Study on configuration change practices

The key distinction of our research is that it focuses on networks running
traditional distributed routing protocols. In an SDN you have significant
flexibility over how you decide to route/filter traffic, whereas in a
traditional network you have to satisfy intents using the capabilities of
existing routing protocols. Obviously SDN's flexibility is what makes it
attractive, but there is also (significant) overhead to (partially) switch
to this architectures. We recognize that traditional routing protocols
still far outstrip SDN in terms of deployment, so there is a real need for
intent-driven frameworks that work with traditional routing protocols.
We are not alone in building intent-driven frameworks for traditional
routing protocols. Other research (e.g., https://netcomplete.ethz.ch and
https://github.com/rabeckett/propane) has also taken an intent-driven
approach for traditional routing protocols. What differentiates our work is
a focus on _updating_ existing configurations rather than generating new
configurations from scratch each time the intents change.
P.S. Thanks for taking the survey!
