7 years ago, IIT Bombay entered into an agreement with state-owned PSU ECIL, to transfer technology for building commercial switch routers. This transfer of technology was the largest in the history of IITB. This talk gives a 360-degree view of the design, development, tech transfer, deployment, success and shortcomings of the router story. We begin with the initial development of the routers – a typical telecom provider architecture and our proposed Omnipresent Ethernet concept. We explain the concept from a layman perspective and describe as to how it fits into the larger telecom network. We then discuss the development of the indigenous routers (called Carrier Ethernet Switch Routers).
The first prototype led to the development of three routers a baby switch, a baba edge router and a grandpa core router. We shall discuss the architecture, the code and the management system of this family of CESRs. Thereafter I shall explain how the CESRs fit into the Indian telecom landscape through the initial deployment in telco networks. Subsequently I will describe recent successes through user testimonials. I will also talk about the shortcomings of our story. I shall conclude the talk with a glimpse of our current efforts for the Min. of Defense, a Terabit SDN Router that was recently built and launched. Here, I will highlight the proposed Bitstream contribution – as a more refined version of the original architecture, where even complex networking functions such as firewalls, load balancers are implemented within the router premise.
Ashwin Gumaste is a Professor in the Dept. of CSE at IIT Bombay in Mumbai where he has been employed since 2005. He was previously the Institute Chair Associate Professor (2012-2015) and the JR Isaac air Assistant Professor (2008-11) at IITB. Ashwin has held positions with Fujitsu Laboratories (USA) (2001-2005) and has also worked with Cisco Systems (2000-2001). He was a consultant to Nokia Siemens Networks focusing on the emerging NGPON2. He has also held short-term positions with MIT (2008-2009) Lawrence Berkeley National Labs (2015) and Iowa State University (2009). His work on light-trails has been widely referred, deployed and recognized by both industry and academia. His recent work on Omnipresent Ethernet has been adopted by tier-1 service providers and also resulted in the largest ever acquisition between any IIT and the industry. This has led to a family of transport products under the premise of Carrier Ethernet Switch Routers. Recently Ashwin’s team has built a Terabit capable SDN Whitebox. Ashwin has 25 granted US patents and has published about 175 papers in referred conferences and journals. He has authored three books in broadband networks. For development contributions he was awarded the S. S. Bhatnagar Award 2018, DST Swaranajayanti Fellowship in 2013, Dept. of Atomic Energy’s-SRC Outstanding Research Investigator Award in 2010, the DOS’s Vikram Sarabhai research award in 2012. He was also awarded the IBM Faculty award in 2012, the National Academy of Sciences in India, NASI-Reliance Industries Platinum Jubilee award 2016, the Indian National Academy of Engineering’s (INAE) Young Engineer Award (2010) and INAE Fellow 2018.
