摘　　要：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。A novel optical cross connection named limited wavelength conversion wavelength interchangeable cross connection（L-WIXC） is proposed to improve the conflict resolution and decrease the cost.The optical architecture and network control system of L-WIXC as well as corresponding control algorithm are described.By means of comparing congestion properties of several different OXC structures and different signaling protocols,it can be concluded that the congestion of L-WIXC is lower,and L-WIXC with JET protocol has better congestion probability than that with JIT protocol.A simulation platform is also built for testing the performance of L-WIXC.The tests are done and analyzed for single L-WIXC node,serial links with L-WIXC and mesh links with L-WIXC by simulating the optical power,crosstalk,BER and eye diagram.The results show that L-WIXC has satisfying performance for applying in optical switching networks,especially in optical burst switching network.
