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 applicationsthe 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.
