In Korea, Smartphones Use Multipath TCP To Reach 1 Gbps

Posted by timothy on from the modern-life dept.

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.

    In Korea, single-path TCP is only for old people.

    Got it.

    So you can exceed your monthly bandwidth quota in an hour or less and be charged for overage in record time.

      Quotas are an Australian "feature" also. Likely also a New Zealand thing.

      With multipath TCP, I can hit my quota on the DSL link, the DOCSIS based link, and the cellular link, all simultaneously.

      Quotas are an American thing. They aren't that common in other places of the world.

      China has quotas on all mobile connection providers, but not on home connections. Australia has them on absolutely anything, unless you pay an exorbitant price.

      The countries around me that I know of are: Afghanistan, Bahrain, Iran, Iraq, Tajikistan, Azerbaijan, Armenia, Pakistan, China, Russia and UAE. They all have quotas (most of their ISPs, some provide services with no quota that are not very affordable). It's essentially every country that snoops. More gigabytes means more CPU.

    The advantage of MPTCP is you can keep your existing TCP-connection alive when you are roaming.

    The people working on this have captured a single TCP-connection being kept running for longer than a day on a roaming device.

    If there's a "pancake face", it's Americans who wear too much makeup, or perhaps Americans who overindulge at IHOP, Bob Evans, and Denny's. And any country is a "gook", as guk is just the Sino-Korean word for a country, akin to Mandarin guó, Sino-Japanese koku, and Vietnamese quô'c.
