This paper considers a multistage interconnection network based on the Indirect Star Graph topology as a candidate for an ATM (Asynchronous Transfer Mode) switch fabric. We consider both buffered and unbuffered versions of the indirect star. The performance of three existing routing algorithms is studied, and it is found that the packet acceptance probability offered by these algorithms is unsa...

Asynchronous Transfer Mode ATM network tech nology is expected to become a central part of the emerging global information infrastructure ATM net works introduce a number of features that distinguish them from earlier technologies and introduce new is sues in network control This paper o ers a framework for precisely de ning and analyzing alternative ap proaches to the distributed control of AT...

The purpose of this paper is to present a method of modeling a superposition of individual Ethernet sources over an Asynchronous Transfer Mode (ATM) network through neural networks. It is proposed the two-state MMPP model (Markov Modulated Poisson Process) to approximate the aggregated ATM traffic because of its simplicity and analytical tractability. The neural network is able to calculate the...

In this paper, a new two-level ow control scheme using VP credit-based control and stop-and-go rate control for best eeort traac in Asynchronous Transfer Mode (ATM) networks is presented. The proposed ow control scheme can eeciently use the leftover bandwidth after the guaranteed traac has been satissed, thus achieving high band-width utilization. Further, cell loss can also be completely avoid...

The LHC accelerator aims at injecting, accelerating and colliding beams with very well controlled beam parameters (e.g. momentum, orbit, tune and chromaticity). This is a non-trivial task since the super conducting main bending magnets will generate field errors with dynamic effects that may result in beam loss. To overcome this problem, real time control of beam parameters via the Power Conver...

In NGN, many transport-related technologies were considered. One technology discussed is ATM (Asynchronous Transfer Mode) based MPLS (Multi-protocol Label Switching) for its provisioning QOS (Quality Of Service) commitment, traffic management aspects and smooth migration to the BcN in Korea. In this paper, we present preventive congestion control mechanism that uses network signaling informatio...

Modern broadband telecommunication networks are based on multiple transport technologies such as Asynchronous Transfer Mode (ATM), Synchronous Digital Hierarchy (SDH) and Wavelength Division Multiplex (WDM). For resilient networks, recovery mechanisms are existent in each technology. The coordination or interworking aspects of the single layer recovery mechanisms is a challenging problem and ma...

Multiprotocol level switching is a promising technology which plays a vital role in new generation network by improvising QOS scalability speed and it also provide some other features like traffic engineering. MPLS came with a framework that is proficient for routing, switching and forwarding. MPLS has a permit to developing an environment of end-to-end circuits by using any transport protocol....

The Point-to-Point Protocol (PPP) over Asynchronous Transfer Mode (ATM) Adaptation Layer 2 defines the encapsulation that allows a PPP session to be transported over an ATM virtual circuit using the ATM Adaptation Layer 2 (AAL2) adaptation layer. This document defines a set of class extensions to PPP over AAL2 that implement equivalent functionality to Multi Class Multi Link PPP over a single A...
