I am going to deviate a little bit from my normal career advice here and talk about something a bit more personal for me. I have told this story to colleagues at times over the past several years, and I am always a little surprised that everyone appears to feel the same way. But we […]

Company ABC is in process of configuring BGP Confederations between its sites. During a small transition period, there will be no BGP between R3 and R2, but instead only static routing. Have a look at the quiz and try answering the question !
There are many different personality traits found in individuals in our industry. One trait that I’ve found dominant in technical roles is that of introversion. This trait is one that often manifests itself by creating challenges with verbal communications. Depending on an individual’s role, or desired role, this can prevent a technology rockstar from reaching […]

Back in the days of SUN Microsystem, Scott McNealy asked us to build a big F#@!ing Webtone Switch. At that time, the underlying pieces weren’t there but over last few years the possibilities have opened up. We now have the switch chips from Broadcom and Intel that switch at 1.2Tbps in H/W. From a OS view, 1.2 Tbps of switching at 300ns latency is great but the more amazing thing is PCIe as a control plane which allows 20-40Gbps of control plane B/W where you can change switch registers, L2/L3-tables, TCAMs, etc at nano-second rates.
So after more than three years of work and million lines of C code, the Pluribus Network’s engineering team has the switch chip under Crossbow control. For people who are not sure what I am talking about, in 2005 project Crossbow invented virtual switching inside a server hypervisor and introduced hardware based Virtual NICs and dynamic polling to get 40Gbps of bandwidth through a server OS. The details were published in “Crossbow: From Hardware Virtualized NICs to Virtualized Networks” in ACM Sigcomm VISA 09.
In the goal to benefit from merchent silicon ecosystem and orchestrate the entire infrastructure using Open source OS Continue reading
At Cisco Live 2013 in Orlando, Packet Pushers co-hosts Ethan Banks and Greg Ferro sat with Nexus 7000 champion Ron Fuller and network design expert Russ White to discuss how, when and why you might choose to deploy FabricPath, OTV, or LISP. In particular, we get into the specifics of what each protocol does, where […]

It’s the latest dudilicious episode of Healthy Paranoia! This time we’ll be covering the topic of information sharing and analysis centers (ISAC), specifically in the research and educational networking sector, aka REN-ISAC. Joining Mrs. Y on this adventure into the land of dudeness is Wes Young, REN-ISAC Principal Security Engineer and Architect (El Duderino), Keith […]

A while back, I set about developing a modest configuration templating system for my employer. When I first joined the company, new network devices were being provisioned using configuration templates stored as Microsoft Word files, which, as you can imagine, was pretty painful. Each variable had to be identified and replaced by hand in a tedious and error-prone process. I wanted something better, but also cheap (or free) and simple. So I started building something.
To kick off my crazy project, I first decided to build a web application based on the Django Python framework (the same platform on which PacketLife.net runs). Django and similar frameworks handle most of the mundane tasks involved in writing a web application and allow for rapid prototyping. It also includes a built-in administration interface for creating and manipulating data independent of the front-end user interface. I spun up a modest internal VM running...
Leadership in most companies is not really something explicitly practiced. Generally, a few people who are naturally inclined kind of do their thing while the rest of the leadership ranks sort of ignore the finer points of people management. But why is that the case? And how do you avoid being one of those leaders […]
