Hi, Thomas Managed to get the secured mesh up after applying the linked patch. I have managed to test the HT20 mode for secured mesh and non-secured mesh due to my embedded platform only supports Fast Ethernet. Here are the results:
Non Secured Mesh (HT20) # iperf -s -i 1 ------------------------------------------------------------ Server listening on TCP port 5001 TCP window size: 85.3 KByte (default) ------------------------------------------------------------ [ ID] Interval Transfer Bandwidth [SUM] 0.0-10.0 sec 72.0 MBytes 60.1 Mbits/sec Secured Mesh (HT20) # iperf -s -i 1 ------------------------------------------------------------ Server listening on TCP port 5001 TCP window size: 85.3 KByte (default) ------------------------------------------------------------ [ ID] Interval Transfer Bandwidth [SUM] 0.0-10.1 sec 15.6 MBytes 13.0 Mbits/sec A bit disappointed that the throughput is drop quite significantly. Confirm that the aggregation is working: Rx A-MPDU request on tid 0 result 0 Open BA session requested for 0a:0b:6b:7d:e3:b9 tid 0 activated addBA response timer on tid 0 switched off addBA timer for tid 0 Aggregation is on for tid 0 Regards, Chun-Yeow On Wed, Nov 9, 2011 at 5:13 AM, Thomas Pedersen <[email protected]> wrote: > Hi Chun-Yeow, > > Have you had any success? > > I did not have time to properly to properly test throughput in a > secure mesh laste time, but now with our ft-ht-mesh + ft-mesh-fixes > branches, I'm seeing 55.5Mb/s TCP throughput with a 243Mb/s datarate. > Throughput in the non-secure case is more like at least 100Mb/s, so it > seems we have quite a bit of overhead. > > Thomas > > On Thu, Nov 3, 2011 at 6:28 PM, Yeoh Chun-Yeow <[email protected]> > wrote: > > Hi, all > > Ok.
