Tech could be introduced next week
Future Time Capsules could be used to automatically cache updates for Macs and iOS devices, a report suggests. Apple is said to be testing the concept internally; in practice, a Time Capsule would learn which devices connect to it, and fetch updates in advance. If a person chose to install an update, the router would then use the local copy, 9to5 said, rather than start a new download.
The scheme is similar to one employed by Mac OS X Server, which would make it relatively easy to extend. It is also similar to technology employed by some BitTorrent-enabled NAS routers, which can be configured to download files overnight without connected computers being on. In Apple's case, it would allow some updates to be installed almost instantaneously.
Apple is currently said to be low on stock for at least the Time Capsule and the AirPort Extreme, although there are now conflicting reports about the AirPort Express. The company could be preparing to upgrade its routers to use update caching and/or 450Mbps peak speeds, matching the technology in 2011 iMacs and MacBook Pros. An announcement could be made at Apple's June 6th WWDC keynote.
