Method for Calculating the Upstream Buffer Size of the CM Based on Contention Request Mode
基于竞争请求的CM上行发送缓冲区大小的计算方法

The contention request mode of upstream bandwidth allocation for HFC(Hybrid Fiber Coax) network access device CM(Cable Modem) was discussed based on the international standard specification for HFC,DOCSIS specification.Firstly,this paper proposed a Markov Chain model for the contention request algorithm of the CM upstream channel.Based on this model,we proposed an M/M/1/K queue model for the data frame sending process of the CM upstream channel,and deduced a theoretical method for estimating the data frame ...
