1 swift: the multiparty transport protocol
2 (aka BitTorrent at the transport layer)
3 Differently from TCP, the protocol does not use the ordered data stream
4 abstraction. Effectively, it splits a file into 1KB packets and sends
5 them around. The secret sauce is Merkle hash trees and binmaps.
7 Requires libevent-2.0 or higher.
9 see doc/index.html for marketing stuff, ideas and rants
10 doc/draft-ietf-ppsp-grishchenko-swift.txt for protocol draft spec
11 *.cpp for the actual code
12 swift.cpp is the main exec file; may run as e.g.
14 ./swift -t node300.das2.ewi.tudelft.nl:20000 -h \
15 d1502706c46779d361a1d562a10da0a45c4c40e5 -f \
18 ...to retrieve video and save it to a file.
20 Alternatively, you might play with the HTTP gateway, the preliminary
21 version. First, run the seeder-tracker:
23 $ ./swift -f ~/Downloads/big_buck_bunny_480p_stereo.ogg -l 0.0.0.0:20000
24 Root hash: 7c462ad1d980ba44ab4b819e29004eb0bf6e6d5f
26 ...then you may try running the swift-HTTP gateway...
28 $ ./swift -t 127.0.0.1:20000 -g 0.0.0.0:8080 -w
30 ...and finally you may point your browser at the gateway...
32 http://127.0.0.1:8080/7c462ad1d980ba44ab4b819e29004eb0bf6e6d5f
34 If you use an HTML5 browser (Chrome preferred), you are likely to see
35 the bunny trailer at this point...
