Cisco's David Ward makes surprise appearance at NFV World Congress.
NETCONF is an industry standard (IETF) network management protocol. It’s actually been around for quite awhile and supported by numerous vendors. While NETCONF is not always compatible across network switch platforms, it’s the closest thing I can see that could be a unified multi-vendor API. Of course, there are also vendor extensions for those device-specific features too.
I’m not going to get too much into what NETCONF is because Matt Oswalt has already done that. Check out his post if you haven’t already done so. There are also plenty of other good resources on NETCONF out there.
What I am going to focus on in this post is using Python to interact with NETCONF-enabled network switches.
Let’s get to it.
First, you’ll want to install the ncclient. It is pretty much the de facto Python library to use when you need a NETCONF client to communicate with a NETCONF server, i.e. a network device.
sudo pip install ncclient
This will also install a few other required dependencies such as paramiko and lxml along with the client itself.
The next thing you are going to need is at least one switch (or device) that supports NETCONF. In this post, I’m Continue reading
A Layer 0-7 SDN controller is among the aspects of AT&T's SDN plan, built upon DevOps-like trial and error.
Q3 comes in as promised, which isn't good news.
With the recent release of Ubuntu 15.04, aka “Vivid Vervet”, the Ubuntu community has also unveiled an early release of LXD (pronounced “lex-dee”), a new project aimed at revitalizing the use of LXC and LXC-based containers in the face of application container efforts such as Docker and rkt. In this post, I’ll provide a quick introduction to LXD.
To make it easier to follow along with some of the examples of using LXD, I’ve created an lxd
directory in my GitHub “learning-tools” repository. In that directory, you’ll find a Vagrantfile
that will allow you to quickly and easily spin up one or more VMs with LXD.
LXD works in conjunction with LXC and is not designed to replace or supplant LXC. Instead, it’s intended to make LXC-based containers easier to use through the addition of a back-end daemon supporting a REST API and a straightforward CLI client that works with both the local daemon and remote daemons via the REST API. You can get more information about LXD via the LXD web site. Also, if you’re unfamiliar with LXC, check out this brief introduction to LXC. Once you’ve read that, you can browse some Continue reading

The topic of "do you trust RRM" is often discussed. The most typical answer is: "Yes, if I understand it." I know I've personally spent numerous hours blaming RRM for a questionable Dynamic Channel Assignment (DCA), and I'm usually wrong.
For the purpose of this post, RRM = Radio Resource Management; be it ARM (Aruba), RRM (Cisco), ACSP (Aerohive), SmartRF (Extreme) etc. etc.
This post isn't about the topic of "trust", or if to use RRM. Here's a good post by @wirednot on that topic. (Read the comments!)
This is more about:
The system in question is an Aruba Instant AP (Instant OS version 6.3.1.8-4.0.0.9).
Data Gathering
Typically, I use Pexpect for screen-scraping CLI output but Aruba has written a handy utility to do this for you. It's called Air Recorder, and is multi-platform (Java.) Will run on Continue reading

Wikipedia defines workflow as “an orchestrated and repeatable pattern of business activity enabled by the systematic organization of resources into processes” - processesthat make things or just generally get work done. Manufacturers can thank workflows for revolutionizing the production of everything from cars to chocolate bars. Management wonks have built careers on applying workflow theories like Lean and TQM to their business processes.

This vendor-written tech primer has been edited by Network World to eliminate product promotion, but readers should note it will likely favor the submitter’s approach.
Many companies face the dilemma of how to get the most out of legacy IT equipment and applications while taking advantage of the latest cloud advances to keep their company competitive and nimble.
A hybrid approach to IT infrastructure enables internal IT groups to support legacy systems with the flexibility to optimize service delivery and performance thru third-party providers. Reconciling resources leads to improved business agility, more rapid delivery of services, exposure to innovative technologies, and increased network availability and business uptime, without having to make the budget case for CAPEX investment.
