Transiently Secure Network Updates
Arne Ludwig, Szymon Dudycz, Matthias Rost, Stefan Schmid · 2016
Computer networks have become a critical infrastructure. Especially in shared environments such as datacenters it is important that a correct, consistent and secure network operation is guaranteed at any time, even during routing policy updates. In particular, at no point in time should it be possible for packets to bypass security critical waypoints~(such as a firewall or IDS) or to be forwarded along loops.
