[Ilshat Shakirov <im.shakirov@xxxxxxxxx>]

Hello!,

I just pushed new version of peersim impl of p2psp -
lp:~im-shakirov/p2psp/sim
<https://code.launchpad.net/%7Eim-shakirov/p2psp/sim>
I implemented DBS of rules (the first part, which is enough to perform the
first tests). Here is log -
https://www.dropbox.com/s/dh1cewia6ahyoiy/log.txt?dl=0

As you can see the results looks very artificially. I have implemented the
next rules:
1. Peer arrival - the new peer sends "hello" msg to splitter, then splitter
sends peer list to peer, then peer sends 'hello' message to peers from peer
list.
2. work with chunks - chunk from splitter is sending to the rest of peers
(from his peer list), chunk from peer is not reseding.
3. when peer receives chunk from unknown peer, it adds peer to its peer
list.

How I can to improve implementation? I think I should add dynamic to the
network. Any ideas? =)
