Multipath TCP is a major extension to TCP that allows improving the resource usage in the current Internet by transmitting data over several TCP subflows, while still showing one single regular TCP socket to the application. This document describes our experience in writing a MultiPath TCP implementation in the Linux kernel and discusses implementation guidelines that could be useful for other developers who are planning to add MultiPath TCP to their networking stack. Status of this Memo This Internet-Draft is submitted in full conformance with the provisions of BCP 78 and BCP 79. Internet-Drafts are working documents of the Internet Engineering Task Force (IETF). Note that other groups may also distribute working documents.
