摘要: To provide residential users with multimedia interactive services, ahigh bandwidth access network solution is required. In this work, we focus on using existing CATV networks to provide high bandwidth interactive services. We first introduce the HFC(Hybrid FiberCoax) architecture of CATV network adnd idscuss the problems in providingtwo way communication over HFC. Second, we discuss the important issues in upstream channel protcol design: 1) overlapping the collision resolution anddata transmission to archive best usage of bandwidth, in which we examine how to arrange the request mini-slots and data transmission; 2) resolving collision, in which we discuss several traditional collision algorithms; 3)resolving the synchronization problem, in which we propose our solution to getthe RTC(Round Trip Correction) parameter. Third, we introduce several proposed IEEE 802.14 protocols for upstream channel and compar these protocols.
