    The profusion of LANs and the substantial increase in LAN traffic volume have created a demand for LAN interconnection that facilitates the move towards B-ISDN. This is an important step towards the realization of a "global communications network". In this paper, we study the performance of an interconnection scenario where servers, workstations, and LANs are interconnected by an interconnecting m... View full abstract»

    Resource management in traditional networks has been the management of scarce commodities. Recent communication technologies shed a new light on the way resources are shared by the communicating agents. The advent of high-bandwidth optical fibre and the availability of cheap, high-capacity memory chips are shifting the emphasis to the management of the inherent concurrent access to and from the in...

    Traffic analysis is the inference of information (for example, presence, absence, amount, direction and frequency) from the observation of traffic flows. This paper proposes a third-parties method to avoid the traffic direction analysis. The third parties are those network users whose obligation is 20 redirect received messages to next third party. All the messages are encrypted by the same public... View full abstract»

    DTM is an optical network with bandwidth reservation and support for dynamic reallocation of bandwidth. DTM is designed for real-time multimedia applications and for high-speed computer communication. DTM provides a service with real-time guarantees: it allows reservation of bandwidth, and has constant delay between two nodes. DTM uses a novel medium-access technique and provides a multicast chann... View full abstract»

    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (511 KB)  

    In a system of recall broadcast, each message contains a set of message identifiers called its recall set. The recall set of a message identifies all previously received messages upon which the message is based. When a message is received by a process and displayed to an external user, all messages in its recall set are also displayed to the user. The authors discuss a class of recall broadcast sy...

    Asynchronous transfer mode (ATM) broadband networks support a wide range of multimedia traffic (e.g. voice, video, image, and data). Accurate characterization of the multimedia traffic is essential, in ATM networks, in order to develop a robust set of traffic descriptors. Such set is required, by the usage parameter control (UPC) algorithm, for traffic enforcement (policing). In this paper, we pre... View full abstract»
