5 ways the IoT must improve to achieve enterprise success

If you think you know the problems facing the Internet of Things (IoT), a new Deloitte report, Five vectors of progress in the Internet of Things, offers a great chance to check your assumptions against the IoT experts.Despite the fancy-pants “vectors of progress” language, the report’s authors — David Schatsky, Jonathan Camhi, and Sourabh Bumb — basically lay out the IoT’s chief technical challenges and then look at what’s being done to address them. Some of the five are relatively well-known, but others may surprise you.To read this article in full, please click here

What’s in a Mutable Field? — We Can’t Tell You

In conversations I often hear people using the word “mutable”. Typically it would be something similar to the following.

The IP TTL is a mutable field and decreases as it traverses a router.

If we look up the word “mutable” we find that it is something that is likely to change.

So the IP TTL is a great example of a mutable field. That value is expected to decrease at each hop throughout the network.

By contrast, IP Source Address, Destination Address, and Protocol would be immutable because it is not normal for those to change. They should stay constant from source to destination.

I know someone might consider something like NAT or PAT to change some of these attributes. While that is true, I still would not consider those mutable fields.

Vagrant + vQFX + Ansible = EVPN-VXLAN Fabric

Did you know that Juniper vQFX images are available in Vagrant Cloud? There is vQFX RE image and vQFX PFE one. You can use only RE image to build simple topologies, or pair every RE with PFE to use more complex protocols. There is also a bunch of examples in Juniper’s github repository.

What is Vagrant? Let me quote official website: “Vagrant is a tool for building and managing virtual machine environments in a single workflow. Vagrant gives you a disposable environment and consistent workflow for developing and testing infrastructure management scripts.” I hope you already knew that. And I also hope there is no need to present Ansible.

I played with this stuff a little bit and created a couple of new examples using full vQFX option (e.g. RE+PFE for every box) – IP fabric and EVPN-VXLAN fabric.

This is really easy way if you want to get yourself familiar with configuration of IP fabric and EVPN-VXLAN on QFX (and some Ansible as well), but don’t want to spend time figuring out how to set everything up in GNS3 or EVE-NG.

Just a few simple steps:

The Internet and related digital systems that the United States did so much to create have effectuated and symbolized US military, economic, and cultural power for decades. The question raised by this essay is whether these systems, like the Roman Empire’s roads, will come to be seen as a platform that accelerated US decline. @The Hoover Institute

Article 13 reverses one of the key legal doctrines that allowed the Internet to thrive: the idea that computer networks are not “publishers” and are therefore not liable for the actions or statements of their users. This means that you can sue an individual user for libel or copyright infringement, but not the e-mail service or bulletin board or social media platform on which he did it. This immunity made it possible for computer networks to open a floodgate of content produced by independent individuals, without requiring service providers to serve as editors or moderators. —Robert Tracinski @The Federalist

The U.S. Supreme Court today ruled that the government needs to obtain a court-ordered warrant to gather location data on mobile device users. The decision is a major development for privacy rights, but experts say it may have limited bearing on the selling Continue reading
