Apple iOS 7 surprises as first with new multipath TCP connections

John Cox | Sept. 20, 2013
iOS 7 first large-scale, commercial use of resilient TCP extension.

"Packet traces collected on an iPad running iOS7 reveal that it uses Multipath TCP to reach some destinations that seem to be directly controlled by Apple," he wrote in a blog post. "You won't see Multipath TCP for regular TCP connections from applications like Safari, but if you use SIRI, you might see that the connection with one of the apple servers runs uses Multipath TCP."

We don't yet know how Apple is using MPTCP. "At this stage, the actual usage of Multipath TCP by iOS 7 is unclear...." says Bonaventure. "The next step will, of course, be the utilization of Multipath TCP by default for all applications running over iOS7."
