tap-wifi-virtual-machine.cc something is abnormal

[Tan Dang Tai]

Dear Experts!

I established the model:

LXC(left) <---> br-left <---> tap-left <---> ns 3 network <---> tap-right <---> br-right <---> LXC (right)

1. Created bridge, tap birdge by running file : /ns3.24-1/src/tap-bridge/examples/virtual-network-setup.sh

2. I follew the HOWTO to create the LXC ==> Done 

      https://www.nsnam.org/wiki/HOWTO_Use_Linux_Containers_to_set_up_virtual_networks

     I have LXC@right$ and LXC@left$

3. I run tap-wifi-virtual-machine.cc  ==> scenario: standard wifi 801.11a and datarate = 54Mbps

4. To assess the quality of ns3 network.

4.1: I installed iperf on both of  LXCs and at server run: $iperf -s -u  ;;;; at client run: $iperf -c <ip_server>-u -b <bandwidth>

4.2: Results when I adjusted bandwidth: 

          BW:           1Mbps            |   2Mbps         |        5Mbps       |    10Mbps                     

    Throughput:     0.998Mbps    |   1.02Mbps    |      1.02Mbps    |     1.02Mbps

My question: I don't why all cases are got the same throughput approximate 1Mbps, although the bandwidth is increased and the datarate= 54Mps ??

I also verified this by try CSMA: tap-csma-virtual-machine.cc and change UseBridge and UseLocal. and change datarate, All of cases are worked as expected. 

I Hope some experts can give some explanation. or If I did wrong, please give some solutions. I appreciate your help. I hope my question is not duplicate

Thank you

P/s:

I also looked for this issue on this groups, but no results. And I also see some problem about UseBridge is not supported for STA/Adhoc mode. Is this also be my problem.?

I also I find solution to use UseBridge for adhocmode by Jinxue Zhang. but, I got error

                   https://groups.google.com/forum/#!searchin/ns-3-users/tapbridge/ns-3-users/lDvGR9UbEvg/9-hr4qf2YzAJ

I also tried other mode: AP and STA 

                ==> I got same problem as many people had got
