I led the congestion control and some host performance debugging efforts for these networking stacks.
I used the programmable switching hardware in non-traditional networking applications such as Deep Insight, In-network DDoS Detection, Matching string queries, Packet subscription and Machine learning acceleration.
Such systems allow operators to define high level intents and leverage efficient algorithms at the controller, switches and end-hosts. These algorithms can quickly fine tune the switches and end-hosts to keep high accuracy, drill down fast into issues, and leverage device optimizations and network knowledge to scale. I developed four systems: vCRIB (NSDI'13), DREAM (SIGCOMM'14), SCREAM (CoNEXT'15) and Trumpet (SIGCOMM'16).
