Lately, two acronyms have been making the rounds: SDN (Software Defined Networking) and ACI (Application Centric Infrastructure – promoted by Cisco). Both have things in common which equate to great marketing: a delightful vision and being difficult to pin down in terms of a crisp definition. Let me try to clarify as best I can with the disclaimer that this is purely my perspective representing Arista, as we celebrate the deployment of our second million ports of cloud networking.
The common view is that SDN is a controller or a set of network management products based on Virtualization Technologies or OpenFlow. At Arista we have a more pragmatic view. To us, SDN is a programmatic suite of open interfaces that allows applications to drive networking actions. Unlike the misconception that SDN is just a controller, I believe SDN is about scaling the control, management and data plane with programmatic and open interfaces. This means customizing the network with high-level scripting and programmatic languages, structured and machine-readable APIs, and standards-based protocols as well as interoperability with controller-friendly networks.
As we enter 2014, we are witnessing the deployment of SDN via Arista EOS and associated programmable network applications such as Advanced Telemetry, Continue reading
Great step by step instructions on how to install Kali Linux in VirtualBox. Plenty of screen shots for those visual people and it really helps tell how the configuration and install should work.

Oracle Virtualbox is an open source virtualization software that can be downloaded from here. It runs on Windows, Linux, Macintosh, and Solaris hosts and supports a large number of guest operating systems . Now we are going to see how to install Kali Linux in Virtualbox. I am using the latest release of Virtualbox for this howto. After downloading and installing virtualbox, open it. Click on New as shown below.
The “Create virtual machine” window opens. Type the name of the virtual machine. select type as Linux and version as Linux 2.6 or Debian. Click on Next.
Then select the RAM for your virtual machine. I put it to 512MB. Make choice according to the memory available in your system. Make sure it is above or same as recommended memory. Click Next.
The size of the hard disk is automatically assigned. We can change it later. I suggest you…

Cloud Architecture Patterns Bill Wilder Networks support applications. Okay, that might seem a little obvious, but it needs to be said from time to time. In that vein, I often find it useful to get a better grip on the applications people are putting on networks, and how they expect the network to behave. In […]
Your company has 3 sites, each with a dedicated border router, R1, R2 and R3.
Site-1 (R1) and Site-2 (R2) have their own internet uplinks, but Site-3 (R3) connects to internet via R2. A GRE tunnel is built between R2 and R3 and applied an MTU of 1440, due to some constraints in the transit network between them. You notice that traffic between same pair of devices works for TCP 1001 but fails for TCP 1002. What's wrong ?
In this article we are going to see two features that improve the load-balancing in the MLPS Core. Why? In the networking when dealing with redundancy of links or paths we are facing the polarization issue. This problem happens when one of the link is congested. Let’s take the example of LAGs, if the hashing […]

The Internet has a trust problem. With the recent revelations of government surveillance, traffic interception and modification, compromised products, and suspect algorithms, we have serious problems. Greg and Ethan spoke to this briefly on Show 175 regarding the pwning of several firewall products by the NSA, but the issue goes much further than just compromised […]

A couple of times in the past month I’ve been asked where a SSL VPN appliance should be deployed in relation to the firewall. In both cases it was relating to the Juniper Secure Access / MAG platform, but best practice should apply equally to any IPSEC or SSL VPN platform, so I thought it […]

Tunneling is the Duct Tape of Networking..It is interesting to realize that a big chunk of network features in Data Center, Service Providers and Enterprises use tunneling in one form or another..It would be fun to imagine a “world” without tunnels! Most known MPLS applications are tunneling techniques, for instance in a VPLS/L3VPN Scenario the […]
