Efficiency vs Effectiveness

I’ve been wondering about how we’re approaching networking change. We know we need to make things better. Are we changing the ‘right’ things? I’ve got a feeling that we’re not, but I suspect that we’re too constrained by higher-order systems. Simon Wardley wrote a great post on Efficiency vs Effectiveness. He gave a slightly contrived […]

Brocade PyNOS Python Libraries

PyNOS v1.1 has been published. This is a python library that simplifies automating Brocade VDX systems. It is built on top of ncclient, and uses NETCONF to communicate with the VDX systems. Using the libraries is much simpler than writing your own NETCONF calls. What can I do with it? Use Python to script configuration or […]

Networking Pioneers, Settlers and Town Planners

Can we broadly separate Networking into Pioneers, Settlers, and Town Planners? I’ve been thinking about how to apply Simon Wardley’s PST model to networking. This leads to thinking about how we can encourage networking evolution. The model needs a lot of fleshing out, but I’m interested in what others think. Pioneers, Settlers and Town Planners […]

If you’ve visited the Brocade website recently, you’ve probably seen the “Free NFV Certification” banner. I signed up for this several months ago, but had put off completing the course. I had a little downtime recently prior to starting work at Brocade, so I completed this course & exam. Here’s my impressions. What’s the Course/Exam About? […]

You can’t put the future on hold

Greg Ferro recently participated in an “Ask Me Anything” thread on Reddit. In that thread, user “1DumbQuestion” made this comment: Last, never finished my CCIE because of what I perceive will happen with SDN in the next coming years. I’ve seen similar comments from others over the last couple of years. This concerns me because […]

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. I […]

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. Linux on a switch? Seems natural to me Many network engineers started out running cables, and […]

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. […]
