The subject of B-ISDN came into being in the late 1980s, together with the concept of Asynchronous Transfer Mode (ATM). ATM is closely tied to high-speed packet switching by means of specialized switches implemented in hardware. Due to its high speed and packet structure, ATM technology was considered attractive to unify voice, data, and video services. A unification of these services over the ...

The advent of the Integrated Services Digital Network (ISDN) has resulted in a resurgence of research activity in the field of image coding. The target is to transmit real time image sequences over a number (< 30) of parallel 64kbit/s channels in order to implement fast document transfer, video telephone facilities and eventually video teleconferencing. Digital images typically occupy a large a...

The easy and cost effective interworking of Distributed Queue Dual Bus (DQDB) and Asynchronous Transfer Mode (ATM) protocols is of prime importance for the evolution of the broadband integrated services digital network (B-ISDN) and the long-term success of MANs as tributary networks. In this paper, we study several practically useful scenarios for the interworking of ATM Customer Premises Netwo...

This paper considers applications of automatic speech recognition and speaker veri cation techniques in developing e cient Voice Messaging Systems for Integrated Services Digital Network (ISDN) based communication systems. The prototype demonstrator presented was developed in the framework of cooperative project which involves two research institutes: the Signal Processing Laboratory (LTS) of t...

We study real time tra c management in the perspective of a four-level model of tra c variations: cells, bursts, sessions, and links. Our interest is focused on the two latter levels: Using virtual channels (VCs) and virtual paths (VPs) as the managed entities on the two levels respectively, we put forward a simple and robust strategy for tra c management in real time: All nodes simultaneously ...

Routing algorithms are required to guarantee the various quality-of-service (QoS) characteristics requested by the wide range of applications supported by Broadband Integrated Services Digital Networks (B-ISDNs). In this paper the routing problem is formulated as a fuzzy multiobjective optimization model. The fuzzy approach allows for the inclusion and evaluation of several criteria simultaneou...

Satellite communication systems are the means of realizing a global broadband integrated services digital network. Due to the statistical nature of the integrated services tra c, the resulting rate uctuations and burstiness render congestion control a complicated, yet indispensable function. The long propagation delay of the earth-satellite link further imposes severe demands and constraints on...

The evolution towards the Broadband Integrated Services Digital Network (B-ISDN) is influenced by many factors. The most significant one is the emergence of a great number of services requiring different levels of QoS and bandwidth availability. The main services are video on demand (VoD), videoconference, data and voice transfer. It is particularly important to ensure quality of service in cri...

The Broadband Integrated Services Digital Network (B-ISDN) supports transmission of different types of data such text, audio, images, video and combination of these types of data at higher transmission rates. The Asynchronous Transfer Mode (ATM) has been widely accepted as transfer mode for B-ISDN. Traffic management and congestion control are main issues in ATM networks. In this paper, we desc...
