T. Engel Siemens AG Munich Germany Increasing End-to-End Availability over Multiple Autonomous Systems

Abstract — This paper presents a coordinated approach for increasing the end-to-end availability of inter-domain paths. Major reasons for intermittent failures are frequent inter-domain route changes and their long convergence times. The first part of our solution reduces the need for inter-domain path changes by introducing the Resilient Chain. The two other mechanisms — Fast Scoped Rerouting and Virtual Convergence — are intended to limit the impact of BGP rerouting

Speeding up Transaction-oriented Communications in the Internet

Abstract: Future mobile networks will offer a great variety of multimedia services. DiffServ is the promising framework standardized by the IETF to enhance the Internet with the essential quality of service. Unfortunately, transaction-oriented applications— the most popular class of applications—are not sufficiently supported yet. Quick Forwarding (QF) has been proposed to fill this gap between Expedited Forwarding and Assured Forwarding. In this paper, 1 we present a scalable QF Per-Domain Behaviour using a set of simple but effective traffic conditioning functions. Our approach enables ISPs to provide end-to-end services suitable for transaction-oriented communications while utilizing their network resources efficiently.
