PlexxiPulse—Spotlight on SDN

Infonetics analyst Clifford Grossner recently released a SDN enterprise study which found that nearly 80 percent of medium and large size businesses plan to implement SDN technology in the data center by 2017. The survey of 153 businesses also revealed that 65 percent of respondents are currently conducting data center SDN lab trials or plan to do so in 2015. Marcia Savage of NetworkComputing cites the Infonetics data and names SDN as a top networking trend in a piece this week titled “What’s Hot In Networking: 7 Key Trends.” We’re excited to see SDN in the spotlight. Marcia’s piece and the Infonetics study are both worth a read before you kick off your weekend.

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

Windows forecast to gradually grab tablet market share from iOS and Android

Once considered a lost cause in the tablet market, Microsoft's Windows will take market share from Apple's iOS and Google's Android in the coming years, according to IDC. Android and iOS are the top two OSes for tablets, with 67.3 percent and 27.6 percent share, respectively, of the 229.7 million units shipped in 2014. Windows had just a 5.1 percent market share, according to research released by IDC on Thursday.

Tablet shipments in 2019 will total 269.4 million, indicating slow growth over the coming years, IDC said.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

Uber knuckles down on security, poaches exec from Facebook

Although it started off as a smartphone app to connect passengers with drivers, Uber Technologies is encountering the same real-world security issues as the taxi industry, includng the need for driver background checks and local regulatory compliance.On top of this there are the risks involved in handling masses of customer and driver data, which became evident earlier this year when the company admitted driver data had been compromised.On Thursday, Uber moved a step forward in its bid to fend off criticism of its security practices by appointing as its first chief security officer Joe Sullivan, a former U.S. Department of Justice prosecutor and, more recently, Facebook’s security chief.To read this article in full or to leave a comment, please click here

Video: IPv6 Myths and Reality

I was talking and writing about IPv6 myths for years, but like any good myth they tend to be pretty robust. Unfortunately, as I explained in the IPv6 Myths and Reality part of IPv6 High Availability Strategies webinar, the reality seems pretty bleak: all we got are longer addresses, half-baked protocols, unsolved challenges, and heaps of confusion.

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.

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
