Open vSwitch 2015 Fall Conference

Open vSwitch is an open source software virtual switch that is popular in cloud environments such as OpenStack. Open vSwitch is a standard Linux component that forms the basis of a number of commercial and open source solutions for network virtualization, tenant isolation, and network function virtualization (NFV) - implementing distributed virtual firewalls and routers.

The recent Open vSwitch 2015 Fall Conference agenda included a wide variety speakers addressing a range of topics, including: Open Network Virtualization (OVN), containers, service chaining,  and network function virtualization (NFV).

The video above is a recording of the following sFlow related talk from the conference:

New OVS instrumentation features aimed at real-time monitoring of virtual networks (Peter Phaal, InMon)
The talk will describe the recently added packet-sampling mechanism that returns the full list of OVS actions from the kernel. A demonstration will show how the OVS sFlow agent uses this mechanism to provide real-time tunnel visibility. The motivation for this visibility will be discussed, using examples such as end-to-end troubleshooting across physical and virtual networks, and tuning network packet paths by influencing workload placement in a VM/Container environment.

This talk is a follow up to an Open vSwitch 2014 Fall Conference talk on the role of monitoring in building feedback control systems.

Slides and videos for all the conference talks are available on the Open vSwitch web site.
