VoIP Network Dimensioning Using Delay and Loss Bounds for Voice and Data Applications
Overview 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 delivery of consistent Quality of Service (QoS). Consistent QoS is increasingly important in order to deliver an adequate service, as defined in terms of Service Level Agreements (SLAs). 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 throughput and packet loss for TCP data traffic. A realistic environment is modeled and simulated using ns-2. The model consists of a prioritized network in which intermediate routers perform priority scheduling to provide differentiation of Internet services.
