Carl Klatsky, Comcast

Carl Klatsky currently works for Comcast as a Senior Principal Engineer. He has led critical technology changes to Comcast's network, such as transitioning Comcast's Voice CPE from using the NCS protocol to the SIP protocol, developing & deploying DOCSIS 3.0 CPE, transitioning Comcast's Voice CPE from IPv4 to IPv6, and his most recent work in evaluating bufferbloat mitigigation techniques on DOCSIS CPE. Carl received his M.S. in Software Engineering from Monmouth University and his B.E. in Electrical Engineering from Stevens Institute of Technology.
Abstract: The Cable Industry has been investigating techniques for mitigating the Bufferbloat (www.bufferbloat.net) condition seen on the Internet. CableLabs has selected an Active Queue Management (AQM) technique called PIE (Proportional Integral controller Enhanced) as part of the DOCSIS 3.1 standards. In advance of AQM capable DOCSIS 3.1 equipment becoming available, Comcast has conducted a field trial using a static queue management approach. The goal of the trial was to measure the impact of a bufferbloat mitigation technique implemented on Comcast leased DOCSIS 3.0 modems. This presentation shares the trial methodology, results obtained, and success & challenges encountered.
