William Gibson is working at the height of his abilities in The Peripheral. Characters move back and forth between near present-day and an unusual post-apocalyptic future, and the book blends high-tech, visionary showpieces with themes of class, opportunity, and economic injustice.

The startup NS1 offers a managed DNS service to accelerate the delivery of Web and mobile content for its customers. It collects network and system telemetry to make intelligent routing decisions.
Next week, the Packet Pushers will be recording a podcast live in front of a crowd in NYC. We’ll be talking SD-WAN deployment with Viptela customers who have been actively rolling out the solution. With this show, we want to move from “what is SD-WAN?” to “how is SD-WAN working for you?” Sign up to attend this event here:
I’ve recently been working on an implementation of Virtual Router Redundancy Protocol (VRRP) on Linux using Keepalived to provide IP redundancy for some HA Proxy load balancers. I’ve been pleasantly surprised by how simple and easily deployed it is and thought I’d share the details now I understand why it’s the default choice for many. Keepalived was created by Alexandre…
Packet Pushers took on an SD-WAN whitepaper sponsored by CloudGenix. There were two main ideas behind this whitepaper. (1) Describe a typical SD-WAN solution. (2) Discuss CloudGenix specifics. When done reading, you should know both what SD-WAN will do for you, as well as how to integrate CloudGenix into your existing WAN with a minimum of disruption.

The Packet Pushers will be at the Open Networking User Group fall gathering at the New York University Kimmel Center in Manhattan, November 4 & 5, 2015. We’ll be attending most of the open sessions, chatting with real people, and doing some live blogging. If you haven’t registered for ONUG yet, you can get 25% off using code Packet25.
As a supplement to the Back to Basics: Power article, I created this cheat sheet to stow away for a rainy day. Next time you need to remember how to calculate wattage, or need to look up a foreign power connector, this will be a handy tool.
In this article I will be walking through some of the elements of power design and management in a context relevant to IT engineers. Although we, as IT-centric engineers, may only deal with electrical power systems once in a while, it can be very useful to understand the principles at work and come in handy…
New to networking? Or maybe just new to Packet Pushers? Want to know which shows will help you build a foundation? Here you go. These shows cover major networking concepts, take on emerging technologies, and provide context for what we might talk about in other shows.
In the last blog, I briefly mentioned about PCE and how BGP-LS can be used as one of the ways to collect the topology information. In this blog we will explore more about PCE, the problems it tries to solve and different elements of PCE. But before we go any deeper, I do want to…
Dell sees the PC is part of a comprehensive strategy to serve customers from the end point all the way through to data center infrastructure.
6WIND, a Packet Pushers sponsor, has been helping get the most networking performance from x86 hardware, making the acceleration software that other companies could use to make the most of their standard servers with multi-core CPUs and Linux. 6WIND has recently taken a further step, offering its own VNFs and virtual networking acceleration software packages to end users like you and me. For example, the Turbo Router and Turbo IPSEC appliances compete with virtual routers from Cisco and Brocade. 6WIND will be appearing on the Packet Pushers Priority Queue podcast near the end of October 2015.
Introduction Working as an Cloud Architect with Cisco means I get the chance to talk to many different customers and discuss their challenges and pain points. One that continually comes up is what should be fairly simple, adding a new network segment to their data center network. It used to be that a network team…
I’ve got a lot of questions about the Dell/EMC merger. I plan to ask them at DellWorld, and I hope to get good answers.
Brocade and Big Switch offer subscription and capacity pricing models for network hardware. Could Cisco follow?
The SD-WAN vendor scrum grows; an increasing number of companies are contending for a place in your WAN traffic patterns. Here’s a list of the companies (some of whom are Packet Pushers sponsors) I’ve heard present about their SD-WAN products, sorted alphabetically.
We wrote this introductory guide to help those considering Packet Pushers community podcasting understand what is required. This is not a detailed list of everything you will need to know. Rather, this guide shares enough information to get you started. You’ll still have to do a bit of Googling, research, and decision making of your own. We hope this helps. Happy podcasting!
Machine learning is an emerging technology that could significantly affect networking, including security, predicting the effects of changes, bug detection, and more.
Savvius has launched a new monitoring appliance, Insight, that integrates with Splunk and can capture packets for forensic analysis.
The Datanauts Podcast is looking for enterprise infrastructure folks who have worked on a project to migrate applications from in-house to the cloud. Interested in being a guest? Ping me — [email protected] — and let us know. You can be anonymous if you like, and you don’t have to use your company name.
This post will cover several most common QoS configuration techniques for Multipoint VPNs. Focus will be on FlexVPN DMVPN, however most of the conclusions will be applicable to the traditional DMVPN as well.
Xirrus is launching a new security feature to encrypt wireless connections between a device and an AP on a public Wi-Fi network. While it’s easy to use, it does have limitations.
The impact of open networking on the enterprise will be a hot topic at ONUG and the ONUG Tech Field Day Extra. I’ll be reporting from both events.
This article is the first in a new mini-series where I will be doing semi-deep dives on some of the simpler, but often overlooked, aspects of network and datacenter engineering. Approx Reading Time: 3-4 Minutes It is quite commonplace these days to see equipment mounted incorrectly in a rack. Even though we are not mechanical…
This Week On The Internet looks at some unusual IoT malware, why breaks are important, how to become a pro gamer, and vegetarian propaganda.
