The IoT needs simulation to grow

Without simulation, complex systems would fail. Satellites would not reach an accurate orbit, semiconductor circuits would not function, and bridges would not carry the load. Businesses and governments would not invest in these projects without robust simulation software. And without a simulation proving value and functionality, IoT networks of hundreds of thousands or millions of inexpensive devices adding up to large capital investments will not be built.Researchers from the University of Bologna published an analysis of IoT simulation and a smart cities vehicular transportation system case study (pdf). They recommend a networked simulation of orchestrated simulators that model specific IoT features that fit the diversity of IoT devices and use cases.To read this article in full or to leave a comment, please click here

RFC8200: IPv6 Is an Internet Standard

You wouldn’t believe it – after almost 22 years (yeah, it’s been that long since RFC 1883 was published), IPv6 became an Internet standard (RFC8200/STD86). No wonder some people claim IETF moves at glacial speed ;)

Speaking of IPv6, IETF and glacial speeds – there’s been a hilarious thread before Prague IETF meeting heatedly arguing whether the default WLAN SSID should be IPv6-only (+NAT64). Definitely worth reading (for the entertainment value) over a beer or two.

Cray buys Seagate’s enterprise storage array business

Supercomputer specialist Cray announced it is acquiring Seagate’s ClusterStor HPC storage array business for an undisclosed sum as part of a strategic deal and partnership. The deal should close in the third quarter. Cray will take over development, manufacturing, support and sales of the ClusterStor product line, picking up 100 Seagate employees in the process. Seagate acquired Xyratex, the maker of ClusterStor for $374 million in 2014. Cray already sells ClusterStor under its Sonexion scale out Lustre arrays. Sonexion is based on ClusterStor, so it simply comes in-house. Cray is the biggest OEM for the ClusterStor line. Even though Cray was already knee deep in ClusterStor, it brought the technology in-house so it can reduce margins and push further on development to align with its strategy, which sounds like it intends to compete with Dell EMC. To read this article in full or to leave a comment, please click here

VMware NSX is something something awesome

At times I have trouble focusing on writing articles for some of the presentations I am exposed to at Tech Field Day. Because of that, I really wanted to try something different. This article is more of my free-formed thoughts about NSX and why I’m excited to deploy it at my current $job. From the time I heard that the NSX team was going to be presenting at TFD15 for 4 hours, I knew that I would be writing this article because. Unfortunately it took me far too long to gather up this half formed thought.

First things first – NSX and Micro-Segmentation

I love the concept of Micro-Segmentation that NSX enables. Think of NSX as a virtual distributed firewall that is integrated with your hypervisor, but it really is so much more. This allows you to connect a security policy directly to the vNIC of your guest VM’s. Attaching it to the VM allows that policy to follow the VM anywhere, and everywhere it goes. You don’t have to worry about inter- or intra-VLAN segmentation as all of that is done on each vNIC. On top of that, NSX’s firewall is PCI DSS 3.2 compliant! Another rather compelling Continue reading

Bespoke Processors and the Future of Networks

As I spend a lot of time on Oak Island (not the one on television, the other one), I tend to notice some of those trivial things in life. For instance, when the tide is pretty close to all the way in, it probably is not going to come in much longer; rather, it is likely to start going back out soon. If you spend any time around clocks with pendulums, you might have noticed the same thing; the maximum point at which the pendulum swings is the point where it also begins swinging back. Of course my regular readers are going to recognize the point, because I have used it in many presentations about the centralization/decentralization craze the networking industry seems to go through every few years.

Right now, of course, we are in the craze of centralization. To hear a lot of folks tell it, in ten years there simply are not going to be routing protocols. Instead, we are going to all buy appliances, plug them in, and it is “just going to work.” And that is just for folks who insist on having their own network—for the part of the world that is not completely Continue reading

Is IoT really driving enterprise digital transformation?

The Internet of Things is often thought of as primarily an industrial and consumer technology. But there’s a growing consensus that IoT is also taking a leading role in digital transformation in a wide variety of business applications in locations around the world. Survey says: Global enterprises bullish on IoT A recent study by satellite communications vendor Inmarsat, for example, reveals that IoT is the top priority for 92 percent of the more than 500 enterprises surveyed across the globe. Titled “The Future of IoT in Enterprise 2017,” the report assembles responses from companies that have more than 1,000 workers in agritech, energy production, transportation and mining.To read this article in full or to leave a comment, please click here
