Proactive Resource Provisioning for Voice over IP

چکیده
This paper presents a dynamic Service Level Agreement (SLA) negotiation scheme between peer autonomous systems (ASes) that implement DiffServ per domain behaviors. For concreteness, we tailor our scheme to account for the needs of VoIP transport across multiple ASes. We present a heuristic but computationally simple and distributed scheme that uses traffic statistics to forecast the near-future demand. Our scheme provides a statistical guarantee on the renegotiation frequency and blocking probability. Simulations demonstrate that it achieves more efficient usage of the reserved bandwidth than would be accomplished by using the de facto static SLA negotiation schemes.

Simulation of VoIP over UDP with Bandwidth on Demand Analysis
This paper analyses resource provisioning for enterprise Voice-over-IP (VoIP) networks. Simulation and analytical methods are used to enhance the provisioning process, which ultimately aims to provide the Bandwidth and its availability. This paper defines simple guidelines for network dimensioning in a multimedia environment in terms of end-to-end delay for the voice traffic, and in terms of th...
متن کاملNetwork Provisioning & Resource Management for IP Telephony1
The rapid growth of IP-based packet switched network and the overall bandwidth efficiency of an integrated IP network make it an attractive candidate to transport real time voice connections. However, high quality voice over IP (VoIP) remains a challenge because interactive voice imposes many performance requirements (such as loss rate and latency) on the transport network. This cannot be easil...

Allocating resources in networks to QoS flows may require undesirable delays or costs. We consider a dynamic Service Level Agreement (SLA) negotiation scheme between peer autonomous systems (ASes) that implement DiffServ per domain behaviors. For concreteness, we tailor our scheme to account for the needs of Voice over IP transport across multiple ASes. We present a heuristic but computationall...
متن کاملUncertain Resource Availabilities: Proactive and Reactive Procedures for Preemptive Resource Constrained project Scheduling Problem
Project scheduling is the part of project management that deals with determining when intime to start (and finish) which activities and with the allocation of scarce resources to theproject activities. In practice, virtually all project managers are confronted with resourcescarceness. In such cases, the Resource-Constrained Project Scheduling Problem (RCPSP)arises. This optimization problem has...
متن کاملImplementation of QoS-Provisioning System for Voice over IP
In this paper, we address issues related to implementing Voice-over-IP (VoIP) services in packet switching networks. VoIP has been identified as a critical real-time application in the network QoS research community and has been implemented in commercial products. To provide competent quality of service for VoIP, the call admission control (CAC) mechanism has to be introduced to prevent packet ...
