The concept of Software Defined Networking (SDN) has been successfully applied to efficiently configure and manage network infrastructure, e.g. in the context of data centres or WANs, and increasingly for ubiquitous communication. In this paper, we explore the idea of pushing SDN to the end-host. In particular, we consider the scenario of load balancing across multiple host network interfaces. We have explored and implemented different SDN-based load balancing approaches based on OpenFlow software switches, and have demonstrated the feasibility and potential of this approach.
