OBS核心控制器结构设计与硬件化实现

Design and hardware implementation of an OBS core controller

设计了一个基于JIT协议的OBS核心控制器,该控制器将路由选择和信道调度整合在一个模块中处理,并采用信道资源信息共享与先调度再转发的处理机制,简化了控制器的结构,有效提高了OBS核心节点的处理速度,同时也避免了路由选择的盲目性,减少丢包。在FPGA平台上实现了提出的OBS核心控制器结构并进行了实际测试。测试结果表明:接收完BCP包到发出光开关设置信号的最短时间为100ns。

In this paper, an OBS core controller for JIT protocol is designed. The controllerintegrates router and scheduler into one module and which first schedules then forwards the control improves the processing speed of OBS core node, implemented and tested the proposed core controller time from BCP received to set signal emitted can be realizes shared channel information and a method packet, thus simplifies the architecture and and avoids. the undesirable route selection. We in FPGA, the test result shows that the shortest within lOOns.
