A Little-Heralded New iOS 7 Feature: Multipath TCP

Posted by timothy on Thursday September 19, 2013 @02:07AM from the this-way-and-that dept.

Olivier Bonaventure writes "Besides changes in UI, multitasking and other features that the press discusses, iOS7 also includes support for Multipath TCP. Multipath TCP is a major extension to TCP that is able to use different interfaces for the same connection. Until now, Multipath TCP has been mainly used by researchers with a modified Linux kernel. iOS7 changes that, with millions of Multipath-TCP enabled devices that can switch from 3G to WiFi without losing existing TCP connections. This is not yet the case on iOS7, which currently seems to only enable it for SIRI, but other use cases will likely appear in the future."

Re:Siri: Bad use case? by bradgoodman · 2013-09-19 03:18 · Score: 1, Redundant

Pandora I can totally see. It's the antithesis of Siri. Very long, persistent, lots of data - a continuous stream. (Though other technologies, such as fragmentation at the application/asset level are often used here too - especially for video).
As for Siri - you have quite the edge case. It is an *extremely* small window between the transmission and then reception of the Siri transaction that you lose your Wifi.
