%X 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 ...
