Re: [WIRELESS-LAN] Favorite wireless tweaks?
Bruce, Did you guys go all the way and enable 802.11r as well? (Make - before - break roaming) If you did, did you have any older device's not tolerate the changes to the TLV's?

No configuration at all needed on the client: apple sends the clients to you. Swa To install it: use any mac, add the OS X Server app from the app store (costs a few dollars, guess around 20$ or so (I only see prices in EURO) Once you have that, you can enable the cache service It'll register with apple and apple will redirect clients on your network to the cache instead of their servers when it recognizes the source IP as the same as the registered cache. There's no need to configure anything on the devices themselves. Advanced configurations might be needed on more complex networks. See here for command line options: http://support.apple.com/kb/HT5590 Esp. if you have multiple outside IP addresses, or internal firewalls between the clients and the server, ... you need to do more than just turn on the service.

We peaked at just over 9.5Gbps today on our campus (30 second averages). Jason On 09/18/2013 01:29 PM, Eric T.

RE: [WIRELESS-LAN] Bandwidth utilization and IOS7 upgrade
We haven't seen a spike as such, but that’s probably due to the time it was released since we are in Aus. Certainly our app id on the firewalls now shows itunes-base has the largest bandwidth user, it's gone from number 37 yesterday to number 1 since IOS7 release today 6.5 hours -- Jason Cook Technology Services The University of Adelaide, AUSTRALIA 5005 Ph : +61 8 8313 4800
