DESCRIPTION:Distributed protocols for peer to peer file sharing\, streamin
 g video\, and video on demand have revolutionised the way the majority of 
 information is conveyed over the Internet. The peers are millions of compu
 ters\, acting as both clients and servers\, downloading and uploading info
 rmation. Information to be shared is broken into chunks\, and the chunks a
 re traded among peers in the network. There can be turnover in the set of 
 chunks of information being collected and/or in the set of peers collectin
 g the information. Coding\, in which groups of chunks are combined to form
  new chunks\, can enhance the collection process. The systems are distribu
 ted and scalable. The theory for understanding peer to peer systems has la
 gged far behind our ability to mathematically model\, predict\, and optimi
 ze system performance. In this talk I shall discuss stochastic models\, ma
 thematical results\, and challenges relating to the performance of peer to
  peer communication in large networks.
