Performance Aware SDN by Peter Phaal, Inventor of sFlow, Co-Founder InMon

For this event we will be hosting Peter Phaal who is the original inventor and co-author of the sFlow standard. He will be doing Tech Talk on Performance Aware Software Defined Networking and also conducting hands-on lab using sFlow.

About Peter Phaal

Peter is the original inventor and co-author of the sFlow standard. He is also the President and Founder of InMon Corp., a leading provider of performance analysis software based on sFlow. Before InMon, Peter worked at Hewlett-Packard Laboratories where he created Hewlett-Packard’s Extended RMON technology. His book, LAN Traffic Management, describes the techniques of monitoring and managing traffic on local area networks. Peter has over 20 years experience in the field of network performance monitoring.

Introduction to sFlow standard, sFlow basics, how to configure sFlow on the Open vSwitch. Relationship between sFlow and OpenFlow and integration of sFlow performance analytics in SDN stack.Discussion of use cases, including: load balancing, DDoS mitigation and packet brokers.

Hands on lab using sFlow-RT and sFlow data captured from physical and virtual switches. For the lab we will be following examples from the following blog: To participate in the lab, please install the following software on your laptop: sFlow-RT (, Java 1.6+, cURL, and Python (with Requests library, To test your setup, try running examples in sFlow-RT extras/ directory.

OpenFlow/SDN hands-on tutorial
