I make no secret of my love for Seth Godin and his amazing insight into the world. Besides being a marketing genius, he’s like Ockham’s Razor in getting to the essence of a problem. Take today’s posting, which really resonated with me, because it seems to reflect my own frustration with a common problem in […]

I wanted to take just a moment and share a video that one of my twitter friends shared with me. This video is of the final stage of the interview process and outlines the negotiation required to come to a mutually agreeable compensation level. Of key importance, it highlights several items that should be understood […]

Scale has been an active (and often contentious) topic in the discourse around SDN (and by SDN we refer to the traditional definition) long before the term was coined. Criticism of the work that lead to SDN argued that changing the model of the control plane from anything but full distribution would lead to scalability challenges. Later arguments reasoned that SDN results in *more* scalable network designs because there is no longer the need to flood the entire network state in order to create a global view at each switch. Finally, there is the common concern that calls into question the scalability of using traditional SDN (a la OpenFlow) to control physical switches due to forwarding table limits.
However, while there has been a lot of talk, there have been relatively few real-world examples to back up the rhetoric. Most arguments appeal to reason, argue (sometimes convincingly) from first principles, or point to related but ultimately different systems.
The goal of this post is to add to the discourse by presenting some scaling data, taken over a two-year period, from a production network virtualization Continue reading
[This content was originally published on thenetworksherpa.com] Have you ever sat at your desk repeating the same task again and again, getting that groundhog day feeling. Arrrghhh, this is so inefficient someone should automate this. I could even do it myself with five days of focussed work. Sadly, you don’t have five days and the […]

As an introvert, I don’t like ice breakers or team building exercises at team meetings. Building the team camaraderie is done slowly over time with peers you work with. Daily interactions during work help build that as engineers learn to trust each other. What about for a team that does not interact with each other […]

Companies are Systems for Making Money We’ve all heard corporate leadership speak about ‘human resources’ and that ‘people are our most important asset’. This is true but the words ‘resource’ and ‘asset’ were carefully chosen. A resource is something to be mined for value. Please don’t be fooled into thinking that your company cares […]

Why does it happen with every technology cycle? First, there’s a period of great innovation, followed by the introduction of new terms and categories, which is always followed by a frenzy of differentiation-by-acronym. Everyone gets caught up in talking to each other and one-upping each other, instead of remembering why there was innovation in the first place. I call it “the yearbook effect,” and the networking industry and those who work in it, watch it and write about it are fully entrenched in it right now.
Think about it. SDN, NFV, OpenFlow, controllers, consortiums to build controllers, control plane separation, overlays, blah blah blah.
The industry has gotten so wrapped up in talking about definitions of SDN, the various technologies and how they get implemented, we actually may help delay adoption. We are supposed to be trying to help customers, but we are focusing on the wrong things and it’s confusing them.
I may get kicked out of the SDN fan club for saying this, but I’ve come to the conclusion after speaking to dozens of customers and participating in various industry discussions, any delay in widespread adoption of SDN is our own fault.
People are rarely, if ever, talking Continue reading
The Packet Pushers are joined by Brent Salisbury of networkstatic.net for a chat with some of the top brass on the OpenDaylight project’s Technical Steering Committee, Dave Meyer and Inder Gopal. “What’s OpenDaylight?” you ask. Why, it’s a consortium of vendors working together under the Linux Foundation umbrella to make an open source reference framework […]

Here I come with the solution for quiz-12, that I consider to be one of the most difficult quizes published on this blog, until now. Forwarding Address (FA) is not quite a common nor easy to understand topic. Read to find out more.
How did I not know this until just now? A really nice way to use wildcards in prefix lists that reference other parts of Junos to save you time. And nicely written up too – here.
At work, we’ve been getting ready to deploy a few different cluster technologies. One is a set of KVM hosts to offer VMaaS functionality to end users. Another is a CEPH cluster (http://ceph.com/) which is smart distributed storage. The third is a Hadoop cluster. Each of these initiatives popped up around the same time and […]

Your job hunt traditionally starts with websites like monster.com or dice.com. However, some surveys suggest that between 70 to 80 percent of jobs are found through personal contacts and relationships. So why not spend your efforts building your relationships instead of surfing jobs sites? I can sense some of you getting uncomfortable already. Dont worry, […]
