A web service-based network composition architecture for the next generation internet (original) (raw)

Performance Analysis of Network Composition in Ambient Networks

2007 Brazilian Networking …, 2007

Currently, resource sharing and service offering remains subject to troublesome, manual configuration and to extensive, previously established agreements. Ambient Networks have emerged to facilitate cooperation between heterogeneous networks, usually among different administrative domains and technologies. This cooperation can be achieved with the adoption of a new key networking concept which is called by composition. The performance of the composition is a key factor for determining the feasibility of Ambient Networks, since it is expected to be extensively used during a typical interaction between a user and the network, itself. This paper presents a network composition simulator and a performance evaluation that uses a voice service aimed for supporting the demands for composition. The obtained results show that, for the scenario which is under consideration, composition does no represent an obstacle when supported by a voice service.

Dynamic and automatic interworking between personal area networks using composition

2005

Next generation communication networks will be characterized by the coexistence of multiple technologies and user devices in an integrated fashion. The increasing number of devices owned by a single user will lead to a new communication paradigm: users owning multiple devices that form cooperative networks, and networks of different users that communicate with each other, e.g., acquiring Internet access through each other. In this communication scenario no user intervention should be required and technology should seamlessly adapt to the user's context, preferences, and needs. In this paper we address one of those scenarios, interworking between Personal Area Networks, using legacy technologies and the Ambient Network and Network Composition concepts, herein explained. We argue that new functionalities should be introduced to enable effortless use of legacy technologies in such dynamic and heterogeneous environments.

Business Implications of Composition Framework in Ambient Networks

2000

This paper presents initial findings on how Ambient Networks technology will enable new ways to establish and manage access and service provisioning from a business perspective. A concept called network composition, developed in phase 1 of the Ambient Networks project provides the basic framework for ambient networking meaning that "any" user will be able to connect to "any" network implying

Networks for Pervasive Services: Six Ways to Upgrade the Internet

"Sample chapter "A Peek at the Future Internet" available at http://www.springer.com/978-94-007-1472-4 << Beautifully written, this book takes the reader on a compelling tour of the state of affairs in today’s Internet and the challenges it faces for supporting pervasive services of tomorrow. The approach adopted by the authors looks at the big picture, discussing the evolution of the Internet from a rigidly defined layered architecture to an interactive multi-faceted system providing, beyond connectivity, a more generative next-generation network infrastructure. In this context, the authors describe a selection of some of the prominent network mechanisms that may help in shaping the architecture of the future Internet. Overall, this book is informative, enjoyable, and an excellent reference source for every student, network professional, or researcher interested in the post-Internet era. >> Prof. Raouf Boutaba, University of Waterloo (Canada) Since its inception in the 1970s the Internet has become larger, faster and wireless. It is the biggest machine ever built, the “generative” engine of our digital society. However, the software that runs the global network has not seen any substantial upgrade since the early 1990s. It is now evident that the existing mechanisms that transport data around the Internet are no longer adequate for the new breed of Web applications. This book explains why the time is ripe for a complete overhaul in view of the Future Internet. Through a series of simple examples, the authors present a wealth of network mechanisms, starting from those that sustain the Web today. Readers will become familiar with a range of advanced protocols that will make the Internet more ubiquitous, reactive, proactive, information-driven, distribution-efficient and searchable. This book presents a selection of remarkable research ideas, making them accessible to the non-specialist reader. TABLE OF CONTENTS Foreword Preface Acknowledgements 1.

Scenarios for a Future Internet based on Cross-Layer Functional Composition

2010

Functional composition is an approach of a future Internet architecture that decomposes the network stack in functional blocks that can be dynamically composed upon connection request. This decomposition resembles the idea of web and telecommunication service in the SOA world. In this paper we will present an architecture to integrate functional blocks from different domains and describe different communication scenarios that demonstrate the advantages and flexibility of such an approach.
