摘　　要：对链路容量调整机制(LCAS)实现EOS进行了分析,对低阶虚级联LCAS的复帧结构及实现LCAS过程进行了论述,对虚级联组(VCG)实现多通道虚级联初始化过程、LCAS虚级联稳定工作时状态迁移、链路容量带宽增减的动态调整过程及链路临时删除或恢复进行了研究,给出了LCAS虚级联初始化过程和稳态工作过程流程图.对多通道实现虚级联过程中的时延差进行了剖析.对LCAS的实现、估算多通道的时延差和设计接收缓冲储器容量提供了方法和依据.Analyses the Link Capacity Adjustment Scheme（LCAS） which can be used to EOS. The multiframe structure of low order virtual concatenation LCAS and the process of LCAS realization were discussed. The initial process that muti-path virtual concatenation system is realized by VCG, the state transition of LCAS virtual concatenation in steady state condition and the dynamic adjust process of bandwidth by adding or reduction of the number of paths and temporary deletion or recovery of link were further studied. The flow process flow chart of the initial and steady state work process of LCAS virtual concatenation were provided. The time differential delay of muti-path virtual concatenation was investigated. The methods and evidences were provided for the realization of LCAS, the estimation of the time differential delay of muti-path virtual concatenation and the design of receiving elastic store capacity.
