Abstract
The architectural elements of the Internet that led to its great success are now, paradoxically, the same elements that are the source of many of its severest problems. For example, the use of autonomous systems to geographically decouple topology and governance allowed rapid growth and scaling, but has made the network unmanageable, and unable to provide end-to-end quality of service. In this lecture, the speaker will examine this and other key design elements of Internet architecture, show how they have contributed to its success, and how they now severely constrain it. He will then use this framework to identify some key challenges that we need to address in the next decades of Internet research.
About the speaker
Prof Srinivasan Keshav received his BTech in Computer Science and Engineering from IIT Delhi in 1986 and PhD in Computer Science from the University of California at Berkeley in 1991. He was subsequently a researcher at AT&T Bell Laboratories and, from 1996 to 1999, an Associate Professor at Cornell University. In 1999, he left academia to co-found Ensim Corporation and GreenBorder Technologies Inc. He was an Associate Professor at the University of Waterloo from 2003 to 2008 and has been a Professor since, holding a Canada Research Chair (2004-14) and the Cisco Chair in Smart Grid (since 2012).
Prof Keshav has published two graduate textbooks on computer networking, namely An Engineering Approach to Computer Networking in 1997 and Mathematical Foundations of Computer Networking in 2015. He is also the co-author of Integration of Renewable Generation and Elastic Loads into Distribution Grids in 2016. Besides, he is currently the steering committee member of ACM SIGMETRICS PACM Series.
Prof Keshav is an awardee of the Director's Gold Medal from IIT Delhi in 1986, the Sakrison Prize from UC Berkeley in 1991, two Test of Time awards from ACM SIGCOMM in 2006, and Best Paper awards at both ACM SIGCOMM 1991 and ACM MOBICOM 2009. He is the co-director of the Information Systems and Science for Energy Laboratory, an Alfred P. Sloan Fellow, an ACM Fellow, and currently Chair of ACM SIGCOMM.
