A new multiple-valued current-mode (MVCM) integrated circuit based on dual-rail differential logic, whose currentdriving capability is high at a low supply voltage, is proposed to realize a totally self-checking circuit and an asynchronous-control circuit. Two nMOS transistors with different threshold voltages are used as complementary pass switches in the proposed differential-pair circuit (DP...

CellCase is a commercial high-speed encryptor for Asynchronous Transfer Mode (ATM) networks, available since 1997. It provides data confidentiality and entity authentication at the ATM layer, encrypting ATM cell payloads at rates from T1 (1.5 Mb/s) to OC-12c (622 Mb/s). Though deployed prior to the adoption of the ATM Forum Security Specification (1999), CellCase implements many of the mechanis...

Multicast is a very important building block in modern high-speed networking. This document 1 is an overview of both existing multicasting techniques as well as proposed extensions and optimizations to today's IP Multicast. We also discuss multicasting techniques for Asynchronous Transfer Mode (ATM) Networks, especially the problems and issues that arise in conjunction with IP multicast and the...

The asynchronous transfer mode (ATM) adaptation layer type 1 (AAL1) segmentation and reassembly (SAR) are designed and implemented by the field programmable gate array (FPGA). The SAR header is generated and processed in the FPGA and the SAR payload is stored in an external first-in–firstout (FIFO) device. A method to recover the source clock, called synchronous residual time stamp (SRTS), is i...

The video performance of the Median wireless asynchronous transfer mode (WATM) system is evaluated for a range of application scenarios using the H.263 video codec and a novel packetisation and acknowledgement scheme. The video resolutions and system parameters used are summarised in Tables 1 and 2. The required channel signal-to-noise ratio for near-unimpaired video quality is about 16dB over ...

Flow control allows sources to adjust their bandwidth usage to the level of availability in a network, and hence reduces packet loss, increases network utilization, and prevents/reacts to network congestion. The Internet uses TCP flow control; Asynchronous Transfer Mode networks will use rate based flow control. In this paper we present an optimization approach to rate based flow control. We de...

The world of wireless telecommunications is rapidly changing. The capabilities of wireless networks are improving at a steady pace. This paper presents a protocol implementation for implementing mobility in an Asynchronous Transfer Mode (ATM) network. The vision of the authors is of one \ATM-based wireless telecommunications network" that is capable of supporting a variety of today's applicatio...

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, highperformance computing (DHPC) applications. In particular we discuss e ects of bandwidth ...

Multimedia is an emerging service which integrates voice, video and data in the same service. With the progress made in high speed large capacity multimedia servers, high speed networks, QoS, service guarantees and set top boxes, it is currently possible to cost effectively and efficiently carry multimedia over high speed networks. This paper surveys the progress made, and the future of efficie...
