Schrodinger's MPLS and Why Predicting the Future is Hard

Predicting the future is hard, especially when it comes to complex markets with disruptive variables that are difficult/impossible to model. In his excellent book Thinking Fast and Slow, Nobel winner Daniel Kahneman provides stark examples of how bad humans can be at doing just that. 

In this excerpt, Kahneman details how he tracked the performance records of 25 professional wealth managers across eight years. He found that “[t]he results resembled what you would expect from a dice-rolling contest, not a game of skill.”

On TEMs: You Can't Benchmark Your Network if You Don't Understand What You're Buying

Let's talk about telecom expense management, better known as TEM.

TEMs are designed to make untangling telecom investments a little easier. For larger organizations with bigger telecom bills, this can be huge for streamlining costs and saving dollars. (More on that here.)

But why bring up TEMs? Why do we think WAN managers might be interested?

COVID-19 and the Impact of Remote Work on WAN Managers

At this point, the spread of COVID-19 seems inevitable in much of the world. Working from home, if possible, is more than just a good idea. It’s a mandate from employers and governments around the globe. 

While many folks are considering the social and business implications of a potentially permanent increase in remote workers, at TeleGeography we’re of course thinking about what this means for WAN and IT infrastructure managers worldwide.

This is How the Average Enterprise is Managing Their Network in 2020

After another year of polling and interviewing WAN managers around the world, the results of our annual WAN Manager Survey are in.

Once again, we connected with networking professionals from nearly 100 companies, focusing on those whose day-to-day role covers designing, sourcing, and managing U.S. national, regional, and global corporate wide area computer networks. 

What'd we discover? Here are some top-line takeaways.

More SD-WAN Adoption, More Data on a Changing Marketplace

SD-WAN has rapidly gained momentum among enterprise customers and the service has moved into a new phase of adoption.

In previous years, WAN managers were evaluating the promise of the technology itself. But today, many already have—or are in the process of—selecting a vendor and rolling out SD-WAN across their global network.

As such, they face a new set of issues in procuring and operating the network.

Analysts Weigh in on Networking in 2020

SD-WAN is still the hot topic among network professionals, but questions remain on how best to implement it. There is more work to be done.

Australian Stakeholders Debate Underlay Network Options Including NBN, 5G

Australia is a place unlike any other. This is true for many reasons, but it’s certainly the case when it comes to Australia’s unique broadband environment.

This made for a fascinating backdrop as the TeleGeography team ventured to Sydney earlier this year for the first-ever WAN Summit in Australia. All that to say, the conversation was unlike those we’ve had in New York, London, or even Singapore, offering new, Down Under-specific insight into WAN management.

SD-WAN Management Costs, Wargamed

In house or outsourced? This is an age-old question for many firms. 

Wargaming Your WAN: Aggregator Broadband & SD-WAN

Elizabeth here again. I’m back for our seventh installment on wargaming your wide area network. This is the series in which we build a hypothetical network, make a bunch of noteworthy changes, chart the results, and then tell you everything we learned.

Three Facts About Network Benchmarking

If we were to take our blog and make one of those word clouds that you saw at every tech summit in the mid-aughts (or on many an inspirational Pinterest board, for that matter), there's one word that would be pretty big. Benchmarking.
