlling the time in transmission.The algorithm is based on a hybrid threshold assembly algorithm.It adds a parameter to control the interval between optical packets transmitted so that the traffic in each time unit is smoothed to be less burst.And threshold is adjusted by ORPR scale algorithm,fit for the ORPR network with limited optical buffer.更多还原
