Query: OSDF: A Framework For Software Defined Network Programming   Using SDN to configure and control a multi-site network involves writing code
that handles low-level details. We describe preliminary work on a framework
that takes a network description and set of policies as input, and handles all
the details of deriving routes and installing flow rules in switches. The paper
describes key software components and reports preliminary results.
