alt Hacker NewsAre we not yet at a point where we could have a truly global network that uses multiple technologies and mediums to keep a user always connected?
Like seamlessly switching between Wi-Fi, nG, Bluetooth, satellite, pigeons, cans-and-wire.. and still having a stable global address? (that you could change later of course)
It's possible using overlay networks but other than that there has been no progress on that front. The routing table updates would overwhelm the system. Ipv6 does nothing to address device roaming. There is multipath TCP but I have never encountered anything using it.
Most improvements on that front has been happening on the application layer, where the app attempts to retain functionality even though the underlying network conditions are changing, to various degrees of success (mostly not that great).
