Rama: Controller Fault Tolerance in Software-Defined Networking Made Practical
[article]
2019
arXiv
pre-print
Preserved Fulltext
In Software-Defined Networking (SDN), network applications use the logically centralized network view provided by the controller to remotely orchestrate the network switches. ...
A recently proposed fault-tolerant controller platform, Ravana, solves this problem by extending fault-tolerant SDN control with mechanisms that guarantee control messages to be processed transactionally ...
INTRODUCTION Software-Defined Networking (SDN) decouples the network control plane from the data plane via a well-defined programming interface (such as OpenFlow [16] ). ...
