Arista Jumps into Open Networking — or Do They?

On March 31 Arista announced it will offer its EOS operating system as a subscription license separate from its switch hardware.  While the rest of the industry is realizing disaggregation of hardware and software for the sake of customer choice and innovation, Arista’s “disaggregation” is only a new pricing model. Arista hardware and its EOS operating system remain locked. Customer choice is limited to pricing models.

That is not open networking. And it’s not what customers need. This is an open pricing model at the best.

Currently Arista sells its hardware and software as a single bundle, but with this new pricing model, Arista claims it gives customers a better way to balance their CapEx and OpEx budgets. Arista also says this will let customers scale their cloud deployments as they want, paying for their network resources only as they consume them and — given the subscription service — helping them avoid exorbitant upfront investments.

Disaggregation?

Is Arista opening their pricing model because of growing industry support for open networking? Their announcement nods towards a “disaggregated offering,” but EOS still requires Arista hardware, and Arista switches still require EOS. Customers can buy the hardware/software components separately, but they still can’t Continue reading

Microsoft Surface team to brave Reddit on Friday

Microsoft's Surface tablet team, fresh off introducing a new lighter and thinner model this week, will take its chances with the Reddit crowd on Friday.Things got a bit rough for the team about a year ago when it dipped its toes into the sometimes dangerous waters of Reddit's Q&A free-for-all, dubbed Ask Me Anything (AMA) following the release of the Surface Pro 3 tablet. Among other things, Microsoft was taken to task for charging separately for the keyboard/cover. However, the Surface Pro 3 has become something of a hit, pulling in a reported $900 million-plus in revenue, according to market watchers.To read this article in full or to leave a comment, please click here

Under one percent of Android devices affected by potentially harmful applications

Based on data collected by Google, less than one percent of Android devices had a potentially harmful application installed last year. This includes devices on which users have installed applications from outside the official Google Play store.The data was collected through a feature called Verify Apps that was first introduced in Android 4.2 back in 2012. The feature, which was also backported to Android 2.3 and higher in 2013, checks locally installed applications for potentially harmful behavior regardless of whether they were downloaded from Google Play or other sources.Verify Apps initially scanned applications only at installation time, but since March 2014 it also performs background scans, so it can later detect malicious applications that weren’t flagged when they were initially installed.To read this article in full or to leave a comment, please click here

How to use MiniEdit, Mininet’s graphical user interface

The Mininet network simulator includes MiniEdit, a simple GUI editor for Mininet. MiniEdit is an experimental tool created to demonstrate how Mininet can be extended.

MiniEdit-503b

To show how to use MiniEdit to create and run network simulations, we will work through a tutorial that demonstrates how to use MiniEdit to build a network, configure network elements, save the topology, and run the simulation.

Set up Mininet

You should already be familiar with Mininet before trying to use MiniEdit. If you need some basic information about Mininet, please read my Mininet overview.

Before starting this tutorial, you should have already started the Mininet VM and connected to it via SSH with X forwarding enabled. If you need to learn how to do this, please read my post describing how to set up Mininet. If you want to use Mininet on an Amazon EC2 server, please see my post about installing Mininet on Amazon EC2.

Start MiniEdit

The MiniEdit script is located in Mininet’s examples folder. To run MiniEdit, execute the command:

$ sudo ~/mininet/example/miniedit.py

Mininet needs to run with root privileges so we started MiniEdit using the sudo command.

MiniEdit user interface

MiniEdit has a simple user interface that Continue reading
