abstract: |
Software synthesis is a powerful technique that can dramatically increase the productivity of programmers by automating the construction of complex programs.
One area where synthesis seems particularly promising is in computer networks.
Although Software-Defined Networking (SDN) makes it possible to build rich applications in software, programmers today are forced to deal with numerous low-level details such as encoding high-level policies using low-level hardware primitives, processing asynchronous events and dealing with unexpected failures.
This talk will present highlights from our recent works using synthesis to generate correct-by-construction network programs. In the first part of the talk, I will describe an approach for generating configuration updates that are guaranteed to preserve specified invariants. In the second part of the talk, I will present an extension that supports finer-grained updates triggered by data-plane events. In the last part of the talk, I will describe a repair technique that uses Horn clause models to repair buggy network configurations.
(Joint work with Nate Foster (Cornell University), Pavol Cerny (University of Colorado at Boulder), Jedidiah McClurg (University of Colorado at Boulder), Philipp Ruemmer (Uppsala University))
