Abstract--- We propose a cooperative patching architecture to
achieve continuous live video streaming to a set of cooperative
but unreliable end hosts. In this design, each end host caches
an initial portion of the video content before playback. It then
keeps the video that has been played out for a certain time before
discarding it. An end host maintains a list of patching parents,
and retrieves lost data from one of its patching parents. Any
end host that has the requested video content can be a patching
parent. Several parent selection algorithms are proposed and
evaluated in this paper. This architecture relieves server load by
completely shifting video patching responsibility to the client side.
Video content is replicated in multiple locations across the overlay
network to provide fast and timely data recovery. Cooperative
