Multihoming: Scheduling, Modelling, and Congestion Window Management

Known as multihoming, devices with more than one network interface can enhance their performance capabilities by harnessing unused resources from alternative access networks. Whether it is improved reliability or sheer throughput potential, network devices will benefit from a multihomed framework. Unfortunately, our current means of guaranteeing reliability while maintaining quality control, specifically, the transmission control protocol (TCP), does not support multihoming. Despite the latter, a relatively young transport layer standard called the stream control transmission protocol (SCTP), incorporates multihoming into its design. In this tutorial, we present the state of-the-art multihoming techniques using SCTP. A comprehensive overview of three main research areas will be presented, namely: handover management, concurrent multipath transfer (CMT), and congestion window management.
