In Korea, Smartphones Use Multipath TCP To Reach 1 Gbps
An anonymous reader writes: Korean users are among the most bandwidth-hungry smartphone users. During the MPTCP WG meeting at IETF'93, SungHoon Seo announced that KT had deployed since mid June a commercial service that allows smartphone users to reach 1 Gbps. This is not yet 5G, but the first large scale commercial deployment of Multipath TCP by a mobile operator to combine fast LTE and fast WiFi to reach up to 1 Gbps. This service is offered on the Samsung Galaxy S6 whose Linux kernel includes the open-source Multipath TCP implementation and SOCKSv5 proxies managed by the network operator. Several thousands of users are already actively using this optional service. -

A Little-Heralded New iOS 7 Feature: Multipath TCP
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." -

A 50 Gbps Connection With Multipath TCP
First time accepted submitter Olivier Bonaventure writes "The TCP protocol is closely coupled with the underlying IP protocol. Once a TCP connection has been established through one IP address, the other packets of the connection must be sent from this address. This makes mobility and load balancing difficult. Multipath TCP is a new extension that solves these old problems by decoupling TCP from the underlying IP. A Multipath TCP connection can send packets over several interfaces/addresses simultaneously while remaining backward compatible with existing TCP applications. Multipath TCP has several use cases, including smartphones that can use both WiFi and 3G, or servers that can pool multiple high-speed interfaces. Christoph Paasch, Gregory Detal and their colleagues who develop the implementation of Multipath TCP in the Linux kernel have achieved 50 Gbps for a single TCP connection [note: link has source code and technical details] by pooling together six 10 Gbps interfaces." -
