How much are you worth per hour

[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 […]

Teamwork in a Disconnected Environment

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 […]

Your Company Doesn’t Care About You

  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 […]

SDN: Stop Differentiating by Names

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

Outgoing Interface Determination

I received a comment on an old post regarding the identification of outgoing interface for learned routes through BGP. In fact, it’s not the first time I’ve had a discussion in the comment section regarding the interaction between the control plane and the forwarding plane. So, let’s work backwards from the point where our packet leaves some interface on a router, which would be considered purely an act of the forwarding plane.

Making sense of Broadband networks – Part 1

Broadband is a hot topic in the telecommunications industry nowadays; it is becoming the bread and butter for so many service providers and mobile carriers with the big growth and penetration rates in these technologies in the recent years.  ( Check this report about the EOCD countries). Although it is that important, broadband topics probably [...] No related posts. Related posts brought to you by Yet Another Related Posts Plugin.

Network Design Challenge – Small Little Clouds

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 […]

Build a Career with Relationships

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, […]

[Virtual Routing] Part 4 – The Use Case

Moving along in my “Virtual Routing” series, I’d like to switch gears and talk a little more “big picture”. In the previous posts, we’ve discussed a few different things: Part 1 - A first look at the CSR 1000v from Cisco Part 2 - An examinations of using FHRPs in a virtual environment Part 3 - A comparison of virtual routing redundancy options Seeing as these were all pretty technical configuration-oriented posts, I wanted to take a step back and think about some of the reasons why one would want to perform routing in a virtual environment.

Review: ScienceLogic – One Network Management Tool To Rule Them All?

ScienceLogic has been getting the right kind of press recently – e.g. they were a winner of Best of Interop 2013 – Management & Monitoring, and Infoworld had some rather nice things to say. They’ve got some high-profile customers too, such as Fasthosts and Equinix. But what exactly is their product all about, and is it any […]
