Driven by competitive pressure and the desire for new service generating opportunities, major service providers have begun rolling out Voice over Internet Protocol (VoIP) services to business and consumer markets. This paper looks at the challenges of designing a converged network to support VoIP and other applications. It addresses the complexities, frameworks to support VoIP migrations, and unique performance, restoration and reliability requirements.
Key components of network design for supporting VoIP include: topological design for reliability and scalability, capacity design to support voice traffic and signaling, signaling network design, and QoS design for end-to-end quality of service objectives.
