What is the problem?

Home networks are getting more and more complicated. In our homes, we attach a growing variety of devices including smartphones, laptops, TVs, heating controllers, loudspeakers, sensors, etc. and use high bandwidth Internet applications such as video and audio streaming, high quality video conferencing, file sharing and backup, and then operate them over unreliable Wi-Fi networks. It is not surprising that many consumers are confused and frustrated when trying to manage their home network, and trying to make it secure.  Also it is common for home networks to be poorly managed, insecure or just plain broken; Moreover it is not clear how home networks will continuously improve, after they have been deployed, to provide steadily better service to home users.
