Voice and Video over IP Protocols and Technologies

Quad Play (voice, video, data and wireless) is the name of the game for the latest evolution in the communications industry. IP networks are the base on which these service are converging to deliver rich multimedia services to the consumer and enterprises. More personnel will be responsible for operating, maintaining and working with IP-centric networks. This course provides essential knowledge on voice and video services using IP (VoIP) in communications networks. We begin the course with an overview of the motivation and network architectures of today and tomorrow. We then provide an end-to-end view of call setup to establish voice and video services over IP networks. The course includes several exercises to reinforce key objectives. Throughout the course major protocols and technologies such as IP multicasting, SIP, Megago, IGMP, RTSP, SAP, SDP, RSVP, RTP, RTCP, MPLS, ROHC, etc. are discussed as appropriate.

Learning Objectives

After completing this course the student will be able to:
• List the motivations of delivering voice and video over IP
• Sketch the changes in network architecture for VoIP
• Outline the steps to setup a VoIP call and a video call
• List and discuss key protocols used in edge (access) networks
• List and discuss key protocols used in core networks
• Describe the requirements of QoS for real-time IP transport
• Sketch QoS solutions for voice & video in IP networks
• Analyze the interworking of VoIP with legacy networks
• Discuss authentication and authorization for VoIP
• Identify access independent (core) functions
• Identify access dependent functions
• List security threats and solutions for VoIP networks
• Identify Key Performance Indicators (KPI) for VoIP
• Analyze capacity planning

Intended Audience

This course is intended for those familiar with circuit-switched networks, IP-based data networks and wireless networks.

Suggested Prerequisites

• Welcome to IP Networking (eLearning)
