Tech Notes: Juniper QFabric – A Perspective on Scaling Up
Juniper QFabric is a new approach to Ethernet Switch Fabrics. When it was announced last year,it was noted that the underlying physical design is a completely different approach to building Switch Fabrics. Here I’m taking a loosely research based approach to understand how Juniper QFabric is different from all other approaches to the problem, and also a look at some of the challenges ahead.
Using Underscores, Hyphens or CamelCase in Naming Standards
I’ve been considering a small but vital problem in naming conventions in Networking. Namely, the use of underscores and hyphens in object names and devices. It’s a hot topic for argument when the time comes for corporate standards (and when Network Engineers have beverages in a public house). Now, I figure that there are three possible grammar options for making names – hyphens, underscore and CamelCase.

Going to RSA? Located in Silicon Valley? Here’s a rare opportunity to learn about SDN from the people who introduced Greg Ferro to OpenFlow. Get tips, tricks and pitfalls about running a live production multi-vendor SDN network. Feb 28th/29th during RSA at the St. Regis Hotel.
Defining Flow Forwarding Instead of Switch or Routing
Wherein I make the case OpenFlow like technologies are neither switching or routing. It’s Flow Forwarding, or just Forwarding.
Predicting What Will Not Be Big in 2012
I’ve been working on making some predictions about 2012 and networking. I like to do this in the year of 2012 (not 2011 like everyone else) and I like to go further than anyone else and predict what WILL NOT be big in 2012.

Tech Review: NETCONF and YANG
Over the last few months I’ve been looking at Network Management options that are not OpenFlow or SNMP based. This led to NETCONF & YANG and these are my working notes from some time spent reading and researching.

Will SDN/OpenFlow Be Used in the Enterprise ?
Following the OpenFlow/SDN webinar last week, Brad sent me this question:
What does your crystal ball tell you regarding industry acceptance? I can see the Google’s of the world needing this—but what about the average enterprise?
Here is my best effort at answering:

Is OpenFlow Open ? I Ask – Compared to What ?
I’ve always wondered whether the Open Networking Foundation is the correct caretaker of the standards process for Software Defined Networking. Recently, we’ve seen some questioning of the direction of those standards on OpenFlow, and, now that we are beginning to understand the concepts of controllers, Software Defined Networking these are good questions to ask. it shows [...]
