04 Try it yourself Interactive

One file, four peers, two arrangements

The same 300 MB recording from section 02, written here as 3 units of 100 MB, and the same four laptops. One round is the time one machine needs to push one complete copy across its uplink, which at 100 Mbps is 24 seconds. Client server lets only the server upload. Peer to peer lets any laptop that holds the file upload it too. Watch the fourth stat in one run and the second stat in the other. Nothing plays on its own: Next, Back and Reset, or the arrow keys.
