4G Breaks Through That Great Chinese Wall
The popularity of 4G mobile services in China continues to take off and subscriber growth shows no signs of slowing.
With almost 576 million 4G customers at the end of June 2016, China is home to twice as many 4G users as the next largest market (the U.S.). But why?
Happy Internaut Day! On August 23, 1991, users accessed the World Wide Web for the first time, paving the way for the internet that we turn to for the latest and greatest cat gifs.
Network specialists herald the software-defined wide area network (SD-WAN) as the most significant advancement in corporate networks in years.
Here’s why: SD-WAN dynamically routes traffic among multiple connections based on the performance of each link and the priority of applications using the network.
Connections may include relatively expensive, high-performance MPLS VPN links, lower-cost dedicated internet access, or cheaper, “best efforts” business broadband service. Accordingly, SD-WAN dynamically optimizes connectivity cost and application performance. (More on that here.)
Faced with the one-two punch of growing bandwidth demand and restricted network budgets, corporate wide area network (WAN) managers are constantly looking to optimize WAN design without sacrificing performance.
Enter SD-WAN.

In Part II of TeleGeography's Mythbusters presentation at SubOptic 2016, Alan Mauldin busted five myths that ranged from whether capacity demand is doubling every two years to a quote from the movie Gravity that the destruction of a single satelite would lead to half of North America "losing their Facebook." In the concluding part of this series, Tim Stronge returns to the stage to take on myths about energy costs pushing decisions about content providers' data center locations, multiple parties building on the same route and "adult" content driving most Internet traffic.

Mythbusters: Revenge of the Cable Myths, Part II
In the first part of TeleGeography’s Mythbusters presentation at SubOptic 2016, Tim Stronge busted myths about NSA surveillance, decreases in connectivity to the United States, and shark attacks on the internet.
In Part II, Alan Mauldin investigates whether submarine cable capacity is doubling every two years, if content providers really need fiber pairs everywhere, if the global network is more resilient than ever before, whether Netflix has huge subsea capacity requirements and the possibility that the destruction of a single satelite would cause half of North America to "lose their Facebook."

Mythbusters: Revenge of the Cable Myths, Part I
TeleGeography’s Tim Stronge and Alan Mauldin returned to the triennial SubOptic conference this year to deliver a follow-up to their popular and humorous submarine cable mythbusting master class from the 2013 event. In just over an hour, Tim and Alan “exploded” eleven of the most prevalent myths about the submarine cable industry. To cover the scope of the master class, we’ll be recapping the entire presentation over the course of a three-part blog series.
