Network Systems Colloquium

In this talk we will provide an overview of an architecture of today's Internet streaming media delivery networks and will discuss various problems that such systems pose with regard to coding of audio/video information and network traffic control algorithms. For example, we will demonstrate that such factors as media distribution model (live or on demand), type of routing (unicast vs. multicast), and network optimization criteria (e.g. minimization of distortion for given statistics of packet loss and connection rates, minimization of (internal) traffic in the delivery network, etc.), may lead to several (distinct) types of communication problems, requiring different treatment from both source and channel coding perspectives. We will explain how some of these problems can be addressed by adapting the conventional scalable video and audio compression schemes and using channel adaptation (congestion and error-rate control) algorithms in client and server components of the streaming media software.
