Abstract
In this paper, we are interested in providing deterministic end-to-end guarantees to real-time applications in the Internet. We focus on two QoS parameters: the end-to-end response time and the end-to-end jitter, parameters of the utmost importance for such applications. We propose a solution, very simple to deploy, based on a combination of DiffServ and mpls. The Expedited Forwarding (ef) class of the Differentiated Services (DiffServ) model is well adapted for real-time applications as it is designed for flows with end-to-end real-time constraints. Moreover MultiProtocol Label Switching (mpls), when applied in a DiffServ architecture, is an efficient solution for providing Quality of Service (QoS) routing. The results of our worst case analysis enable to derive a simple admission control for the ef class. Resources provisioned for the ef class but not used by this class are available for the other classes.
