Our prototype of a fully-functional Asynchronous Transfer Mode (ATM) switch validates the design of a 128 Gb/s optoelectronic ATM switch. Optoelectronics, rather than all optical componets, are used to simutaneously address all of the speci c requirements mandated by the ATM protocol. In this paper, we present the Illinois Pulsar-based Optical Interconnect (iPOINT) testbed, and present our resu...

We consider a problem motivated by the design of ATM (Asynchronous Transfer Mode) networks. Given a physical network and an All-to-All traffic, the problem consists in designing a virtual network with a given diameter, which can be embedded in the physical one with a minimum congestion (the congestion is the maximum load of a physical link). Here we propose a method to solve this problem when t...

Recent analysis of real network traac has shown that a large number of traac sources produces a traf-c stream that is self-similar over several time scales. Motivated by this observation a high-speed Asynchronous Transfer Mode (ATM) traac generator based on fractional Brow-nian motion is presented. The traac simulator generates call arrivals as well as the desired traac parameters for each call...

Due to cost eeciency, future personal communication networks likely will utilize the Asynchronous Transfer Mode (ATM) technology to connect components of the land network infrastructure. In order to cope with bandwidth limitation on the radio access, voice is transmitted as compressed low bit-rate information. The ATM Adaptation Layer 2 (AAL-2) is designed to handle this type of low bit-rate tr...

Abstracrt Asynchronous Transfer Mode (ATM) has emerged as most promising technology in supporting broadband multimedia communications. Congestion control plays important role in the effective and stable operation of ATM networks. In this paper, we described several existing rate based congestion control schemes namely, Explicit Forward Congestion Indication (EFCI), Enhanced Proportional Rate Co...

Ž . The ATM Asynchronous Transfer Mode network is regarded as effective for a multimedia telecommunication environment that enables high-speed and broadband communication. This paper reports on the system architecture and Ž . design concept of the FETEX-150 ESP Enhanced Switching Platform which has been designed as an ATM switch in a public broadband network. To track the latest ATM standards a...

In this paper we display a practical approach adopted for the formal verification of Fairisle ATM (Asynchronous Transfer Mode) switch port controller using model checking. The ATM port controller is part of the Cambridge Fairisle ATM network and plays a key role in the ATM switching process. In particular, we present our experience on the model checking of the ATM port controller using the VIS ...

This paper presents an overview of the existing traffic models for data, voice and video sources in ATM. The first paragraph is devoted to bursty traffic of constant throughput, based on classical ON/OFF model. Obviously the superposition of several independent sources gives the method for modelling the variable rate streams. Possible solutions for voice traffic are offered by Markov-Modulated ...

When carrying Internet Protocol (IP) traffic over an Asynchronous Transfer Mode (ATM) network, the ATM adaptation layer must determine how long to hold a virtual circuit opened to carry an IP datagram. We present a formal statement of the problem and an empirical study of holding time policies taking network pricing into account. We find that IP traffic shows temporal locality of reference and ...
