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
Show 231 – OpenFlow’s Possible Futures with Curt Beckmann
Seen as a unifier and enabler in its early days, OpenFlow has come up against some adoption barriers in the form of silicon challenges and vendor-specific extensions that has resulted in a marketplace of OpenFlow options awash in inconsistency. How does OpenFlow rise above this current state of things? Or does it? The Packet Pushers discuss with Curt Beckmann.

ISIS Link-Group
Introduction On the Core or Edge network, we need more and more bandwidth. For a large service provider, in some parts of the world it’s quite expensive to upgrade links, .ie from 1Gb/s to 10Gb/s. There are two alternatives: aggregate the links either on layer 2 or by doing Layer 3 ECMP. With layer 2 […]

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
