Information


I´m a begginer using Iperf and I don´t completely understand how it works. I have read the user-documentation and FAQ´s, besides I have run it between 2 nodes in a LAN to see if this helps me but I still don´t get it.
Documentation says it provides throughput and bandwidth but the report only shows bandwidth?
Is this available bandwidth or throughput? 
How does Iperf calculate this bandwith? Does it take into account data link, IP, TCP/UDP headers or just data?
The bandwidth reported by the server is the bandwidth client-->server or server -->client?
The bandwidth reported by the client is the bandwidth client-->server or server -->client?
Which is the relation between the buffer length Iperf uses and the amount of data sent by nodes?
Does the command iperf -n sends the buffer data n times?
Why can the sender bit rate be changed for UDP and not for TCP?
Which is the sender bit rate for TCP?
 
I have looked for additional information on the web but nothing have answered my questions. I´ll really appreciate any help.
