“…Hence core routers do not need to perform any QoS control operations, besides simple queueing operations. Examples of this approach are [64], [65], [66], [67], [68], [69], [70]. Most of schemes are designed for DiffServ, and aim to provide some reasonable QoS assurances (not deterministic guarantees we discussed so far) for adaptive applications such as Internet audio and video streaming.…”

Abstract-We survey recent advances in theories and models for Internet Quality of Service (QoS). We start with the theory of network calculus, which lays the foundation for support of deterministic performance guarantees in networks, and illustrate its applications to integrated services, differentiated services, and streaming media playback delays. We also present mechanisms and architecture for scalable support of guaranteed services in the Internet, based on the concept of a stateless core. Methods for scalable control operations are also briefly discussed. We then turn our attention to statistical performance guarantees, and describe several new probabilistic results that can be used for a statistical dimensioning of differentiated services. Lastly, we review recent proposals and results in supporting performance guarantees in a best effort context. These include models for elastic throughput guarantees based on TCP performance modeling, techniques for some quality of service differentiation without access control, and methods that allow an application to control the performance it receives, in the absence of network support.

“…In the endpoint admission control scheme designed by Elek et al [64], an end host sends probe packets at the rate it wishes to reserve. The probe packets are queued at a separate lower priority queue at routers.…”

“…To provide guaranteed services, existent proposals tend to require significant network state information and, in many cases, changes in all network nodes [6]. To provide predictive services, control tasks based on network measurements performed node-by-node [7,8] and end-to-end [9,10] have deserved special attention. These solutions lead to reduced control information and overhead, but eventually to QoS degradation.…”

Abstract. The use of Internet as an ubiquitous communication platform puts a strong demand on service providers regarding the assurance of multiple service levels consistently. Designing flexible and simple service-oriented management strategies is crucial to support multiconstained applications conveniently and to obtain a deployable and sustainable service quality offer in multiservice IP networks. In this context, this paper proposes the use of a self-adaptive QoS and SLS management strategy sustained by a service-oriented traffic admission control scheme to ensure the negotiated quality levels. A proof-of-concept of the proposed strategy is provided, illustrating its ability to self-adapt and control efficiently distinct QoS requirements in multiservice IP networks.

“…The literature in application-layer admission control includes end-to-end measurement-based admission control (EMBAC) [3,6,12] and distributed admission control [9,11]. In EMBAC schemes, before transmission of user data, an end-system first sends probe packets to the receiver.…”
