通过对常见光交叉连接器(OXC)的改进,提出了一种具有有限波长转换能力的内部光交叉连接节点(L-WIXC),既具备冲突消解能力又降低成本。采用算法编程方法,分析比较了L-WIXC和其他两种现有OXC结构,以及基于不同信令协议的L-WIXC的拥塞性能,结果表明L-WIXC具有较低的拥塞概率,并且基于JET协议的L-WIXC比基于JIT协议的L-WIXC具有更低的拥塞概率。通过搭建L-WIXC仿真平台,测试信号光功率、串扰、误码率、眼图等性能参数,分析讨论了单个L-WIXC节点,以及基于L-WIXC节点的线状网络和网状网络的仿真测试结果。结果表明L-WIXC具有良好的联网性能。
Through the improvement of common optical cross-connect (OXC), an internal optical cross-connect node (L-WIXC) with limited wavelength conversion capability is proposed, which not only has the ability of conflict resolution but also reduces the cost. By using the algorithm programming method, the L-WIXC and two other existing OXC structures are analyzed and compared, and the congestion performance of L-WIXC based on different signaling protocols is analyzed. The results show that L-WIXC has lower congestion probability and is based on the JET protocol L-WIXC has lower congestion probability than L-WIXC based on JIT protocol. By building the L-WIXC simulation platform and testing performance parameters such as optical power, crosstalk, bit error rate and eye diagram, the simulation of a single L-WIXC node and linear and mesh networks based on L-WIXC nodes are analyzed and discussed Test Results. The results show that L-WIXC has good networking performance.
