There is a pressing need for Asynchronous Transfer Mode (ATM) traffic measurements to validate/verify a large number of simulation and analytical studies of ATM networks. In this paper, results from a measurement study of traffic on a wide area ATM network, the very High Speed Backbone Network Service (vBNS) network are reported. We illustrate how the traffic characteristics change as the traff...

This chapter provides history of routing to cognitive routing . Firstly i t reviews hardwired routing a kind of switching to dynamic routing for telecommunication network starting with dynamic alternate routing (DAR) to ATM (Asynchronous Transfer Mode) routing. Secondly it presents routing in data network or packet switching. Thirdly it reviews routing for wireless multi hop network with specia...

In 1999, the ATM Forum international consortium approved the first version of its ATM security specifications, whereas the Internet Engineering Task Force (IETF) published a series of IP security RFC. The aim of those documents is to protect communications over Asynchronous Transfer Mode (ATM) network, respectively the Internet Protocol (IP) network by offering data confidentiality, partners au...

A modern telecommunication service is portrayed as a complex system and is characterized by its stochastical attributes and fuzzy performance considerations. Asynchronous transfer mode (ATM) telecommunication is studied as an example of such a complex system. A call admission control (CAC) procedure is developed using a fuzzy inference method applied to the complex connection patterns of ATM se...

One of the most promising solutions for Broadband ISDN is the Asynchronous Transfer Mode(ATM). Many ATM switch designs have been proposed, which provide a high throughput and a low cell loss probability. The most common design is based on multistage interconnection networks. In this type of design, dedicated buffers may be at either the input ports or the output ports, or at both input and outp...

The OSU scheme is a rate-based congestion avoidance scheme for ATM networks using explicit rate indication. This work was one of the rst attempts to de ne explicit rate switch mechanisms and the Resource Management (RM) cell format in Asynchronous Transfer Mode (ATM) networks. The key features of the scheme include explicit rate feedback, congestion avoidance, fair operation while maintaining h...

Plain ATM (Asynchronous Transfer Mode) has poor performance in case of Data transmission. In order to improve its performance many Buffer Management Mechanisms have been proposed, e.g. push-out. The aim of this paper is to propose improved approach to push-out based on the analysis of various packet discard policies, and create a simulation model in GPSS (General Purpose Simulation System) in o...

Broadband integrated services digital network(B-ISDN) efforts are driven by the emerging needs for high-speed communications and enabling technologies to support new integrated services. Among the available technologies, asynchronous transfer mode (ATM) has emerged as a standard for supporting B-ISDN. ATM uses short, fixed-size cells consisting of 48 bytes of payload and 5 bytes of header in or...

This paper presents the results of an investigation of collective communication operations for distributed computing across asynchronous transfer mode (ATM) networks. Several collective operations have been implemented and studied on a three-switch ATM network testbed at Michigan State University. The methods use virtual topologies constructed from ATM virtual channels. A particular type of vir...

This paper presents a simulation study into the problem of conveying Internet protocol (IP) packets over an asynchronous transfer mode (ATM) network in cases where quality of service (QoS) is an important consideration. The main focus of the work is on mapping IP packet flows onto ATM cell streams, particularly for the purpose of maintaining the QoS requirements of continuous media (audio and v...
