Software-defined home networking devices for multi-home visual sharing

Existing home-networking protocols do not robustly incorporate universal connectivity among multiple homes, which leaves their use restricted to a single home. In addition, even in a single home network, new functional requirements ask for more diversified forms of networking control. This paper presents in-home consumer electronic devices that incorporate the emerging SDN (Software Defined Networking) paradigm. The proposed devices enable ondemand provisioning for protocol-agnostic home networking and thus provide a high degree of flexibility for intra-home networking as well as wider connectivity for inter-home networking. The feasibility of the prototype devices is verified by realizing a multi-home visual-sharing scenario and by supporting diverse future scenarios.
