This software is a simulation of the Gnutella Ping Pong protocol (Official Website). Gnutella is a Peer-2-Peer protocol, used the share information across the network. The Ping-Pong protocol is used for discovering new nodes across the network.
The simulation is written in Java ad use the Java Threads Objects.
For better understanding the workflow of the simulation you can read:
For executing the simulation you must execute the following steps
git clone git@github.com:cortico/p2p-pingpong.git
cd p2p-pingpong/
ant buildThen you can choose from 3 different Ping Pong Implementation
| Implementation | Description |
|---|---|
| Simple | That use the simple ping pong algorithm (without caching) |
| Cache | That use the cached version of ping pong algorithm |
| Refined | That use the refined version of pong caching algorithm |
And then execute with
ant <implementation>
You can define the network overlay using the files:
- peer_gen for defining the peer list:
p1
p2
p3
p4
...
- connect_gen for defining the connection list:
p0;p4
p0;p5
p0;p9
p0;p10
...
- dyna for defining the dynamics:
n1;p0
sleep;1
n2;p3
sleep;1
n3;p6
Where sleep;x means that the execution will wait for x seconds and n1;n2 means that a new node n1 connects to te overlay through n2 (please note that new node does not need to appear in the peer_gen file.
You can use other files for your simulation with the command
ant <mode> -Dpeer="<peerfilename>" -Dconn="<connfilename>" -Ddyna="<dynafilename>"
