Biography

At Bell Labs, I lead the Access Control department in the End to End Network Service Automation lab. My research focuses on providing generic/programmable network functions and its algorithms and protocols to improve content delivery, service automation  and facilitating network application development. I’m interested in transport protocol - network, application - network and cross-layer network interactions.

Project contributions:

MIA: Multi Gigabit Innovations in Access
5GBB: Low latency transport protocols and AQMs
SHIFT-TV: Multi-Screen, -Place and Time-Shifted Digital Television; Transport protocol for adaptive live and on demand streaming
FP7 RITE: Low latency transport protocols and AQMs
FP7 OCEAN: Caching strategies for multimedia delivery
IWT PHANTER: HAS caching with multicast feeds for live streams; Transport protocol for streaming
FP7 ECODE: Machine learning for transport layer accountability
CELTIC RUBENS: Scalable application agnostic transport protocol for multimedia delivery; PCN for VBR video delivery
