Apple iOS 7 surprises as first with new multipath TCP connections

Apple's iOS 7 is the first large-scale use of a newly-minted Internet protocol, called multipath TCP. It lets computers send and receive data across different network paths and interfaces at the same time, such as Ethernet, Wi-Fi and 3G.There is evidence [see screen shot below that Apple is using the new protocol for iOS 7 device links to Siri, Apple's cloud-based, natural language voice command and navigation service. MPTCP is intended to create more robust connections, resistant to path failures, and to improve performance, especially for delay-sensitive applications such as voice. It's part of an ambitious, global effort to transform the Internet from a mainly data network today to one that supports far more demanding applications such as telephony and IP TV.The new protocol has been in the works for several years, and became an "experimental standard" of the IETF in January, as RFC 6824. Six months later, three implementations had been
