This press release from Huawei really grabbed my attention because it’s an MPLS enabled router that is finger sized and built for carrier networks.
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.
Dual 100G interface and 24 MILLION flow table entries for Open vSwitch ? And flow setup rates to match.
As someone who knows that Amazon AWS is a really expensive method of buying compute & storage, I was much amused by the following slides from a presentation by Terry Wise, Director, Worldwide Partner Ecosystem during a recent conference. You might enjoy a good laugh too.
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.
100% utilisation means that you are a traffic jam in the workflow. Don’t overcommit yourself.
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.
I’m really pleased that Interop have asked me to talk more about blogging and to go deeper on the topic and the result is a new session – Interop Las Vegas – How to Be a Tech Blogger.
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, […]
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.
Netronome makes silicon that accelerates networking by enhancing the network adapters to very high performance. Want to run Open vSwitch at 15 million flow setups per second ?
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 ?
I’ve just published the second show in a new podcast called “The Coffee Break”. My co-host is Andrew Conry-Murray from Interop (and previously Editor-In-Chief at Network Computing) and we talking about industry analysis.
The share price for Infoblox fell by 50% yesterday. Some thoughts on what happened and why.
HP Sentinel is an SDN Security application that combines a reputation database, HP VAN Controller and OpenFlow to build a Campus security solution. Here is a quick overview of the process and how you can mix existing security technology with standards-based OpenFlow/SDN to provide a useful campus security tool. This product is expected to reach the market later this year.
Dell and Cumulus Linux have announced a distribution agreement Dell will also resell the Cumulus Linux network OS, running on the Dell Networking S6000, and the Dell Networking S4810 fixed configuration switches. Hardware Support : These Dell switch products are based on the Broadcom Trident chipset so Cumulus doesn’t have to do much/anything to support the […]
This video from the OpenCompute conference a few weeks ago has Andy Bechtolshein and Marc Andreesen was rather good fun. Andy Bechtolshein is the driving force behind Arista and many other hardware startups and clearly believes that software is only good when the hardware is better. Marc Andreessen states that software will take over the […]
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.
A few months back, Der Spiegel published a carefully selected cache of documents about the NSA Exploit Kits used to compromise a wide range of commercial network and security hardware and software. I haven’t seen anyone discussing the implications for commercial espionage. NSA Exploit Catalog A few months back, Der Spiegel published a carefully selected […]
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 into three categories of Micro, Centi and Kilo as well as classifying physical devices for SDN systems into three classes of Breve, Medius and Magnus.(Yeah, OK, I’m not good at names.)
