Typical Performance

Technological advances such as high speed Ethernet and ATM have provided a means for business organizations to employ high performance networking. However, few studies have been conducted to verify the architecture's typical performance in a business environment. This study analyzed the network performance of high speed Ethernet and ATM when they were configured as LAN backbones. The results revealed that ATM exhibited performance superior to high speed Ethernet, but when adjustments were made for differences in line speed, the throughput was similar. In addition to analyzing empirical data about each technologies' performance, the advantages and limitations of using ATM in a business network are discussed.

Basic Concepts

With the emergence of high-speed optical transmission, the pre-existing plesiochronous digital hierarchy (PDH) appeared unsuitable for achieving network synchronization, leading to the development of the synchronous optical network (SONET) and synchronous digital hierarchy (SDH) as the two equivalent standards for circuit-switched optical networks. Several bandwidth-efficient techniques were also developed to carry packet-switched data traffic over SONET/SDH networks, offering some useful data-over-SONET/SDH architectures. Subsequently, with the increasing transmission rates for SONET/SDH and Ethernet-based LANs, a convergent networking platform called optical transport network (OTN), was developed. With the ever-increasing volume of bursty data traffic, a standard for packet-switched ring networks, called resilient packet ring (RPR), was also developed for better bandwidth realization in optical fibers. In this chapter, we first present the SONET/SDH networks and the techniques for supporting the data traffic therein, followed by a description of the basic concepts and salient features of the OTN and RPR networks.

Scanning Electron

California State University, Hayward has successfully demonstrated remote control of a scanning electron microscope (SEM) using Asynchronous Transfer Mode (ATM). The development of digital imaging technology has iead to exploration and testing of networking strategies for sharing scientific instrumentation. The concept of shared instrumentation is appealing to both academia and private enterprise. Networking access presents the opportunity to teach scanning electron microscopy to a large number of students using multiple desktop computers. Video images can also be projected onto large screens in classrooms or as a distant learning resource. Remote shared access to scientific equipment provides certain advantages such as access to a wider variety of resources, direct interaction without hazard to people or equipment, ability to combine resources into larger virtual instruments, rapid access to available resources, and pooling of knowledge by a larger community.The advent of high speed networks such as ATM offers the possibility of integrated solutions to communication and control.

A tendência atual de integração de serviços de dados, voz e vídeo, estimulada pelo pleno sucesso da Internet, aumentou a demanda por maior banda e melhor desempenho nas redes de comunicação de dados. Neste contexto, a tecnologia ATM (Asynchronous Transfer Mode) vem sendo utilizada na implementação de backbone de LANs e WANs, justamente por oferecer a possibilidade de integração de serviços com qualidade, alta escalabilidade e altas taxas de transferência em banda larga. Neste artigo serão abordados os principais conceitos relacionados à tecnologia ATM, suas vantagens e desvantagens em face de outras tecnologias (como Fast e Gigabit Ethernet), além de casos de sua utilização em empresas e instituições de ensino.

This research paper compares two popular backbone network technologies – Gigabit Ethernet and Asynchronous Transfer Mode (ATM). ATM has been a popular choice for years for providing multimedia applications over the network effectively by making use of its features like Quality of Service (QoS). Gigabit Ethernet matches ATM’s functionality by providing higher bandwidth at lower cost, less complexity and easier integration into the existing Ethernet technologies. Hence, it becomes important to compare these two technologies against various network performance metrics to find out which technology performs better for what type of applications under what circumstances. This research paper will analyze and compare the performance of those two technologies based on the throughput, end-to-end delay for Voice and Video conferencing and jitter for the Voice applications. For this purpose, two different simulations were created, one for the Gigabit Ethernet and the other one for the ATM network, using the popular commercial and academic simulation software – OPNET modeler.
