Can the Internet be the “Cloud Network” ? If so, when could the transition happen (if it hasn’t started already) ?
Supposition/Hypothesis As a technology, the Internet has strikingly similar properties to sharing Compute and Storage as ‘Cloud’. A large pool of resource that can be used or shared between many parties. The total pool of resource is dynamically allocated. Internet bandwidth is shared between all users and access is determined by bandwidth purchased at the network edge

Being a Network Engineer is a hazardous and even dangerous profession yet the Health and Safety division doesn’t seem to care about the network damage and prevention.
It’s time for us to stand up and start our own ITIL-compliant safety campaign. I’ve prepared the following handy sign for you to print and place on your cubicle wall to remind you to be safe out there.

No matter how hard the clouderati click the heels of their brogues together and repeat “public cloud is better” , the simple fact is that most companies have large amounts of IT infrastructure that works just fine and is profitable. To make matters worse, the cost of transformation exceeds the potential financial return while creating […]

Frame Relay was to teach multipoint networking to upcoming engineers and we recently abandoned on the curriculum. Now it’s back in MPLS-TP.

It’s a constant and oft repeated fallacy that software on x86 servers will never forward packets at speed. Here is Vyatta explaining why their software will be able to go past 100 Million Packets Per Second this year on standard COTS hardware.

Steve Marquess who manages the business side of the OpenSSL Foundation talks about the shabby state of corporate support for open source development. I want to call out this paragraph first (although many other are more interesting), about the courage and discipline it takes to publish your work in the face of fear of public […]
I was asked to describe how Arista has been able to penetrate the networking switch market relatively quickly. Arista was founded in 2004 and ten years later has achieved a competitive position against all the major vendors in networking and specifically against Cisco who has a dominant market position. Most vendors develop product like an […]
This article from the Association of Computing Machinery and written by no less than Paul Vixie. It is a detailed review of the basic facts of the Internet being smart at the edge and dumb in the middle. By design, the Internet core is stupid, and the edge is smart. This design decision has enabled […]
Well deserved Overall Best of Interop (in my opinion) for OpenDaylight Hydrogen release. As the IEEE and IETF fail deliver on innovation we are turning to open source for real progress & change in networking. While the Open Daylight Hydrogen release is a bit rough, it deserves the Best of Interop award for the reasons […]
Some time ago I wrote that FCoE would have problems on 10GBaseT due to relatively high error rates of 10GBaseT deployment. New information suggests that this problem is solved under certain circumstances.
I’ve unearthed and updated a guide to creating network diagrams in Visio. I wrote the first versions in 2010 using a custom software and finally worked out how to export the data. If you ever wanted to
Who doesn’t love sausages but have you ever made them ? It’s messy,
In a recent project, I noted an astonishing difference in price of the optical and copper cabling assemblies associated with 10Gigabit Networking. I conclude that some companies are including a “license fee” in the cost of these components and making the overall cost harder to determine.
What the best question to ask your future employer in a job interview ?

Back in 2009, while working on a network diagram in Visio, a fellow worker asked me to show him how I did certain things. I thought this a bit strange at the time, but when other co-workers started asking the same questions I was surprised. Some of them got quite excited and said nice things and it … [Read More...]
Lede: I doubt that anyone bought a Vblock because it was a market leading networking strategy. I've been a supporter of VCE in the past but I'm doubtful that choosing Cisco ACI is good strategy for customers. My view is that most customers buy VCE Vblocks as a VMware platform. What VCE offers is a … [Read More...]
TL:DR A recent project bought a low-cost network for the data centre. It cost less one-third of the market leader & half the cost of a well-known merchant silicon vendors. As a result, it is planned to last for two, maybe three years before it will be replaced. From this project I learned that … [Read More...]
Recently, Dave at DavesBlog made some rather startling observations that Verizon is throttling Netflix traffic, backed up by a comment from some low level help desk staffer that this is true. Taking a casual comment as "truth" is wildly unreasonable. On the Internet, it is very hard to pick the … [Read More...]
I've been digging deeper into the SDN architectures over the last few days and there may be a pattern starting to emerge. I'm currently figuring that there are four broad classes of SDN technology that you can fairly neatly classify the current products from vendors. I'm classifying SDN Solutions … [Read More...]
Most people refer to the “Data Centre Network” as though it was a single network. In practice, data centres have a number of individual networks. Each network is specifically designed for a specific purpose and function. A typical data centre network design has about five individual networks that … [Read More...]
I was eating the last of my toast as I sat down into the driver seat of my "CloudCar". Customer visit at 09:30am. As I slipped my SmartPhone into the cradle, the dashboard screen came to life and opened the NavSat app with an error message that my maps were out of date and would I like to download … [Read More...]
The rise of Software Defined Networking has led to a steady stream of emails from network engineers asking whether they need to learn to programming in the future. After consideration, I currently think that the answer is mostly no but some percentage of networking people will gain and use specific … [Read More...]
