[R] Order of messgaes/ missing messages

[Murray Jorgensen]

The TCP protocol sends a message as a stream of packets. When packets 
are lost over a particular link in the path from the sending machine at 
ETHZ to a recipient parts of the message will be re-transmitted. A 
message sent after another message can arrive before it if it 
experiences less packet loss on its path through the network. It's 
statistical, you see!
