Re: [ssm] Multicast SSM throughput in 802.11

[Matthias Waehlisch <mw@fhtw-berlin.de>]

Hi Tiago,

  at some access points you can configure rate limiting/a threshold for 
multicast. Because the wlan cell is a shared segment, you have no chance 
to use IGMP snooping, but you want to suppress a 'complete bandwidth 
allocation' by the use of multicast.
