The aim of this paper is to present data performance analyses in Asynchronous Transfer Mode (ATM) network. Cells generated by different type of traffic sources face different priority schema entering the ATM switch. That is because of the different nature of the service used. Real-time services like telephone and video obtain higher priority. Elastic traffic, or data services are considered to ...

Congestion control in the Available Bit Rate (ABR) class of Asynchronous Transfer Mode (ATM) networks poses interesting challenges due to the presence of delays, magnitude and rate constraints on the inputs and additive disturbances. In this paper, we consider a discrete-time fixed-structure controller for an ATM/ABR switch, also modeled in discrete-time, and solve a robust tracking control pro...

Asynchronous Transfer Mode is becoming a widespread technology for both local and wide area networks. We describe our ATM-connected computing and storage resources at Adelaide and Canberra. We report on measurements of the performance of our system and discuss the implications for wide area distributed, high-performance computing (DHPC) applications. In particular we discuss eeects of bandwidth...

The asynchronous transfer mode (ATM) Forum has chosen rate-based control as the flow control scheme for available bit-rate (ABR) service. However, rate-based schemes can achieve congestion control only if all users act in a cooperative manner. Even a limited number of uncooperative users can cause congestion collapse. In this paper, we propose a mechanism called fair packet discarding to provid...

Congestion control in the Available Bit Rate (ABR) class of Asynchronous Transfer Mode (ATM) networks poses interesting challenges due to the presence of multiple-delays, magnitude and rate constraints on the inputs, amplitude limitation on the state, and additive disturbances. In this paper, we consider a fixed-structure controller for an ATM/ABR network, and solve a robust tracking control pr...

Introducing the Asynchronous Transfer Mode (ATM) causes a backwards compatibility problem, because ATM is connection-oriented whereas most of today’s LANs are connectionless. Interconnection can be achieved by the use of connectionless servers (CLS). These servers together with a number of preestablished virtual circuits form a connectionless overlay network on top of ATM. In this paper we eval...

This document analyses the security of the BGP/MPLS IP virtual private network (VPN) architecture that is described in RFC 4364, for the benefit of service providers and VPN users. The analysis shows that BGP/MPLS IP VPN networks can be as secure as traditional layer-2 VPN services using Asynchronous Transfer Mode (ATM) or Frame Relay. Behringer Informational [Page 1] RFC 4381 Security of BGP/M...

This paper describes modeling of the Available Bit Rate (ABR) source traffic in Asynchronous Transfer Mode (ATM) network using Pos EXP BL GT / traffic generator, which employs Poisson distribution for modeling the burst length ( Pos BL ) and Exponential distribution for modeling the gap time ( Exp GT ). This traffic generator inherits the advantages of both Poisson and Exponential distribution ...

Abstract: This paper evaluates a Virtual Connection Tree (VCT) algorithm for mobile Asynchronous Transfer Mode (ATM) handoff that offers service adaptability and efficient allocation of wired resources is applied to different multiple access techniques. This creates a more distributed system where decisions about traffic conditions in different areas can be evaluated at the Base Station (BS) le...

Asynchronous Transfer Mode (ATM) has emerged as a backbone for high-speed broadband communications networks. In this paper we present ATM switch design starting from a parametric high-level model, validating the model using a combination of formal veriication and simulation. We used a combination of theorem proving and model checking to discover bugs in the high-level model that was presumed co...
