Thanks for your writing, very useful. I have a question on Mcast. On page 9 you recomend to enable both MCAST Rate Optimization and DMO, but also rise DMO threshold to 80. How can be preferable to use 80 TXOPs instead of broadcasting the MCAST frame at the optimized rate? Could you please point me to any reading to understand? Thanks!!!

 

[EDITED] An Aruba engineer kindly helped with this basic question. Mcast frames do not use MCS datarates and contains a single packet per PDU. DMO uses MCS datarates and many packets can be aggregated.
