Paper on using MirageOS for better SDN infrastructure with OpenFlow. Working with Charalampos Rotsos, Richard Mortier, and others, we demonstrated how applications could express their own forwarding logic using OpenFlow to achieve optimal performance in cloud environments. We built modular OpenFlow controllers and switches as Mirage libraries that link directly into applications, providing a safe yet extensible framework for programming network control. The work showed how the unikernel approach could address the lack of traffic isolation in virtualized datacenters while giving applications direct control over their networking.
