Open vSwitch 2014 Fall Conference: Traffic Visibility and Control with sFlow

Open vSwitch 2014 Fall Conference: Traffic Visibility and Control with sFlow

presented by: Peter Phaal, InMon

sFlow instrumentation has been included in Open vSwitch since version 0.99.1 (released 25 Jan 2010). This talk will introduce the sFlow architecture and discuss how it differs from NetFlow/IPFIX, particularly in regards to delivering real-time flow analytics to an SDN controller. The talk will demonstrate that sFlow measurements from Open vSwitch are identical to sFlow measurements made in hardware on bare metal switches, providing unified, end-to-end, measurement across physical and virtual networks. Finally, Open vSwitch / Mininet will be used to demonstrate Elephant flow detection and marking using a combination of sFlow and OpenFlow.
