Last week we finished the last session of vSphere 6 Networking Deep Dive webinar – 6 hours of downloadable videos covering every single vSphere 6 networking topic are waiting for you.
As always, you get access to the webinar with your ipSpace.net subscription, or you can buy just this webinar, or one of the bundles that include it: Data Center track or Data Center Trilogy.
Vancouver can host all the tech shows from now on. We won't mind.
For best article visual quality, open Tutorial for creating first external SDN application for HP SDN VAN controller – Part 3/3: “Node Cutter” SDN application in perl with web interface directly at NetworkGeekStuff.
In this tutorial series, I will show you by example, how to build your first external REST API based SDN application for HP SDN VAN controller, with web interface for the user control. Target will be to learn how to use REST API, curl and perl scripting to generate some basic and useful code to view and also manipulate network traffic.
This article is part of “Tutorial for creating first external SDN application for HP SDN VAN controller” series consisting these articles:
In this Part 3/3, I will show you my first example SDN application that I have written just to demonstrate the combination of REST API interface with perl and the ability to have a web based interface for the user to this interface. Please note that this application is purely demonstrative on the REST API interface and Continue reading
For best article visual quality, open Tutorial for creating first external SDN application for HP SDN VAN controller – Part 2/3: Influencing Flows via cURL commands directly at NetworkGeekStuff.
In this tutorial series, I will show you by example, how to build your first external REST API based SDN application for HP SDN VAN controller, with web interface for the user control. Target will be to learn how to use REST API, curl and perl scripting to generate some basic and useful code to view and also manipulate network traffic.
This article is part of “Tutorial for creating first external SDN application for HP SDN VAN controller” series consisting these articles:
In this Part 2/3, we will discuss how to create a few cURL commands in linux environment, authenticate to the controller REST API interface and generate flows to modify the forwarding path overriding the controller decisions.
Lets start with the basics, in linux console exists Continue reading
Python is one of the easiest programming languages to learn, because of it’s inherent flexibility. (This can be a good thing as well as a bad thing.)
One example of Python’s flexibility is the double parentheses. Take the following snippet for example:
print funcwrapper(3)(2)
Even an inexperienced programmer should be able to make sense of most of this. Reading from left to right, it looks like we want to print the output of a function, and we’re passing an integer - 3 - to that function. However, the second pair of parentheses doesn’t quite make sense.
This notation is different from what we would do if we wanted to pass two arguments to a function; in that case, we’d put them all inside a single pair of parentheses and separate them via commas:
print funcwrapper(3, 2)
So what does the first example using two pairs of parentheses accomplish?
The use of a double parentheses is actually an indicator of one of Python’s coolest features - and that is that functions are themselves, objects! What does this mean?
Let’s work our way up to the snippet above by first defining a very simple function - something that takes an integer Continue reading

Tsk, tsk, Cisco -- a possible Nutanix acquisition and illegal deals with the Russians? Find out more in this week's roundup!
Vijay Sagar and Aaron Edwards of CloudGenix discuss the software defined WAN with the Packet Pushers. We've heard from CloudGenix before on Priority Queue Show 49. If you missed that show, you might want to give it a listen first to get the most out of this podcast. On this show, we go a bit deeper into CloudGenix -- what it does, how it does it, and how you'd integrate it into your network.
