How many times have you received that call or even made the statement that “The Internet is Down?” Or perhaps the “Internet is Slow?” Obviously these statements are very rarely true. As a whole, the Internet is functional and it is FAST. However these statements seem true from the perspective of the individual making them. My frustration is that we never have visibility into the data necessary to assess the health of the Internet from a relevant, holistic perspective over time. As a result, consumers and providers have a limited view of problems that randomly present in this manner.
When I think about the impact Internet hiccups have on me, I realize that I could do things much differently if it delivered consistent reliability. Even if it wasn’t as reliable as infrastructures like the PSTN, having some semblance of trust in knowing when and how my connections might fail or degrade would help. The resulting improvements would allow me to use more robust tools like video and voice over the Internet and put my cell phone away. I can’t tell you how many times I’ve spent hours chasing ghosts. These transient issues tend to get resolved when they worsens and the root cause is more easily identifiable. Increasing the trust we have in our services would materially change the way in which we use them. Continue reading
Understanding everything about routing design is no brainer, especially if you have the chart below on your wall. The table below highlights the pros and cons of each routing protocol. Of course, you need to consider the design attributes shown in Figure A before embarking on routing design. Should you like the comparison of the […]

It was almost a year ago that I set forth the idea to start writing all my blog posts in Markdown. I’ve been doing my best to keep up with that throughout the year and now I’m fifty Markdown posts into my goal. How is it working out so far?
Learning to write in Markdown took some adjustment. Before, I had just used the web editor or the occasional HTML editing suite to write my posts. Most of the HTML was hidden. With Markdown, you have to think about what you’re going to do before you start writing it. Where are the links going to appear? How is your post going to be organized? Putting a bit more thought into your post gives you more structure to your thoughts. That’s something that’s helped my writing a bit.
The table layout for the 2015 Cisco Live Twitter List really wasn’t all that difficult either. Once I put the initial code together, it was just a simple copy/paste job after that. I’m toying with the idea of putting all my notes into Markdown as well. But given how terrible I am with taking typed notes that may not happen.
I was doing some testing on a 3750X and saw that the http and http servers were enabled. I knew you could apply an ACL to restrict HTTP access, but had assumed that the HTTP security was an optional extra on … Continue reading

I recently came across a design in which GRE tunnels were built utilizing HSRP VIP addresses. At first I was unsure of how well this would work so as usual I decided to lab it up. It turns out that this is an excellent counter design to having to place metrics or do any type […]
