Dynamic Allocation of Servers to Jobs in a Grid Hosting Environment
BT Technology Journal - Tập 22 - Trang 251-260 - 2004
As computational resources become available for use over the Internet, a requirement has emerged to reconfigure servers to an optimal allocation to cope with an unpredictable flow of incoming jobs. This paper describes an architecture that allows the dynamic reconfiguration of servers to process incoming jobs by switching servers between conceptual pools. The system makes use of heuristic policies......
Edge Mobility Architecture — Routeing and Hand-off
BT Technology Journal - Tập 19 - Trang 114-126 - 2001
This paper presents a network architecture for supporting edge mobility, and goes on to consider IP networks in which the core topology is fixed but where the hosts at the edge of the network may be mobile, as is the case in cellular networks. Within this architecture, mobile enhanced routeing (MER) protocols are used to support the prefix-routed requirements of the fixed Internet, along with the ......
Emerging Broadband Access Technologies
BT Technology Journal - Tập 16 Số 4 - Trang 187-195 - 1998
This paper briefly outlines the wide variety of emerging technologies that are set to challenge the traditional copper pair access network for new services. Features such as capacity and geographical coverage of the alternatives are discussed.
Out and About — Real World Teleconferencing
BT Technology Journal - Tập 18 - Trang 80-82 - 2000
Videoconferencing has traditionally been confined to desktop or office environments. However, a large percentage of the workforce is engaged in mobile occupations away from the desktop. In this paper we describe how augmented reality can be used to develop new forms of teleconferencing to support these workers. To provide an example of one approach, we have developed an augmented reality system th......
Guaranteed QoS synthesis — an example of a scalable core IP quality of service solution
BT Technology Journal - Tập 23 Số 2 - Trang 160-170 - 2005
A Distributed Framework for Parallel Data Mining Using HPJava
BT Technology Journal - Tập 17 - Trang 146-154 - 1999
Java has become a language of choice for applications executing in heterogeneous environments utilising distributed objects and multithreading. To handle large data sets, scalable and efficient implementations of data mining approaches are required, generally employing computationally intensive algorithms. Conventional Java implementations do not directly provide support for the data structures of......
Video QoS enhancement using perceptual quality metrics
BT Technology Journal - Tập 23 - Trang 208-216 - 2005
As the market for broadband video services matures, the ability to deliver high-value video content will become increasingly important. For the telecommunications industry to compete effectively with other video providers, it is vital that the quality of video services matches the expectations of customers. A major challenge lies in ensuring that the trade-off between price and quality is acceptab......
OSS Responsibilities
BT Technology Journal - Tập 18 - Trang 78-79 - 2000
We are all familiar with technological advances that have transformed the telecommunications industry in recent history. Why, it was only last millennium that the simplicity of digital signalling replaced the click-whirr of analogue pulses. With all these advances, we have taken for granted that sophisticated mechanisms exist behind the scenes to support the operation of the services we use. Your ......
