Consistent and Secure Network Updates Made Practical
James Lembke, Srivatsan Ravi, Pierre-Louis Roman, Patrick Th. Eugster · 2020
Software-defined wide area networking (SD-WAN) enables dynamic network policy control over a large distributed network via network updates. To be practical, network updates must be both consistent, i.e., free of transient errors caused by updates to multiple switches, and secure, i.e., free of errors caused by faulty or malicious members of the control plane. Besides, these properties must incur minimal overhead to controllers and switches.
