The Internet has been growing exponentially and continues to evolve to accommodate an increasingly large number of applications with diverse service requirements. A remarkable aspect of this evolution is the convergence of real-time communications services with traditional data communications services over the Internet. In particular, Internet Telephony, or Voice Over IP is one of the most promising services currently being deployed. While there are many benefits to Voice over IP such as cost effectiveness and enhanced features, there exist a number of barriers to the widespread deployment of Internet Telephony. The purpose of this course is to provide in-depth understanding of the concept and operation of Voice Over IP and discuss issues and strategies to address the issues. In this course, students will gain understanding of how to adapt an IP packet network, which is basically designed for data, to provide wide-area voice communications. Topics include telephony fundamentals, Voice Over IP concepts, adapting IP networks to support voice, H.323 and SIP signaling protocols, QoS issues in IP networks, IETF standards, and network management.
