“…[1][2][3][4] This class of access arrangement is targeted at digital video services, such as interactive video, but it can also be used to support work-at-home arrangements, Internet access, home shopping, and telephony applications. HFW systems-still in their infancy-are the high-bandwidth two-way transmission networks that are envisioned to be similar to fixed wireless access for telephony.…”

“…So far, the reference service model for such data services has been loosely fashioned from an initial request for proposals (RFP) by Cable Labs [2]. Over the last couple of years the IEEE Project 802.14 Working Group has been developing a set of specifications for physical and data link layer protocols [3, 41, including ADAPt+ [5], which will be applicable to supporting data service over cable networks and other broadband access infrastructures [6]. More recently, the Internet Engineering Task Force (IETF) has created the IP over Cable Data Networks (IPCDN) Working Group to address data service architectural issues similar, if not identical, to those applying to the initial Cable Lab's proposal.…”

The current state of the art in digital broadband access technologies to support emerging telecommunications services makes imminent the introduction of interactive broadband servicesincluding data, video and the Internetinto the residential market. Over the last few years, much attention has been paid to the development of media access control protocols for cable TV network4 that will allow the immediate support of broadband data services as the first stLp toward enhanced communications services for residential users. Here we review some of the architectural options that must be carefully considered in order to deliver IP ser.vices to such users in an efficient yet flexible manner. residential cable data services are expected to r Internet access, work-at-home applications, business access, local area network LAN-LAN erconnect, and LAN emulation services over cable networks. These services are anticipated as a natural extension to the residential consumer market of the data networking capabilities in the business sector today [ 11.Although related residential Internet Protocol (IP) services are already being trialed in the marketplace, substantive standardization efforts in this area did not materialize until quite recently. So far, the reference service model for such data services has been loosely fashioned from an initial request for proposals (RFP) by Cable Labs [2]. Over the last couple of years the IEEE Project 802.14 Working Group has been developing a set of specifications for physical and data link layer protocols [3, 41, including ADAPt+ [5], which will be applicable to supporting data service over cable networks and other broadband access infrastructures [6]. More recently, the Internet Engineering Task Force (IETF) has created the IP over Cable Data Networks (IPCDN) Working Group to address data service architectural issues similar, if not identical, to those applying to the initial Cable Lab's proposal. In order to ensure interoperability among vendors, a common data service framework that clearly specifies how IP-based services could be implemented over CATV and other similar access networks will be required. This service specification would be expected to identify required hardwarelsoftware components, signaling interfaces between them, and IP transportlrouting services over the access network, as well as network provisioning, configuration, and management. Among the data networking issues, special attention should be paid to: * Configuration of the physical and logical (IP) subnetworks 0 Support for data forwardinglrouting services, including IP Address Resolution Protocol (ARP) and the Internet Control Message Protocol (ICMP) * Host address configuration Subscription * Security In addition, any proposed access architecture for broadband residential data services will be expected to support existing IP services such as the Dynamic Host Configuration Protocol [6], Domain Name System [8], IP Multicasting and Internet Group Management Protocol [9], Resource Reservation Protocol [lo], Integrated Serv...

“…Internet access or Interactive TV). Several proposals have been recently submitted to the IEEE 802.14 WG committee and/or published [l], [4], [5] and [6], with a draft standard having been released in December, 1996. From the point of view of upstream access for data services the first two protocols, [I] and [4], are based on a similar principle.…”

“…While the signalling mini-slots may be subject to collision, the actual data is transmitted, based on the capacity allocated by the Head-End, collision free. On the other hand, the protocols described in [5] and [6] have implementations where the Head-End is responsible for periodically tagging certain slots (within a multi-slot frame) to be reserved and others to be up for contention. As a result, there is no "signalling" and thus the actual data collides within the contention parts of the frame.…”

The paper provides insight into the pe$ormance of a candidate IEEE 802.14 MAC protocol for Hybrid FibreKOax (HFC) networks, by simulation. The simulations make use of two types of input traffic: measured traffic traces, and randomly generated memoryless traffic. It is confirmed that the protocol does not reach congestion collapse under any traffic load, and this is found to hold regardless of traffc type. The paper demonstrates that memoryless traffic streams cannot be used for dimensioning guidelines as they underestimate delay as compared to real traffic traces. The paper also compares between the peij-ormance of the protocol loaded by traffic traces with that of a benchmark based on an ideal multiplexer under the same traffic conditions. It is demonstrated that both the throughput and delay performance of the protocol converge to that of an ideal multiplexer, with an increasing number of active stations.0-7803-3925-8/97 $1 0.00 0 1 997 IEEE
