Re: iPhone and Network Disruptions ...

Hank, Warren, & Fellow Nanogers:

Looking at this issue with an 'interoperability lens,' I remain puzzled by a personal observation that at least in the publicized case of Duke University's Wi-Fi net being effected, the "ARP storms" did not negatively impact network operations UNTIL the presence of iPhones on campus.  The nagging point in my mind therefore, is: why have other Wi-Fi devices (laptops, HPCs/PDAs, Smartphones etc.,) NOT caused the 'type' of ARP flooding, which was made visible in Duke's Wi-Fi environment?   Why did this issue become MOST prominent with the introduction of Apple's iPhone on campus?

In that sense, my original question regarding iPhone's 'unique' operational circumstance(s) will have/need to be considered. Initial analysis tells me that we may not be far into that aspect but, we might need to... 

Again, I wish to thank you for the responses.

All my best,
Robert.
