Abstract

Today many devices contain hardware to transmit data across the internet via cellular, WiFi, and wired connections. Many of these devices communicate by using a protocol known as Transmission Control Protocol (TCP). TCP was developed when network resources were expensive, and it was rare for a typical network-aware device to have more than one connection to a network. An extension to TCP known as Multipath TCP (MPTCP) was developed to leverage the multiple network connections to which devices now have access. While the MPTCP extension has been successful in its goal of using multiple network connections to send data simultaneously, MPTCP presents new challenges. Scheduling data to be sent across multiple network connections with varying network conditions can result in data arriving out of order, adding increased system overhead and network latency. This paper presents the challenges of MPTCP packet scheduling and summarizes a proposed solution that has been found to increase performance over existing MPTCP scheduling methods.
