Hi all,
I am implementing the 3 node batman-adv network.
A <---> B <---> C
B is the relay point for communication between A and C.
The connection is 802.11 or ethernet? Does B have two separate interfaces to comunicate with A and B and partecipating to the mesh?
I have setup the batman-adv 2011.1.0 in all nodes and succesfully I can communicate and also use avahi between all nodes.
Now I want to calculate bandwidth, jitter and throughput patterns.
To calculate bandwidth, I used iperf -s on machine A.
On machine B, I used iperf -C <ip address of A> This gave me a bandwidth of 89.1 Mbits/sec
On machine C, I used iperf -c <ip address of A> This gave me a bandwith of 89.0 Mbits/sec
Since, there is relay through B to reach C, I was expecting the bandwith from A to C to be less around half (say 50 Mbits/sec). Is my understanding correct?
From what you are saying I deduce that you are using ethernet cables.
So 89 Mb/s is a perfectly valid result since ethernet is full duplex, this mean that node B can receive and send packet at the same time (this is not possible in wireless network).
Please help me.
