An analytical framework for SLA admission control in a DiffServ domain
نویسندگان
چکیده
We define an analytical approach and a methodology to determine the set of Service Level Agreements (SLA) that can be effectively supported by a DiffServ IP network. We consider the Assured Forwarding (AF) Per Hop Behavior (PHB), and, based on the SLA probabilistic description, we derive a worst-case mathematical formulation for the overbooking probability, i.e., the probability that the traffic crossing any link of a source-destination path exceeds the link capacity. We then compare analytical results with simulation of different traffic models.

An Efficient Call Admission Control for Hard Real Time Communication in Differentiated Services Network
In this paper we study hard real time (HRT) communication over a differentiated service network. Differentiated Services was proposed by IETF as a scalable QoS architecture [1]. Diffserv service providers can provide delay and bandwidth guaranteed service (as per service level agreement (SLA)) by implementing diffserv services with a fair packet scheduling algorithm like WFQ. But this QoS is pr...
متن کاملScalable Quantitative Delay Guarantee Support in DiffServ Networks Through NSIS
This paper investigates the issue of enabling scalable quantitative delay guarantee support in DiffServ networks through NSIS. A NSIS QoS Model is utilized to add the admission control framework to the DiffServ architecture and reservation-based admission control algorithms are designed for ingress and interior nodes respectively for enabling quantitative delay guarantees in a DiffServ domain. ...
متن کاملScalable QoS Assurances with Measurement-Based Admission Control
Among recent trends in Quality of Service (QoS) provisioning in the Internet is the Differentiated Services Architecture, termed DiffServ. The successful deployment of Diffserv to provide a premium QoS guarantees to network traffic requires an effective admission control mechanism, which needs to be scalable and relatively simple to implement. In this paper we present a QoS network framework wi...
