Some impact of my work beyond research papers

  • CricInfo
    In the past, I was a founding team member of the world's largest sports portal, CricInfo. I played the role of CTO in the formative years. We wrote our own webserver (pre-apache), had our own little CDN (pre-Akamai) and have been credited as inventing live blogging. Here is an article that I wrote as part of the 20th anniversary celebrations about a night that changed CricInfo.
  • Bufferbloat
    My PhD thesis developed the first stochastic differential equation (fluid) model of TCP that led to formal control theoretic analysis of congestion control mechanisms on the Internet. We ourselves took the model and proposed the PI controller as a way to better control TCP and manage latencies. Many years later, an engineering team at Cisco developed the PIE (PI Enhanced) controller based on our PI controller that is being used to solve the problem of "bufferbloat" (excessive delays on the Internet because of larger than needed buffers). The PIE controller has become a part of the DOCSIS 3.1 standard and will soon be deployed on all cable modems around the world.
  • Infinio
    In Summer of 2011, along with my colleague Dan Rubenstein and PhD student Joshua Reich, I founded another company Infinio (nee Silver Lining) in the area of datacenter storage and networking. Soon Arun Agarwal joined the founding group and after we recruited a fantastic team, I have transitioned to the role of Chief Scientist. The company is backed by major VC firms like Bessemer Venture Partners, Highland Capital Partners and Lightspeed Venture Partners, has raised over 24 Million dollars and employs over 60 people with offices in Massachusetts and New Hampshire.
  • Network Neutrality
    While I have written a lot of papers analyzing the economic ecosystem of the Internet, one particular aspect we have been emphasizing is the importance of competition. In 2011, together with my former student Richard Ma, we wrote a paper proposing a Public Option ISP, via a mechanism like Municipal Broadband to address the issue of Network Neutrality. The idea, also proposed by people from the legal/regulatory side like Susan Crawford, has gained a lot of momemtum with even President Obama getting behind it.
