Key Attributes of a Software-Defined Infrastructure
We define the specific attributes of an effective SDx infrastructure and look at how they enable real-world SDx solutions.

Back in 2011, I ran a short 1-question survey, asking readers to rate the importance of various factors when selecting a wireless LAN vendor. The results from that survey are located here:

The discussion of "what matters most in WLAN success" came up again recently during a conversation I had with Lee Badman on twitter.
@revolutionwifi is way more about manageability, reliability, and not being admin slave to NMS than having some huge AP whitepaper BS

I thought it would be a good idea to run the survey again. Please take a moment to anonymously answer this short 1-question survey. The survey will close at 11:45pm CDT (GMT -5:00) on July 31st, 2015.

Optimized Performance: Increasing Cache Hit Rate
At CloudFlare, we care a lot about serving requests as fast as possible. Files can be served much faster when already in CloudFlare’s cache. Skipping the trip to the customer’s web server eliminates the latency of that connection and saves bandwidth from the connection between CloudFlare and the customer’s origin, and allows us to utilize the full speed of our ultra-fast servers.
By default, CloudFlare only caches static files. However, Page Rules can be utilized to set more files as cacheable. For more information on Page Rules, please see the Page Rules section of our knowledge base.
Items are cached by their full URL, including the query string. However, due to the details of how query strings work, this can lead to some cache misses. There is no RFC which defines that the order of query strings arguments matter, but in some (rare) cases they do. Thus, by default, CloudFlare caches the following two requests separately:
https://example.com/a?color=red&word=hi
https://example.com/a?word=hi&color=red
Introducing Query String Sort
With a newly available Enterprise-level feature called Query String Sort, CloudFlare will first sort the query strings in a URL into a deterministic order before checking cache Continue reading
Network Break episode 43 looks at Cisco's OpenDNS acquisition, the OpenDaylight Lithium release, a global IT spending forecast, and Amazon's s2n open source TLS implementation
The post Network Break 43 appeared first on Packet Pushers Podcast and was written by Drew Conry-Murray.
After the $37B megamerger, Broadcom will have to deal with the realities of its new overlord Avago.
Thanks to a couple of recent conversations, I thought it was time to stir the wireless pot a little. First was my retweet of an excellent DNS workaround post from Justin Cohen (@CanTechIt). One of the responses I got from wireless luminary Andrew von Nagy (@RevolutionWifi):
This echoed some of the comments that I heard from Sam Clements (@Samuel_Clements) and Blake Krone (@BlakeKrone) during this video from Cisco Live Milan in January:
During that video, you can hear Sam and Blake asking for a few features that aren’t really supported on Meraki just yet. And it all comes down to a simple issue.
Meraki has had a very simple guiding philosophy since the very beginning. Things should be easy to configure and work without hassle for their customers. It’s something we see over and over again in technology. From Apple to Microsoft, the focus has shifted away from complexity and toward simplicity. Gone are the field of radio buttons Continue reading
While I support certifications, they also make me grouchy. Sometimes they make me really, really, grouchy, in fact — probably more grouchy than I have a right to be. You’ve probably heard the complaints a number of times.
For instance, there’s the problem of paper tigers, people who gain the certification but don’t have any real experience with the technology, or don’t really understand the technology. Paper tigers are bad, of course, but they’re generally easy to detect through a rigorous interview. In fact, paper tigers exist without the certification; it’s entirely possible for a solid resume to lead to a candidate that doesn’t have the skills advertised. Degree’s don’t really prove much, either, and it takes four years to get one of those (in theory), so I don’t know how much whining about this problem — as real as it is — is going to help.
Tony Li had a counter to this — he used to sit with a candidate’s resume in hand asking questions, and lining through skills he didn’t think the candidate actually had. At the end of the interview, he would hand the resume back to the candidate and say, essentially, “there, I fixed it Continue reading
