We propose a peer-to-peer multimedia streaming solution based on the
BitTorrent content-distribution protocol. Our proposal includes two
modifications that allow it to deliver multimedia data on time. First,
we replace the rarest-first chunk downloading policy of BitTorrent
by a policy requiring peers to download first the chunks that they
will watch in the near future. Second, we introduce a new randomized
tit-for-tat peer selection policy that gives free tries to a larger
number of peers and lets them participate sooner in the media distribution.
Our simulations indicate that both changes are required to achieve
a good streaming quality.
