An SDN Perspective on Multi-Connectivity and Seamless Flow Migration

Devices capable of multi-connectivity currently use static rules for selecting the set of interfaces to use. Such rules are limited in scope and can be counter-productive. We posit that SDN techniques can address this inefficiency. We present an approach that enables an SDN controller to manage the flows traversing the Ethernet, Wi-Fi, and LTE links in our laptop and also migrate the flows from one link to another. Our solution opens avenues that enable end-user device to negotiate with the network controllers when taking its control plane decisions.
