Understanding SDN: Services, Commodities and Value

One of the key business drivers behind SDN is to extract value from network connectivity. Before SDN, the functionality derived from connecting servers to switches was inherently valuable. In the post-SDN era, the network has services value instead.

Rant: Certification and Training Does Prepare You For The Real World

A common complaint about vendor certifications is that they don’t prepare you for the real world. Well of course not. Neither did high school or college. And thinking about it, my University education wasn’t much better.

Understanding SDN: Connectivity is Commodity, Services Are Valuable

In short, connectivity is now commodity and it is services that are hard. Understanding this point is key to understanding the SDN market. I take the view that SDN assumes that connectivity is a cheap, low cost and low value business function.

Response: Is TLS Fast Yet?

The impacts of market commoditisation in networking happen are occurring in more segments than just whitebox switches and network operating system. The Internet is steadily progressing towards the exclusive use of HTTP for all communication and bypasses the plethora of protocols that were once in use. And even within HTTP, the current direction of the HTTP/2 protocol standards and it’s proposed of TLS encryption for all protocols will radically change many aspects of the Internet.

At NANOG 60 this happened – “Help! My Big Expensive Router Is Really Expensive!” Over the past few years, we’ve seen the data center switch market explode with commodity chips, open source software, and the concepts of SDN. All we have seen in the routing space has been bigger routers that need more power, cooling, […]

Musing: Working for Companies in Financial Trouble

Your employer is having financial problems. There is a lot of pressure to do “more with less”, to pull together and “do the deals”, close the sales before end of quarter. But really, what do you owe your employer in the modern era ? What is best for you ? This situation is one where the modern paradigm of fail fast, fail often and fail early applies.

Cheap Network Equipment Makes a Better Data Centre

TL:DR A recent project bought a low cost network for the data centre. It cost less one-third of the 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 “fast & cheap networking” could make a big impact on new data centre designs and business attitudes. Plus it was much more satisfying as a professional project. I’m now wondering – is networking too expensive ?

Net Neutrality and Net Reality

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. The technical capability of a person who performs front line technical support is usually set at a low level to match what most customers need. Taking a casual comment as “truth” is wildly unreasonable. Here is more on the reality of net neutrality.
