Mathematical analysis of peer to peer communication networks

Newton Institute Web Seminars: newton.ac.uk/webseminars

Distributed protocols for peer to peer file sharing, streaming video, and video on demand have revolutionised the way the majority of information is conveyed over the Internet. The peers are millions of computers, acting as both clients and servers, downloading and uploading information. Information to be shared is broken into chunks, and the chunks are 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 collecting the information. Coding, in which groups of chunks are combined to form new chunks, can enhance the collection process. The systems are distributed and scalable. The theory for understanding peer to peer systems has lagged far behind our ability to mathematically model, predict, and optimize system performance. In this talk I shall discuss stochastic models, mathematical results, and challenges relating to the performance of peer to peer communication in large networks.

tv broadcasters could live air (or seed) shows on a bittorrent like video player, and eliminate server costs that traditional web media outlets are plagued with

@Jelloxox The sound is bad, but it's not so bad that you can't hear it. I could hear it just fine.

So I understood everything all the way up to where he starting explaining the formulas for the p2p pretty redonculous almost a sense of overkill for explaining p2p in a formula.

I don't see too much discussion in relation to connection speed between peers.

If you connect to a peer with a horrid upload speed it slows you down immensely.

@ihatedisney666 ??? I hear it perfectly.How cant u?

it sounds pretty good in my machine
