Dr. Krishnamurthy has been measuring various aspects of the Web and the Internet as part of improving the user's Web experience while reducing load on the network. A global infrastructure has been built around this effort that has led to gathering of data at various levels of the protocol stack. Dr. Krishnamurthy presented a quick overview of various research projects that he has been involved in over the last four years. The remainder of the talk focused on some recent examination of netflow data to characterize DNS traffic, via passive and active measurements as well as a graph-based analysis.


Balachander Krishnamurthy has published in various conferences including SIGCOMM, Infocom, WWW, Usenix, USITS, etc. He has co-authored a Proposed Standard on adding a delta mechanism to HTTP/1.1, has co-written and edited a book on UNIX, and was series editor for 8 volumes in the "Trends in Software" series of books. Dr. Krishnamurthy has published over 50 technical papers and has lectured in nearly thirty countries. He holds several patents in the Web arena.
