Towards switched-homing for Internet access

Most home networks are single-homed, i.e. connected through a single link to the Internet. This solution, while easy to deploy, lacks resilience because of its single point of failure. BGP-based multihoming is suitable for entreprise networks, but impossible for home networks. We encourage the IETF and researchers to explore an alternative called switched-homing where a small network can switch from one Internet link to another. This paradigm can increase network resilience and provide energy savings by switching to a lower consumption link at appropriate times. We show that such switches can be smooth using modern transport protocols like QUIC and Multipath TCP, and discuss future work.
