Yogesh Mundada gave a talk at the Click Symposium in Belgium last week on his new OpenFlow Click Element, which he developed with Rob Sherwood at Deutche Telekom Labs.
The OpenFlow Click element is a module for the Click modular router that can be controlled via a standard OpenFlow controller. The element essentially turns a Click router into a software switch with flow table entries. One of the most powerful aspects of this paradigm is that it allows hybrid packet and flow processing, as part of a paradigm we call Flowlets.
