P4: high-level language for programming protocol-independent packet processors
In collaboration with Barefoot Networks, Google, Intel, Microsoft, and Princeton University, we proposed P4 as a high-level language for programming protocol-independent packet processors. P4 works in conjunction with SDN control protocols like OpenFlow.

SDN Version Control
We have built a distributed controller that logs flow table changes. Using a Lamport clock to reason about causality, we preserve histories of the network configurations and the applications and events that caused changes to the network.

Network Virtualization
In collaboration with Open Networking Laboratory (ON.Lab) we are developing OpenVirteX, a network virtualization platform that enables operators to create and manage virtual Software Defined Networks (vSDNs).

SDN Based Private Cloud
Two disruptive technologies that the Web infrastructure builds on are multi-tenancy virtualized clusters and, more recently, Software Defined Networks (SDN). Multi-tenancy virtualized clusters enable scale-out designs with very flexible resource use and the best cost performance.
