Push Notification Server	9

Provide increased server responsiveness to clients and reduce server load with Push Notification Server.

Mac OS X Server v10.6 uses an XMPP Pubsub architecture for the Push Notification Server. XMPP Pubsub is an open standard extention to XMPP (XEP-060) that allows servers and clients to communicate as needed, rather than clients continually asking the server for updates.

A service (like iCal or mail) maintains a simple connection with the client and the service informs the client that there is new data. This differs from previous methods, where calendar or mail clients contacted the server at regular intervals, requesting data, if present.

With the previous method of notification, the server must attend to each client, regardless of whether the client has data waiting for it. By using the new push method of client updating, only clients with new data are contacted, and only as needed.

About Push Notification Server

Mac OS X Server v10.6 push notification uses the same underlying technology as iChat server, but you don’t need to run iChat on a computer that is running push notification.

Push notification is available for the following services:

ÂÂ iCal Server

ÂÂ Mail Server

Clients of these services must support push notification to make use of it. Apple’s client applications on Mac OS X v10.6, and iPhone 3.0 client applications support push notification service. Third-party client applications may support it.

Mac OS X Server v10.6 push notification is not the same system as push notification for iPhone application development. You cannot use Mac OS X Server v10.6 to host iPhone application push notification.
