During one of my SDN workshops one of the attendees working for a mid-sized European ISP asked me this question:
Our management tells us we should build our network like Google does, including building our own switches. Where should we start?
The only answer I could give him was “You don’t have a chance.”

VMware, Cisco, and Verizon make the top 3.
Careers take a funny turn a lot of times. Opportunities come up that you weren’t expecting and the timing is never as perfect as you want it to be. At least, that is how it has always been with me. I’ve learned though, that sometimes the best thing for you is to charge full speed ahead through the door, roll the dice, and take your chances. That is where I find myself right now. Having accepted an offer from Aerohive Networks to serve in a pre-sales engineering role in my local area, I am leaving behind a job and a company that I have enjoyed tremendously. Yes, there were times when I had to be talked off the ledge and keep on going. I think that comes with most jobs though. Overall, it has been a very rewarding almost 5 years working for a value added reseller(VAR) and I will miss it greatly.
In the span of a few months, I had to decide to give up the following:
1. Multi-vendor implementations and support.
2. Studying for the CCIE Wireless lab exam with 1 failed lab attempt already under my belt.
3. Involvement with other vendors courtesy of social media(blogging, Continue reading
Netronome Agilio is a niche play for customers with specific compute requirements centered around OVS and, soon, Juniper Contrail. The majority of data center owners are likely to find that they just don't have the problems that Netronome is solving, but those that do will be pleased that Netronome exists.

Cisco estimates 50 billion devices and objects will be connected to the Internet by 2020. And that estimate may be low. If consumers count every device that draws power in their home – lamps, light bulbs, kitchen gadgets – and then factor in objects at work, there may be many more billions of connected devices by then.
But the problem is, many traditional networks are still manual, static and complex, which isn’t ideal for IoT. To realize the promise of a hyper-connected future, three shifts must take place.

In 2001, a bunch of people got together and wrote a manifesto on Agile software. There were two main factors that made the output suspect. First, the fact that they even called it a manifesto. Second, the manifesto had nothing to do with software. It talked about values.
For those in need of a refresher, here’s the “Manifesto for Agile Software Development:”
We are uncovering better ways of developing software by doing it and helping others do it. Through this work we have come to value:
-- Individuals and interactions over processes and tools
-- Working software over comprehensive documentation
-- Customer collaboration over contract negotiation
-- Responding to change over following a plan --
That is, while there is value in the items on the right, we value the items on the left more.
Somewhere along the line, we started doing daily standups, two-week sprints, maybe a little pair programming here and there. Since then our software output and productivity have sky-rocketed. Remember when we used to have an end-of-project company bug hunt? How about the integration Continue reading

Introduction
BGP Confederations are one of two tools a network designer has to work around the full mesh requirement of iBGP. BGP confederations are defined in RFC 5065 which obsoletes RFC 3065. This is how the RFC defines BGP confederations:
This document describes an extension to BGP that may be used
to create a confederation of autonomous systems that is
represented as a single autonomous system to BGP peers
external to the confederation, thereby removing the “full mesh”
requirement. The intention of this extension is to aid in
policy administration and reduce the management complexity
of maintaining a large autonomous system.
The other option to work around the full mesh requirement is of course route reflection.
BGP Confederation Operation and Use Case
BGP confederations work by having several sub AS or member AS that are used internally to divide the BGP domain. From the outside they all look like they are the same AS though. By breaking up the BGP domain, there will be less iBGP peerings which makes the full mesh requirements easier to handle. Do note though that it’s entirely possible to use route reflection within a member AS to combine the two technologies.
BGP confederations made a Continue reading
