As wireless and wireline networks mature, data usage increases, and network infrastructure and services become more IP-centric, more personnel will be responsible for managing and working with IP-centric networks. A solid understanding of IP and data communications will be essential for personnel at all levels to be effective in a data-oriented environment. This course provides the background and concepts to understand the motivations of networks converging towards IP, how VoIP services operate on top of the newly converged network, and examines SIP, the dominant VoIP signaling protocol. It discusses the challenges of transport of media (voice and video) using IP (VoIP) as the transport service in telecommunication networks. It presents the unique flavor of this challenge from the perspective of the three basic types of network for the telecommunications world: Access networks, core networks, and services networks.
Learning Objectives
After completing this course, the student will be able to: • Define IP Convergence • Explain the possible evolution paths of today’s networks • Sketch the new IP converged network architecture • List the motivations for adopting voice over IP • Outline the steps to setup a VoIP call • Describe the requirements of QoS for real-time IP transport • Sketch QoS solutions for real-time IP transport • Define and explain the use of codecs • Discuss authentication and authorization for VoIP • Explain the SIP protocol and operations for session establishment, changes, and termination • Give the correct syntax for and explain the proper use of SIP’s request and response messages • Differentiate stateless, stateful and forking proxy servers • Recognize how SIP interacts with other signaling protocols • Describe the interworking with PSTN for VoIP • Dissect SIP traces for typical SIP services including VoIP • Describe LTE and IMS at a high level
Intended Audience
This course is intended for those familiar with circuit-switched networks, IP-based data networks and wireless networks.
