摘要
提出一种基于交叉虚级联(Cross Virtual Concatenation)的100Mb/s以太网接入SDH网络的实现方案,设计利用2个VC-12和2个VC-3级联的收发速率适配单元,通过时序仿真,分析了时延对局域网数据传输的影响,验证了使用不同质虚容器级联方案实现数据复用的可行性。
Put forward a new mapping method based on Cross Virtual Concatenation of SDH,It can implemented 100 Mbps Ethernet data access to SDH optic transmission systems with two types of VC＇s namely VC-3 and VC-12 which are used for standard rate access of SDH;Meanwhile,analyzed data delay for the LAN transmission through SDH with way of timing simulation;Verified the feasibility of virtual concatenation using VC＇s of different capacity in one VCG for data multiplexing.
