Fast failure detection and recovery mechanism for dynamic networks using software-defined networking
Rufaida Ahmed, Ethar Alfaki, Mustafa Nawari · 2016
Software-defined networking is a modern network paradigm that eases networks management, and enables dynamic networks configuration by separating the control plane from the data plane. But the struggle of failure detection and recovery in a timely manner is still intractable. In this paper we introduce a failover scheme using per-link Bidirectional forwarding detection sessions and preconfigured primary and backup path computed using a controller (domain specific language) called Kinetic. The proposed design and implementation reduced the recovery time in a relatively simple manner to less than 50 ms.
