IDG Contributor Network: Performance analysis: Bursting the myth of MPLS performance

Quick question, MPLS or SD-WANs, which would you say offers better performance? For the same bandwidth, we’d assume MPLS. After all, MPLS services are managed for a reason, right? However, as we learned on one recent project, internet performance has improved so much over the years that its performance can rival, even exceed, private WAN services.The situation The project was with a manufacturing company that wanted to see if modernizing its MPLS WAN made sense. The alternative would be an SD-WAN or hybrid WAN.To read this article in full or to leave a comment, please click here

WikiLeaks says it doesn’t collaborate with states

WikiLeaks claims to have many thousands of sources but does not collaborate with states in the publication of documents, its editorial board said late Sunday.The statement by the board of the whistleblowing site assumes significance after the  administration of U.S. President Barack Obama charged that it and other sites had released allegedly hacked emails under the direction of Russia.

A Brief History of the IANA

October 2016 marks a milestone in the story of the Internet. At the start of the month the United States Government let its residual oversight arrangements with ICANN (the Internet Corporation for Assigned Names and Numbers) over the operation of the Internet Assigned Numbers Authority (IANA) lapse. No single government now has a unique relationship with the governance of the protocol elements of the Internet, and it is now in the hands of a community of interested parties in a so-called Multi-Stakeholder framework. This is a unique step for the Internet and not without its attendant risks. How did we get here?

IoT botnets used in unprecedented DDoS against Dyn DNS; FBI, DHS investigating

Infected IoT devices turned into botnets, at least some controlled by Mirai, were used in multiple DDoS attacks against New Hampshire-based internet infrastructure company Dyn. The attacks against Dyn DNS were similar to some thugs shredding an internet address book, since addresses of thousands of websites couldn’t be looked up and users couldn’t be connected to the right servers; by the third wave of attacks, users across the globe had been affected by the massive disruptions.The FBI and the Department of Homeland Security are investigating the attack on Dyn, one provider of DNS services. A spokeswoman told The New York Times that the FBI and DHS “were looking into the incident and all potential causes, including criminal activity and a nation-state attack.”To read this article in full or to leave a comment, please click here

Float Shelf: An elegant way for Apple users to clean up their desktops

I love my iMac. There’s something so elegant and practical about the design and, as a result, many companies have attempted to come up with products that fit the Apple aesthetic but, sadly, most fail. Now, way back in 2012 in a roundup of Kickstarter projects I wanted to get my hands on, I covered the Hand Stylus, a beautifully designed pen-style stylus for tablets that is still my favorite tool for drawing on an iPad. Designed by Steve King, the Hand Stylus was the first of a series of products from his company, Prism Designs, and the company’s latest product, the Float Shelf, echoes the whole Apple look and feel as well as being really useful. To read this article in full or to leave a comment, please click here

dweet.io: A simple, effective messaging service for the Internet of Things

In my last post I discussed Freeboard, a powerful, polished, open source Web dashboard and mentioned that Bug Labs, the creators of Freeboard, also offer a very interesting Internet of Things messaging service called dweet which we’ll look at today.Now, there are many messaging services (for example MQTT) that can be used by IoT applications but few that are really simple and free as well; dweet is, indeed, simple and free though there is also an inexpensive enhanced level of dweet service we’ll get to later.To read this article in full or to leave a comment, please click here
