The Folded Hypercube ATM Switches
… high performance asynchronous transfer mode (ATM) switches have been proposed. The majority of these switches have high performance but also high hardware complexity. Therefore, there is a need for switch designs with low complexity and high performance. This research proposes three new ATM …

Replicative Senescence is ATM-Driven, Reversible, and Delayed by Reduced ATM Activity at Low Oxygen
… the nature of the activated DDR is unclear. ATM kinase activation at critically short telomeres has been implicated in the induction of senescence, suggesting that the shortest telomeres lack su]icient TRF2 to repress ATM signaling. However, ATM-deficient cells also undergo replicative …

MMPP modeling of ATM multimedia traffic
… and study its performance for representing the ATM traffic. Starting with a superposition of voice sources, the performance of various techniques to model the superposed stream by a 2-state MMPP is compared. Then the techniques are generalized for an arbitrary aggregated ATM traffic, …

Dynamic bandwidth allocation in ATM networks
… transport new emerging bursty traffic types in ATM networks. However, existing ATM traffic management solutions are not readily able to handle the inevitable problem of congestion as result of the bursty traffic from the new emerging services. This research basically addresses bandwidth …

Connection admission control in ATM networks
… connection admission control for use in future ATM networks is presented. Traffic management and control strategies proposed in the literature are suveyed. An architecture for managing and controlling traffic in ATM networks is then presented. Based on this framework a connection admission model …

Multicast Video Transport overiPOINT ATM Testbed
… we have designed and implemented a novel ATM Network Video Interface Module. This module receives ATM cells from an ATM switch port, performs all the re-assembly functions and extracts video data from the adaptation layer frames. This module also detects any lost data in the video stream …

Error Control in Wireless ATM Network
Asynchronous Transfer Mode (ATM) protocol was designed to support real-time traffic steams over high quality links like fiber optics where the transmission error is extremely low. ATM performs poorly in an error-prone environment such as wireless communications. The purpose of this research is to …

On the formal verification of ATM switches
… expressing a property are illustrated. Although ATM hardware is hard to design due to its high speed and various features. the applications of model checking and equivalence checking on ATM hardware verification are few. In this thesis, Fairisle ATM switch fabric, Fairisle ATM null port …

Supporting real time video over ATM networks
… and tag such independent video slice at the ATM layer for early discard. This involves the use of a tag cell differentiated from the rest of the data by its PTI value and a modified tag switch to facilitate the selective discarding of affected cells within each video slice as opposed to …

ATM over an asymmetric digital subscriber line
… and considers Asynchronous Transfer Mode (ATM) transport in the ADSL network. To analyse the ADSL access network, a simulation was developed using C++ and MATLAB. The thesis outlines the background and implementation of ADSL in the opening sections and then moves on to details about …

Novel techniques in large scaleable ATM switches
… explores the research area of large scale ATM switches. The requirements for an ATM switch are determined by overviewing the ATM network architecture. These requirements lead to the discussion of an abstract ATM switch which illustrates the components of an ATM switch that automatically …

Visualisation of ATM network connectivity and topology
ATM and dynamic reconfiguration allow for rapid changes in a virtual path network depending on traffic load and future demands. This technology improves the utilisation, lowers the call blocking probability and increases the overall performance of a network. However, it poses several management …

Statistical Analysis of ATM Call Detail Records
… resources, such as Asynchronous Transfer Mode (ATM) networks and emerging Internet Protocol (IP) networks employing Differentiated Services (DiffServ). This work shows a method to generically classify traffic in an ATM network such that capacity planning may be possible. These methods are …
