一种新型全光因特网方案设计及性能仿真

摘要

在详细阐述全光因特网的系统结构和逻辑结构的基础上，以河南省为平台提出了一种新型的具有MESH网络和自愈环网双重网络特性的全光因特网拓扑结构。系统误码性能和光谱特性仿真结果表明，这种类似“蜘蛛网”状的全光因特网拓扑结构具有生存性高、误码率低以及易于故障定位等优点。%On the basis of the describing of the basic system structure and the logical structure of all optical network and taking Henan Province as a platform, this paper presents a new topology of optical Internet which has characteristics of both MESH and self-healing ring network. And furthermore, the BER performance of the system and spectral characteristics of the simulation results show that the all optical Internet topology structure which is similar to that of “spider web”has the advantages of high survival, low bit error rate and easy fault location.
