Networking Books Up For Auction – Good Stuff Cheap

I’ve put several of my networking books up for auction on eBay. Lots of CiscoPress titles, but several others as well. Many design guides. Routing protocol coverage such as OSPF, including an OSPF vs ISIS guide by Jeff Doyle. Some are older, what I consider classics. Some are fairly new. Some are targeted at certification seekers. I need to clear some space here in my home library, and would like to move these titles along. Far too many books in my collection, and I’ve gotten what I can from these. Good luck!

SD-WAN Gives Us The Best Path We Always Wanted

In networking, we rely on routing protocols to compute best path. That is to ask, from the perspective of a given router in a routing domain, what is the best way to reach a destination? Best path is typically computed using simplistic metrics like hop count, cost, bandwidth, and delay. Traditional “best path” thinking is effective, insofar as it goes. It scales to a large number of devices and destinations. It is resilient. It is mature. However, it has its limitations. Software defined WAN brings a much more sophisticated metric to the computation of best path.

72% of Networking Performance Statistics Are Misleading

Like my tongue-in-cheek title, performance statistics are often misleading or, at best, meaningless without context. As a savvy consumer of any networking product, you should look at performance statistics as little more than a rough indicator of how a { box | software package | interface } performed under a specific test circumstance. Hint: the tests are usually rigged.

IF { you like this blog } THEN { donate to my annual charitable campaign }

I am raising money for the Mt. Washington Observatory (MWO), a non-profit organization engaged in weather research in New Hampshire. I am joining the 15th annual Seek The Peak fundraiser for the MWO. The idea is simple: hike to the summit, with pledgers backing the adventure. If you’ve gotten value from the Packet Pushers podcast or this blog, I’d appreciate it if you’d donate to my Seek the Peak campaign. For the first three networking vendors that donate $1,000 or more, I’ll have my picture taken at the Mt. Washington summit sign with your wearable and thank you in a blog post here.

Introducing the Citizens of Tech Podcast

Citizens of Tech is not a show about gadgets and apps, at least not specifically. It’s not a show about networking. It’s not a constipated show about IT. Rather, it’s a show for nerds who like science, gaming, books, contrarian thinking, entertainment, space exploration, transportation, energy, complex world problems, and anything else that’s somehow technology-related. Sure, that might include gadgets, apps, IT, and so on, but we’re trying to appeal to a certain kind of mind — probably yours — and not a certain kind of industry.

IPv6 — Still No Love?

When IPv6 becomes a business problem, and not a technical one, it will start seeing serious adoption in the enterprise. A lack of available IPv4 addresses and expensive aftermarket pricing might start driving North America towards broad IPv6 adoption. Finally.

The Present Impact of Open Networking & Whitebox Switching

Dell is all about open networking, and several whitebox vendors had their wares on display at Interop. IP Infusion has released OcNOS, an open networking operating system with a rich feature set right out of the gate. Ethernet switching continues to change. If you are Yet Another Cisco Buyer, do you care? I think you should. There are real dollars at stake. Eventually, it gets silly and/or irresponsible to spend money on Cadillacs.

Network Engineering In A World Of Data Center Haves & Have Nots

If we assume economies of scale, eventually, it may become silly for a business to own lots of IT infrastructure. Why not lease it from cloud providers? They’ll be able to do it cheaper, and besides…they’re experts. I think it’s possible that businesses will eventually migrate most (if not all) of their applications to the cloud.

SD-WAN’s Value Prop Conundrum

My interpretation of the SD-WAN value prop can be boiled down to cost savings, simplified operations, and improved application performance over inconsistently performing WAN links. Here’s the conundrum. An engineer might instinctively recoil at this sort of value proposition.

Is Juniper The Next Cisco?

Juniper flexed its muscles at the Innovation Showcase held in March 2015. What did they talk about? What does it mean for their customers going forward? I perform an introductory analysis.
