Performance of IEEE 802 local area networks

Abstract: Analytical methods which incorporate actual IEEE 802 media access control (MAC) protocol standard requirements for frame structure, propagation delay, medium data rate, access method, etc., are discussed. Equations were derived and implemented in a computer program to compare the performance of the IEEE 802.3, 802.4, and 802.5 protocols. Delay, throughput, and efficiency are used as a metric for the comparison. >

LAN/MAN interworking in the 802.6/SMDS environment

Abstract: The tremendous growth of local area networks (LANs) is creating a demand to interconnect them over distance. Metropolitan area networks (MANs) provide an optimal platform for interconnecting LANs, since they combine high performance with LAN-like sharing of bandwidth over a large geographic area. A description is given of the primary issues, needs, and architectural approaches to LAN/MAN interconnection. Regarding LANs, the focus is on IEEE 802 LAN architectures, since they are by far the most common and have become part of the open systems interconnection (OSI) standard suite. Regarding MANs, the focus is on the IEEE 802.6/SMDS (switched multimegabit data service) MAN architecture. >

Fiber optics backbone for IEEE 802.3 networks

Abstract: In the last few years the IEEE 802.3 committee has developed fiber optics inter-repeater link standard called FOIRL. This standard defines the "Fiber Optics Media Access Unit" (FOMAU) which is used to connect two IEEE 802.3 repeaters that are up to 1Km apart. The IEEE 802.3 lOBaseF task force is currently standardizing a full F/O system in two directions: passive and active. The active approach is a compromise between the FOIRL (Asynchronous) approach and the Synchronous approach. As a result of this activity the IEEE 802.3 standard will define three different F/O interfaces and several devices that will not inter-operate. Such a standard will lower the credibility among the IEEE 802.3 user community, as customers will be confused amidst the many chapters and devices with no clear choice. This paper describes a method that can reduce the number of standards to two (passive and active), while proposing a solution for all the requirements of 802.3 F/O LAN. (The question of passive vs active approach will be discussed in this paper).
