基于虚级联的链路容量调整方案

Link capacity adjustment schemes based on virtual concatenation

智能化是当前光网络研究的一个热点问题,在同步数字系列(SDH)网络中使用基于虚级联的链路容量调整方案(LCAS)能有效地增强SDH的智能性,减少带宽的浪费,并能增加SDH网络的健壮性。文章讨论了链路容量调整方案的原理及带宽动态调整过程,分析了宿端回送成员状态的产生及传送方式。

Intelligence is one of the key points in the study area of optical networks. LCAS can increase the intelligence of SDH network, reduce the waste of bandwidth and increase the robustness of SDH network. In this paper we discussed the principle of link capacity adjustment schemes and the dynamic bandwidth distribution process, and analyzed the generation and transfer mode of the sink member status.
