Abstract

ISBN 978-1-61520-791-1; The Internet is an interconnection of multiple networks called domains. Inter-domain routing is ensured by BGP which preserves each domain's independence and announces routes arbitrarily chosen by domains. BGP messages carry no information concerning quality [...]

Abstract

International audience; In this contribution, we consider a novel approach for efficiently supporting IP packets directly into a slotted optical wavelength- division-multiplexing (WDM) layer with several quality of service (QoS) requirements. The approach is based on aggregating IP [...]

Abstract

International audience; Optical Packet Switching (OPS) is among the most promising solutions for next generation metropolitan networks. The increase of packet-based services (video on demand, etc.) is pushing metropolitan networks providers to renew their infrastructures. Today, metropolitan [...]

Abstract

International audience; Message from the Program Chairs We are delighted to welcome you to the 27th edition of the International Conference on Real-Time Networks and Systems (RTNS), in Toulouse, France. RTNS is a friendly conference with a great sense of community that offers excellent [...]

Abstract

The book presents mechanisms, protocols, and system architectures to achieve end-to-end Quality-of-Service (QoS) over heterogeneous wired/wireless networks in the Internet. Particular focus is on measurement techniques, traffic engineering mechanisms and protocols, signalling protocols [...]

Abstract

The continuous growth of the urban population has generated a drastic expansion of our cities. Nowadays, indeed, more than 50 % of the world’s population is urban, and they forecast that it will reach 70 % by 2050. Therefore, cities need to be ready to accommodate this huge amount [...]

Abstract

MPLS DiffServ-TE presents the solution awaited so much by the network service providers by allowing a differentiation of services and a traffic engineering based on a fast packet switching technology. However, the management of such a network is not a simple function and could not [...]

Abstract

We propose a novel technique for answering routing queries in public transportation networks that allows unrestricted walking. We consider several types of queries: earliest arrival time, Pareto-optimal journeys regarding arrival time, number of transfers and walking time, and profile, [...]

Abstract

Energy consumption has already become a major challenge to the current Internet. Most researches aim at lowering energy consumption under certain fixed performance constraints. Since trade-offs exist between network performance and energy saving, Internet Service Providers (ISPs) [...]

Abstract

Multi-Protocol Label Switching (MPLS) is a network layer packet forwarding technology that provides flexible circuit switched traffic engineering solutions in packet switched networks by explicit path routing. However, the actual weakness of MPLS resides in its inability to provide [...]
