Puneet Sharma

Puneet Sharma is Distinguished Technologist from the Hewlett Packard Laboratories, Palo Alto, CA[1] where he heads Networked Systems group. He started his research career as Research Scientist at HP Labs in September 1998.

Sharma was born in Delhi, India. He graduated with a B.Tech. in Computer Science and Engineering from Indian Institute of Technology, Delhi in 1993. He earned his PhD in Computer Science from the University of Southern California.During his doctoral studies he contributed to standardization of Protocol Independent Multicast.[2]

His Ph.D. dissertation titled "Scaling control traffic in network protocols"[3] hypothesizes that unregulated growth of network control traffic such as routing, signalling and end-to-end protocol can jeopardize the primary function of the networks to carry data traffic. The dissertation presents designs for regulating network control traffic along three scaling dimensions: (1) frequency, (2) distribution scope, and (3) information aggregation. Several network protocols use soft state paradigm for state management. These protocols use periodic refresh messages to keep network state alive while adapting to changing network conditions. However, the scalability of protocols that use the soft-state approach is a concern. He co-invented Scalable Timers[4] approach for soft state protocols where timer-values are adapted dynamically in accordance with the volume of control traffic and the available bandwidth on network link.

He was named Fellow of the Institute of Electrical and Electronics Engineers (IEEE) in 2014[5] for contributions to the design of scalable networking, software defined networks and energy efficiency in data centers. In 2011, Sharma was recognized as Distinguished Member of the Association for Computing Machinery (ACM) for contributions to computing research.[6]

His work on Mobile Collaborative Communities has been featured in the New Scientist Magazine.[7]

In November 2015, Sharma's work on performance characterization of Virtual Network Functions (VNF) received Best Paper Award at 1st IEEE NFV-SDN conference.
