SDH虚级联信号的链路容量调整机制LCAS及其标准的新发展

Link Capacity Ajustment Scheme (LCAS) for SDH Virtual Concatenated Signals and the Development of Its Specification

通用成帧规程GFP、VC虚级联和链路容量调整机制LCAS是有效实现Data over SDH(DoS)的新型协议。本文分析了LCAS的特点和结构,及相关标准的最新一些进展。

Built on the powerful combination of GFP, virtual concatenation and the link-capacity adjustmentscheme (LCAS), network operators can allow adjust pipe capacity. This paper mainly described the characteristics and structure of LCAS. The recent development of the related technical specification of LCAS also introduced.
