Krishan Sabnani (born 1954 in New Delhi) is an Indian-American networking researcher and Research VP responsible for research on NFV and web communications at Alcatel-Lucent Bell Labs in New Jersey. He also manages internal awards such as Bell Labs Fellow. He was Vice President of Networking Research at Bell Labs from Jan. 2000 to Sept. 2013. In that role, he managed all networking research in Bell Labs, comprising nine departments in seven countries: USA, France, Germany, Ireland, India, Belgium, and South Korea.
Upon his graduation in 1981, he joined Bell Labs, Murray Hill, New Jersey as a Member of Technical Staff and was promoted to Department Head in 1993. He was named VP of Networking Research in 2000. He is also an Adjunct Professor at Columbia University and an honorary professor at IIT Delhi.
Krishan has made many seminal contributions to the Internet infrastructure design, protocol design, and wireless networks. Krishan (with T. V. Lakshman and T. Woo) made a breakthrough in Internet re-design. The main idea behind this work was to separate control functions and complex software from the forwarding portions on Internet routers. This work made it possible for forwarding technologies (e.g., different link layer and switching protocols) to evolve and be deployed independently from control protocols (e.g., routing, security). This contribution is a precursor to the current Software Defined Networking (SDN) revolution. A patent based on this work won the 2010 Edison Patent Award.2005 IEEE Eric E. Sumner Award
2005 IEEE W. Wallace McDowell Award.
The 2005, 2009 and 2010 Thomas Alva Edison Patent Award from the R&D Council of New Jersey.
