Networking Pioneers, Settlers and Town Planners

Can we broadly separate Networking into Pioneers, Settlers, and Town Planners? I’ve been thinking about how to apply Simon Wardley’s PST model to networking. This leads to thinking about how we can encourage networking evolution. The model needs a lot of fleshing out, but I’m interested in what others think.

Pioneers, Settlers and Town Planners (PST)

Simon Wardley has written about “Pioneers, Settlers and Town Planners (PST)” in many places – e.g. here and here. It derives from Cringely’s Commandos, Infantry, Police model (see Chapter 12 of Accidental Empires). It provides a organisational structure, grouping areas based upon their current state of evolution. It recognises that no one operational model works for all parts of a business. You can’t say “We’re using Agile, or Lean, or Six Sigma” – you need to use the appropriate model for each area. Even “Bi-Modal IT” is too limiting, as the divide is too great.

Applying PST to networking

The model is a helpful way of thinking about the role of different groups across a business. It also helps us understand why teams need to evolve over time, Continue reading

LDP Label Allocation Revisited

One of my readers was having an LDP argument with his colleague:

Yesterday I was arguing with someone who works for a large MPLS provider about LDP label allocation. He kept saying that LDP assigns a label to each next-hop, not to each prefix. Reading your blog, I believe this is the default behavior on Juniper but on Cisco LDP assigns a unique label for each IGP (non-BGP) prefix.

He’s absolutely right; Cisco and Juniper use different rules when allocating MPLS labels.

iPhone 7 rumor rollup: Nixing those homely antenna lines; flexible displays on the way?

I thought I very well might need a new iPhone after spending this past week in Delaware at the crazy Firefly music festival during which we had to be evacuated one night because of a tornado warning. But everything turned out well, my iPhone 5 is intact, and now I can take my time awaiting iPhone 6S and iPhone 7 rumors to morph into reality. No more ugly antenna lines on the iPhone? Speculation swirled over the past week about Apple possibly ditching those homely plastic lines across the back of your iPhone…that you probably never noticed in the first place. But the plastic is practical: It allows the phone’s antenna to work by not blocking radio waves.To read this article in full or to leave a comment, please click here

IPv6: Yet Another Post Trying to Urge You to Start TODAY

“Okay, who wants to learn IPv6 and be the IPv6 person for CPOC?”   This was the question asked by our manager to our team back in 2002 when we heard “IPv6 is COMING – GET READY NOW!”   My hand went up almost without me even realizing it. No other hands went up.  Not one. So, by default, it was me.  I was pumped with excitement!  After the meeting I immediately went online and ordered about 8 IPv6 books.  (For those of you who know me… this will not be a shock)  :)

Then what happened? Was 2003 the “year that CPOC got SLAMMED with IPv6 requests”?  Uh…. no. Was 2004? ….. No.    Don’t get me wrong.  People came in with IPv6 in the test plan.  But typically IPv6 was on the list of things to test more as a “checklist” test just to make sure the boxes could do IPv6.

In ~2006 I started believing that this “IPv4 exhaustion scare” wasn’t “real”.  NAT would take care of everything.  If it was “really” that much of a big deal …… people would be doing something serious about it. Continue reading

Samsung will stop blocking Microsoft software updates ‘within a few days’

Owners of Samsung PCs will begin receiving automatic software updates from Microsoft again soon, after Samsung said it will end its practice of blocking automatic Windows Updates on its computers.“We will be issuing a patch through the Samsung Software Update notification process to revert back to the recommended automatic Windows Update settings within a few days,” Samsung said Friday.It said it was committed to providing “a trustworthy user experience” and that it values its partnership with Microsoft.It’s a quick turnaround from earlier this week, when researcher Patrick Barker reported on an auspiciously named application called “Disable_Windowsupdate.exe” that runs on Samsung PCs as part of the company’s SW Update service. As its name implies, the program disables automatic updates from Microsoft’s software patching service, and requires people to manually install individual patches if they want to update their PC.To read this article in full or to leave a comment, please click here

Datanauts 002 – Insert Tab A into Slot B with Converged Infrastructure

Converged infrastructure integrates discrete components, such as compute and storage, along with orchestration software, into a package that’s simple to deploy and certified to interoperate. Join Chris Wahl, Ethan Banks, and special guest Stu Miniman as they drill into the origins and benefits of converged infrastructure, how it differentiates from hyperconverged systems, and how the convergence trend will affect IT roles.

Tech throws its weight behind marriage ruling … with rainbows, emojis and software

When the Supreme Court issued its historic ruling on Friday legalizing same-sex marriage across the U.S., many of the biggest technology companies embraced the decision with characteristic flair through social media, on their sites, and with tools that others could use to show their support as well.Companies like Google, Microsoft, Motorola Mobility, Uber and Airbnb, their chief executives, and their venture capitalist funders all took to Twitter to post celebratory tweets about the ruling, often accompanied by the hashtags #LoveWins or #Pride, plus GIFs. Companies also changed the colors of their profile pictures on Twitter to those of a rainbow, conjuring the symbol of lesbian, gay, bisexual or transgender pride.To read this article in full or to leave a comment, please click here

A former executive vice president at Qualcomm was sentenced Friday to 18 months in prison and fined US$500,000 on charges related to a three-year-long insider trading scheme.Jing Wang, 52, of Del Mar, California, also had served as president of global business operations at Qualcomm, where he worked for more than a decade.

AppleCare+ offers easier battery replacements for iPhone, iPad, Apple Watch and more

Owners of iOS devices that aren’t holding a charge are in luck, thanks to a change Apple has made to its support policy.Apple has changed the terms of its AppleCare+ extended warranty to allow replacements for iPhones, iPads, iPods and Apple Watches with batteries that hold less than 80 percent of their original capacity. That’s an upgrade from the previous plan, which only offered free replacements for devices that dropped below 50 percent of their original capacity.The change was noticed Friday in a post by MacRumors, and appears spurred on by Apple’s expectations for its smartwatch. The company has said that it expects the Watch’s battery will take about 1,000 full charge-discharge cycles before it drops below 80 percent capacity, which means that it will last for about two-and-a-half to three years. The changed policy only applies to devices purchased after April 9, so iPhone and iPad owners who got new hardware for the December holidays are still subject to the plan’s previous 50 percent requirement.To read this article in full or to leave a comment, please click here
