VeloCloud & Information Brokerage

VeloCloud was the first presenter at Network Field Day 9. They are one of the new breed of SD-WAN vendors. I’m impressed by what they’re doing, and and the potential it offers for re-thinking the way we do WAN connectivity. But I think the most interesting part is the increased visibility into how networks are performing.

NFD9: Cumulus Networks

Cumulus Networks gave a great presentation at Network Field Day 9. They presented their vision of how they’re working to improve networking. But they were also clear about what they don’t do, and where they will instead enable others.

Rolling out Change

We all know that “Change is Hard.” But often we, as engineers, focus on the technical aspects of that change. How do I minimise customer impact while upgrading those routers? How can I migrate customer data safely to the new system? But we can forget about the wider implications of what we’re doing. If we do, we may struggle to get our changes implemented, or see poor take-up of new systems.

Doing Community Programs Right

You know I’m not the biggest fan of vendor clubs (or influencer marketing programs, call them what you like). But if you’re going to do it, you might as well do it right. Don’t let it just become a ‘free T-shirt club’:

CCIE Renewed - Exam 400-101

The problem with obtaining certifications is that you need to renew them. CCIE is no different - I first passed the lab in September 2012, and I was overdue for renewing it. I’m pleased to report that I have now done that, and it is now current until September 2016. Here’s some of my impressions of the 400-101 exam.

IPv6 availability in New Zealand

IPv6 has been around a fair while, and we’re constantly encouraged to learn it and use it. I agree with the sentiment, but it’s been hard for most users when few ISPs offer IPv6 for residential users. Hurricane Electric offers a great free IPv6 tunnel broker service, but that’s impractical for most people. What they need is for their ISP to offer native IPv6, by default.

NFD9 Prep: SD-WAN

Software Defined WAN, or SD-WAN, looks to be a theme of Network Field Day 9, with presenters such as CloudGenix and VeloCloud showing us their offerings. At first glance, SD-WAN sounds pretty compelling. Who wouldn’t want to slash their WAN OpEx? How do these solutions work, and do they have legs? I’m hoping to find out.

Just a quick note to say that Big Switch have updated their demo lab system. This is an entirely virtual lab environment that simulates a Big Switch network. You can try out both Big Cloud Fabric and Big Tap Monitoring Fabric.

Don't Underestimate Your Users

The “consumerisation of IT” has an interesting side-effect. Historically people mainly used computers for work. But now that many people have smartphones, tablets and laptops at home, their perception and understanding of technology has shifted. Old assumptions about training required when upgrading applications or client operating systems may no longer apply.

NFD9 Prep: NetBeez

I’m reviewing the presenters for Network Field Day 9, in particular looking at those I’m not familiar with. NetBeez is one of those making their first Tech Field Day appearance.
