Since getting the iPhone, i've been curious as to how this works.


I have one simple question really:

With the push notifications, if you have multiple apps using PUSH, does the phone have multple connections to a whole lot of different severs? or does it just have one connection, to one server, and then from that server it goes to the apps server?


I hope that actually just made sense.. it did in my head at least, but that doesn't mean a lot lol.

No, the phone has one, constant connection to Apple in which all notifications go through.


X application -> Apple's servers -> You.


So multiple applications would send their desired notifications to Apple which send them via the one connection to you.

JAMMAN2110: Have a look here for some info: http://en.wikipedia.org/wiki/Apple_Push_Notification_Service :)


Hi thanks for the link

Still isn't quite clear though as to whether its like one connection to an apple sever, then to third parties. or whether its one connection per app, to any server that is speficied by the app maker?

Ahh fantastic. That's what I thought, but wasn't sure.


Thanks for that.

Apple has had problems getting Push notifications stable and to scale as per here

along with the MobileMe issues which Apple originally tagged as 'Exchange for the rest of us'

(Meanwhile Microsoft tested Exchange 2010's scalability by putting 10 Million mailboxes on the service. :-)




Tyler - Parnell Geek - iPhone 3G - Lenovo X301 - Kaseya - Great Western Steak House, these are some of my favourite things.

Never had issues with PUSH services as of yet.

oh, and I've never used MobileMe - I have an Exchange 2007 account, seems to work well.



Oh PS: we all know that the Tagline of MobileMe is rubbish. It's not Exchange for the rest of us at all. Lol.
