The migration of the Internet from classic computer communication to a platform for multimedia applications with real-time communication requires end-to-end improvements of the network-level service. The proposal known as Differentiated Services is a very promising approach for implementing quality of service in the Internet and is being discussed and developed. The challenge is to deliver end-...

This paper describes the design of a video see-through augmented reality system for active safety testing. The development is explained in detail, with focus on the design considerations for the different subsystems. It is shown that it is possible to build a system using available commercial off-the-shelf components, while still maintaining the performance needed for the intended application. ...

With audiovisual and other sensory information in distributed multimedia applications, end-to-end quality of service guarantees are a major acceptance factor for these applications. We designed and implemented an end-point architecture, called OMEGA, for provision of end-to-end QoS guarantees. This architecture relies on a distributed QoS management entity, called the QoS Broker, to translate, ...

End-user focused end-to-end Service Delivery Platform offerings are key to achieving real market and revenue growth through effective partner and service lifecycle management. Rapid and efficient rollout, operation and retirement of services support true service innovation. Adopting the end-to-end approach will allow operators to service-enable their subscribers. Subscribers become empowered an...

An end-to-end data delivery protocol for dynamic communication networks is presented. The protocol uses bounded sequence numbers and can tolerate both link failures and (intermediate) processor crashes. Previous bounded end-to-end protocols could not tolerate crashes. We present a self-stabilizing version of the algorithm that can recover from crashes of the sender and the receiver as well as o...

Electronic communications devices intended for government or military applications must be rigorously evaluated to ensure that they maintain data confidentiality. High-grade information security evaluations require a detailed analysis of the device’s design, to determine how it achieves necessary security functions. In practice, such evaluations are labour-intensive and costly, so there is a st...

This paper present details of an integrated database visualization system. The system supports the visualization process from an end-to-end perspective. Included in the system is a mechanism for performing transformations to the data being visualized through the use of database relations. This mapping process provides an abstract mechanism for supporting data to geometry transformations under t...

Wireless sensor networks are conceived to monitor a certain application or physical phenomena and are supposed to function for several years without any human intervention for maintenance. Thus, the main issue in sensor networks is often to extend the lifetime of the network by reducing energy consumption. On the other hand, some applications have high priority traffic that needs to be transfer...

In this paper, we consider a feedback-basedvideo transmission system over ATM ABR service under the constraints of xed end-to-end delay. The lower bound of future available rates is obtained by the states of leaky-bucketsfor high-priorityconnectionsand the occupancy of switch buuer. Based on this bound, an upper bound of feedback rates are derived, that guarantees the end-to-end delay constrain...

Modern train control systems rely on a dedicated radio network for train to ground communications. A number of possible alternatives have been analysed to adopt the European Rail Traffic Management System/European Train Control System (ERTMS/ETCS) control system on local/regional lines to improve transport capacity. Among them, a communication system based on public networks (cellular&satellite...
