MLAP: a MAC level access protocol for the HFC 802.14 network
TLDR
This work introduces a very versatile MAC protocol for the HFC 802.14 network, MLAP, which can provide integrated broadband services to the home, internetwork easily with ATM wide area networks, support QoS constraints for various types of traffic, and operate over a variety of physical layer protocols.Abstract:
Interactive residential broadband/multimedia services are expected to be the next main event in the cyberspace experience. The large excess bandwidth (well over 300 MHz) available in today's cable TV (CATV) hybrid fiber/coaxial (HFC) plants is an ideal candidate to provide the underlying communications infrastructure for interactive digital services to the home; cable operators that have not yet upgraded their all-coaxial plants to HFC are quickly moving in this direction. MLAP is a flexible ATM-friendly MAC protocol that is capable of supporting various types of traffic with diverse quality-of-service requirements. We introduce a very versatile MAC protocol for the HFC 802.14 network. MLAP can provide integrated broadband services to the home, internetwork easily with ATM wide area networks, support QoS constraints for various types of traffic, and operate over a variety of physical layer protocols. Our presentation is only an extended summary of our medium-sharing protocol proposal to the IEEE 802.14 WG. We consider only error-free system operation. MLAP provides for the use of timers for the recovery of error situations in the network. MLAP is also supported by a management suite of protocols for management of the overall system.read more

A review of contention resolution algorithms for IEEE 802.14 networks
TL;DR: Different implementations for several well known contention resolution algorithms such as tree-based and p-persistence are presented and their performance is evaluated in the HFC context with respect to upstream channel allocation, roundtrip delay, various traffic types, and number of stations in the network.

Q -ary collision resolution algorithms in random-access systems with free or blocked channel access
P. Mathys,Philippe Flajolet +1 more
TL;DR: The throughput characteristics of contention-based random-access systems (RAS's) which use Q -ary tree algorithms of the Capetanakis-Tsybakov-Mikhailov-Vvedenskaya type are analyzed and it is concluded that the "practical optimum" RAS uses free channel access and ternary splitting with binary feedback.

TL;DR: The resurgence of interest in the combination of fiber and coaxial cable has led it to the acronym HFC, for hybrid fiber-coaxial, since it is no longer just the province of cable TV.
