We propose a video streaming system that uscs many ordinary computers (peers) as servers, which is less costly and more scalablc than using a single or a few dedicated servers. To circumvcnt frcqucnt peer disconnccts and limited peer up-link bandwidth, each video is coded into multiplc descriptions, which are distributed over multiple peers. The system serves a client request by streaming multiple dcscriptions of tlic requcsted video from separate peers. Using the MD-FEC coding scheme, and

... e models for pcer disconnects, reconnects and for searching replaccment serving peers after a pcer disconncct, we simulated video strcaming in such a system. Our results show significant benctits.in using a large number of descriptions and serving peers.
