Introduction

The aim of this course is to study the main characteristics of streaming media. We start by analyzing the existing infrastructure for distribution of multimedia content. We introduce the protocols
involved in the streaming video services and their features. We present the mechanisms to ensure minimum levels of service quality, such as Differentiated Services, Integrated Services,
and functions of queuing and policing. Finally we cover the evolution of the architecture using a client-server model towards a distributed multimedia p2p model.

Prerequisites

Queueing theory (Fundamentals of Traffic Engineering)
Networks and communication protocols (Networks & Services 1 and 2)
Medium access protocols (Data Transmission 3).
Programming Java
