Proliferating deployment of amphidromic broadband services over commercial cable TV networks is bringing a taste of IBCN capabilities to vast numbers of domestic customers. The fluctuating and unpredictable traffic of the new services favours TDMA multiplexing of traffic from many customers inside each channel for flexible and dynamic bandwidth sharing on the basis of a medium access protocol. As penetration grows, traffic aggregations will exceed the capabilities of store-and-forward switching bringing more and more into prominence fast switching techniques and ATM networking. The first HFC systems designed primarily for LAN interconnection and Internet traffic are not optimised for ATM sources even when they employ ATM cells as a unit of transport. A novel contention approach designed to greatly reduce the distortions to traffic profiles characterising first generation HFC medium access protocols is the theme of this paper. The proposed method provides a high number of simultaneous orthogonal contention opportunities which allow quick identification of cell arrivals which is a key to preserving temporal relationships of contending traffic, vastly reducing cell delay variations in line with the traffic control philosophy of ATM.
