First, the stations'timing process and the slot aligning are discussed. Second, the dissertation propose a resource request random access method based on feedback. The performances of this method are analyzed. Third, proceed from the considerations of the MAC protocol for the HFC system, a QOS-oriental scheduling algorithm for the MAC protocol based on dynamic TDMA is proposed. Simulation results show that the performance of this algorithm is better than that of the first come first service. Forth, two contention resolution algorithms ----p-persistent CRA and tree CRA, which are usually adopted in the HFC system, are summarized. The delay and characteristic are compared. At last, the dissertation introduces the function implementation of the MAC layer based on COM21 UPSTREAMS.
