Re: [opss-devel] Simulation of substreaming using OPSS

Hello Varada,

We used OPSS to simulate coolstreaming using a chunk-based approach, but
OPSS engine supports well almost any TCP based P2P algorithm.
When you call the StartDownload function you could specify which is the
data size a node must download. So basically if you want to use a node 
bandwidth capacity to diffuse a video to two children with two different
substreams, you can invoke a StartDownload procedure call on both the
children nodes specifing as download size the size of the whole original
video (no changes in the simulator engine, just need to properly handle
the issue in your "algorithm" folder).
