When it comes to NAT, network engineers love it, they hate it, or the love to hate it. In this episode, Tom Hollingsworth and Nick Buraglio join us to talk about NAT, why it exists, and its continued role in networking.

Tune in Tomorrow, May 31st, at 10 am PDT/ 1 pm EDT for a FREE live webinar with expert instructor Keith Bogart (CCIE #4923).
About This Webinar:
Understanding the logic of 802.1d and how it builds a loop-free “tree” is critical to passing any Cisco certification exam. Presented by INE instructor Keith Bogart (CCIE #4923), this session will take you through that logic so that, given any bridged/switched layer-2 network, you can predict what tree will be formed. Ask questions live with an experienced industry expert!
Understand business requirements before jumping into a network design in order to ensure they're aligned, networking expert says.
As discussed in a previous blog post, IETF designed EVPN to be next-generation BGP-based VPN technology providing scalable layer-2 and layer-3 VPN functionality. EVPN was initially designed to be used with MPLS data plane and was later extended to use numerous data plane encapsulations, VXLAN being the most common one.
Like any other BGP-based solution, EVPN uses BGP to transport endpoint reachability information (customer MAC and IP addresses and prefixes, flooding trees, and multi-attached segments), and relies on an underlying routing protocol to provide BGP next-hop reachability information.

Once upon a time there were networks and inter-networking, which let carefully managed groups of computers talk to each other. Then with a capital “I” came the Internet, with design principles that ultimately enabled devices all over the world to interoperate. Like many other people, I have often thought about the parallels between networks and blockchains, between the Internet, and something we might call ‘the Blockchain’ (capital ‘B’). In today’s paper choice, Hardjono et al. explore this relationship, seeing what we can learn from the design principles of the Internet, and what it might take to create an interoperable blockchain infrastructure. Some of these lessons are embodied in the MIT Tradecoin project.
We argue that if blockchain technology seeks to be a fundamental component of the future global distributed network of commerce and value, then its architecture must also satisfy the same fundamental goals of the Internet architecture.
This section of the paper is a précis of ‘The design philosophy of the DARPA Internet protocols’ from SIGCOMM 1988. The top three fundamental goals for the Internet as conceived Continue reading

Welcome to the fourth installment of our Windows-centric Getting Started Series!
One of the duties of most IT departments is keeping systems up to date. In this post we’re taking a quick look at using Ansible to manage updates on your Windows nodes. Starting with a small example of six Windows machines, we’ll show an example of a play against those hosts. We’ll share the full example at the end.
Managing Windows updates is something that can be understood and customized quickly with Ansible. Below is a small-scale example of running updates on hosts with some flexibility in what gets updated in the process. The example here is assuming a domain exists and the hosts are being passed domain credentials. If you’re looking to test this example, be sure to read Bianca’s earlier Getting Started post on connecting to a Windows host.
Because this example is running against exclusively Windows machines, the information needed to connect can be included in the inventory file:
[all:vars]
ansible_connection: winrm
ansible_user: administrator
ansible_password: This-Should-Be-a-Password!
The example hosts include three groups of servers, two in each group. There are terminal servers, application servers, and directory servers. For the purposes of Continue reading

Welcome to Summer 2018! It’s been nearly one month now since our CEO Pat Gelsinger announced the Virtual Cloud Network vision at Dell Technologies world in Las Vegas. Essentially the reveal (in my personal opinion) was focused on raising awareness that VMware has now delivered to the market what many of you have heard for quite some time now as “the vision” for networking and security, whereas NSX has become an integral part of many various parts of your business:
Enter stage left, the Virtual Cloud Network. VCN builds upon the fundamentals you’re already familiar with from NSX—these include (but are not limited to) integrated security, consistent connectivity, and inherit automation, but really focuses on tying together an end-to-end architecture that allows our customers to deliver applications and services everywhere. Our customers have asked and we have listened… the demand for any infrastructure, any cloud, any transport, any device, and any application has drastically changed the landscape and technologies associated with building/architecting and having a modern enterprise network.
We’ve been quite busy over the past month with lots of interest coming from partners and customers wondering what this really means. Well today the wait Continue reading
Silicon Valley has rules about shipping faulty, incomplete products for the first version.
