【摘要】 选择了一种使用光缓存器比较少的网络——光弹性分组环进行了全光分组交换实验。该网络的净负荷不进行光/电/光转换,只对帧头进行转换、地址识别和调度,从而克服了光电转换的电子瓶颈。在光节点上,只需使用一个全光缓存器作为转发缓存器,而使用了两个电缓存器分别作为下路接收缓存器和上路发送缓存器。报告了该实验网络的拓扑、节点结构、数据通道、MAC层的数据通道控制子层以及所使用的光缓存技术。更多还原

【Abstract】 An experimental network for all-optical packet switching——Optical Resilient Ring(O-RPR) is reported,in the node of which one optical buffer for transition is utilized,and two electrical buffers for down from ring are used and added to ring.In O-RPR network,when the optical data(payload)passes through an intermediate node,the conversion of O/E/O is not needed in order to overcome the bottleneck of O/E/O.The network topology,structure of optical node,data path,control of data path sublayer in MAC and data buffering technologies are reported.更多还原
