CCIE Recertification + Certification News 2015
The last time I re-certified, it took me three times to pass the CCIE R&S written exam. While that exam is a challenge that many people fail to pass the first time out, I felt like I was getting rusty on some fundamentals. Three times was not the end of the world, but the effort felt forced. I wanted a refresher.Show 259: Don’t Forget The Basics
In Packet Pushers Weekly Show #259 (two hundred and fifty nine, really?), Greg Ferro and Ethan Banks have a wide ranging discussion about several different things that have been on their minds. Perhaps the biggest idea in this discussion is "Don't forget the basics."

Would I take Wireshark training?
If the buck stops with you when it comes to troubleshooting strange and bizarre application behavior, you’ll want to be able to use a packet capture tool effectively. Wireshark is ubiquitous; most network engineers use it. Wireshark has an active user and development community. Plus, there is a commercial variant through Riverbed if you care to go that route. Therefore, I view Wireshark as a safe packet analysis tool to spend time learning intimately.Show 258: Application Centricity With Kemp Technologies (Sponsored)
Kemp Technologies joins the Packet Pushers for this sponsored episode to talk about how application and network owners can leverage SDN, NFV, and hybridity to deliver applications more effectively.

PQ 58: Alibi Routing With UMD’s Dave Levin
In this podcast, Packet Pushers co-host Ethan Banks gets a bit into the weeds with University of Maryland's Dave Levin in this detailed discussion of Alibi Routing, a privacy-driven research project to prove that traffic flowing between a particular source and destination did not traverse a specific geographic region.

A Few Points About VMware EVO SDDC Networking
A Packet Pushers listener that heard us chatting about VMware's EVO SDDC solution raised a few concerns about the networking functionality in the current version of EVO SDDC. I was able to talk briefly with Krish Sivakumar, Director of Product Marketing, EVO SDDC & Ven Immani, Senior Technical Marketing Engineer, EVO SDDC at VMware to help clarify some of the issues.Interop 2016: Introducing The Future of Networking Track @interop
For the last several North American Interop conferences, I have been the Infrastructure track chair or co-chair. For Interop Las Vegas 2016, I will be doing something else. Greg Ferro and I are working together to create a new premium track titled The Future of Networking.PQ Show 57 – Improve Your Home Internet Performance Using CoDel
Rich Brown chats with Ethan Banks about CoDel, an algorithm specifically designed to minimize the impact of bufferbloat. Rich and Ethan explain how CoDel works, and discuss the head-drop principle, sojourn times, TCP ECN, and more. This is a nerdy look at how your modem handles buffering, and how you can improve your home networking experience.

The FCC Might Make It Harder To Use Wifi Firmware Of Your Choice
There's an ongoing issue in the wifi world where the FCC has proposed some new rules. The rules could effectively prevent using third party firmware in a wireless device. If this is a concern to you, you can share your thoughts on the issue with the FCC, at least until 9-October-2015.Google Plus Is Mouldering
A quick search for “Google Plus is dead” reveals a number of recent articles about the pending death of the social media platform. It’s not fair to say it’s dead as yet. But it’s certainly mouldering. I took an informal survey on Twitter, LinkedIn, and Slack, asking folks if they were still using […]What Does It Mean When A Project Has Been Forked?
Open source projects that involve lots of folks sometimes run into conflicts. Should the project go in direction X, or direction Y? Is feature A more important, or feature B? And so on. Sometimes the concerns around an open source project are more pragmatic than pedantic. Should we, as a commercial entity, continue to use this open source project as is, or go in our own direction with it? The keyword to look for in these circumstances is fork.Citizens of Tech Podcast Has Re-Launched!
My friend Eric Sutphen and I started the Citizens of Tech podcast using some spare capacity on the Packet Pushers platform to see what folks thought of the idea. We received lots of positive comments from the audience. Several of you stated that Citizens of Tech quickly became one of your "must listen" shows. With warm, glowing feelings of audience love in mind, we've opted to give the show a site of its very own! http://citizensoftech.comBreach Presumption: The East-West Data Center Security Problem
A recurring trend in security briefings I've taken over the last year is that breaches are assumed. If you don't assume your infrastructure has been breached, you're ignorant, and probably willfully so. Ostrich, meet sand. A weird response my brain had to this is to ponder that if we've lost the war, why are we still fighting?Interoperate or Die: On Brocade & Open, Standards-Based SDN
During a recent briefing with Brocade about the 2.0 release of the Brocade SDN Controller product, I took the opportunity to clarify their commitment to openness in the software defined networking world.Centralized vs. Distributed SD-WAN Functions
In the world of idealistic fantasy, an software defined network of whatever kind would centralize all functions. Pesky reality gets in the way of idealism, and so it is that we find full centralization to be an impractical idea.Datanauts 007 – Decoupled Storage Architecture
While cruising in our Galaxy-class starship to another data center, we’ve hit a storage scaling issue. There’s no way to add any more performance to our antimatter storage array! The chief engineer suggests that we perform a saucer separation to decouple capacity from performance, which will allow us to scale the two requirements individually. Release the docking latches, and let’s hope this maneuver can save us! Satyam Vaghani of PernixData joins the Datanauts for this discussion of decoupled storage.

Show 250 – How To Document A Network
A favorite topic among network engineers, documentation is a source of both wonder and horror. Network documentation is difficult to get right. How much detail is enough? How old is that diagram, really? Can't this be automated? Wait, the automated generator spit out *that*? In this show, the Packet Pushers along with former guest Dominik discuss their documentation experiences, good and bad. What have we gotten right? What have we gotten wrong? What's been worth the trouble? What was a waste of time? What did we wish we'd documented before we really needed it?

Datanauts 006 – Assessing IPv6 Readiness
New IPv4 address space is almost gone from the global market. Organizations need to introduce IPv6 into their environments to ensure uninterrupted business operations with the rest of the world. Yet, implementing IPv6 is not as simple as firing up a routing scheme. How does an organization know if it’s ready? Special guest Ed Horley joins the Datanauts in this discussion.
