Webinar: Multi-Terabit Submarine Cables…Too Big to Fail?

Watch on demand now 

Submarine networks became critical infrastructure long ago.

A subsea cable fault that interrupts 120 Gb/s traffic is a bad thing. But a fault that interrupts tens of terabits of traffic is quite another.

Building the Local Exchange of Content in Africa: Dispatches from AfPIF

For the Internet Society (ISOC), the goal is 80/20 by 2020 in Africa.

IP Transit vs. Peering: How a Network of Networks is Built

What does the Internet look like? Perhaps you’ve heard it described as a veritable network of networks.

While this is true, as TeleGeography’s Senior Analyst Paul Brodsky explains, no single network is big enough to connect every single person and every single computer. So the question remains: how are we really staying connected?

4 Telecoms Articles You Should Read This Weekend

If you’re like us, you’ve saved the best stuff on the Internet for some lazy weekend reading. Our team has four suggestions for telecoms pieces that'll make your morning coffee and your reading queue a little more interesting.

Bandwidth Prices Are Eroding, Volume is Growing, and The Market Spins Madly On

Content network operators account for a growing portion of bandwidth on global routes.

Perhaps by now you’ve read what companies like Google, Microsoft, and Facebook are doing about it: they’re taking primary ownership shares of transoceanic systems, joining consortia, and taking major stakes in carrier-owned cables.

The Case for the Hybrid Network

Hybrid WANs that employ a combination of technologies - such as MPLS and Internet connectivity - have become increasingly popular as enterprise customers and service providers embrace the software-defined WAN.

What is really driving the move to the hybrid WAN?

And what advice do those who have adopted the technology have for those planning a similar transition?

Are All These New Undersea Cables Really Giving Us Faster Internet? Not Exactly.

How many times have we heard that new undersea cables will bring consumers Internet speeds faster than a speeding bullet? (Like this or this or this.)

It has been reported that new cables promise speeds up to 10 million times faster than traditional home cable modems.

But here’s the kicker: there is no increased speed to be found in these submarine cable systems.

SD-WAN Provider Facts for the Modern Network Specialist

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.)

The Scoop on Google's New Subsea Cable (And What it Means for Future Capacity Investments)

Google has joined a handful of carriers to complete a brand new Trans-Pacific oceanic cable – but this is hardly their first venture under the sea.

A Primer For Anyone Who Has Ever Googled “What is SD-WAN?"

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.
