Service assurance is the missing link in carrier SDN.
Welcome back to a new article about SDN - this time introducing an OpenFlow controller called Faucet, developed as a RYU application by New Zeeland's Research and Education (REANNZ). In this article, I am not going to write about Faucet's architecture and features since you can read about it on its github page or here or here>. Instead, I will describe the setup used for a demo presented at the Irish Network Operators Group 11th meetup (iNOG::B).
Today’s applications are connected both to users and other applications, increasing traffic and profoundly affecting performance. Recently, there has been much discussion around the Application Performance Management (APM) category. This got me thinking about new cloud migration versus legacy application tools.

Some time back, someone challenged me to explain how ITIL impacted my workflow.
The diagram is largely inspired by my time working for a Top 5 IT Consultancy which was utterly convinced that more managers and project managers would improve the efficiency of the work performed because we could improve the process. In the end there were twelve project managers plus three manager-managers to schedule the work for just three engineers.
I pointed out that hiring another another engineer would improve work output by 33% but none of the ITIL project managers could understand this. It wasn’t about productivity, the customer, or address the need, the only focus was about hitting the deadlines, planned work hours and budgets.
ITIL is a disease. Kill it with fire.

Eyvonne Sharp wrote a great blog post describing Cisco’s love of complexity and how SD-WAN vendors proved things don’t have to be that complex.
I know Cisco (and every other vendor) loves making ever-more-complex solutions that lock you into their morass for the rest of your life (long-distance vMotion anyone?).
