Multiservice Networking

Contents

• Service integration motivation and principles
• Quality of Service (QoS? ): principles, parameters, architectures (e.g. Intserv, Diffserv). Traffic control and congestion avoidance mechanisms. QoS? routing. Service contracts specification. Services specification, configuration and management.
• Reliable and unreliable transport services: unicast and multicast cases. Protocols oriented to QoS? and real-time support (e.g. RTP/RTCP/RTSP). Resource reservation and signaling protocols (e.g. RSVP, H.323, SIP). Voice over IP, Video/TV over IP.

Learning outcomes

• to recognize the need for service integration and discuss the problematic of Internet QoS? ;
• to explain and exemplify current QoS? architectures;
• to evaluate and differentiate QoS? mechanisms;
• to understand the problem network congestion and mechanisms to avoid it;
• to select adequate transport services based on the characteristics of applications and user services;
• to identify, define and relate the main concepts, algorithms for supporting real-time applications with group communication and QoS? requirements;
• to identify, understand and choose the main signalling and resource reservation solutions in the Internet;
• to identify the QoS? requirements of applications and services;
• to understand theoretical and practical concepts behind services such as VoIP? and Video/TV over IP.
