Observations From an SDN Road Trip

Jun 18, 2013 by Brian Irish

Overture Networks Brian IrishI recently attended Layer123’s “SDN APAC Congress” that was held June 4-6, 2013 in Singapore and Informa’s SDN World” event June 11-13, 2013 in Barcelona, Spain. Below are some of my general observations after sitting through dozens of vendor and service provider presentations on SDN, NFV, and the future of our ever-dynamic industry.

Packet Encapsulation and Link Bonding Protocols

Jun 10, 2013 by Prayson Pate
Overture’s market segment of Carrier Ethernet includes equipment that supports a wide array of protocols and encapsulations.  How these protocols interact with each other can be very confusing.  This blog provides a handy infographic that clarifies the relationships between and among these protocols.

Ethernet Looks at 40

Jun 3, 2013 by Mark Durrett

Last week I attended the 40th anniversary celebration of Ethernet at the Computer History Museum in Mountain View, California.  In this article, I offer a few highlights and several photos from this memorable event. 

 

Giants Still Walk Among Us

May 27, 2013 by Prayson Pate

I read that the Doolittle Raiders recently held their 71st and final reunion.  While Memorial Day is dedicated to those who died while serving in the Armed Forces, I wanted to take the occasion to remind us all that we are about to lose our remaining WWII veterans to the undefeatable enemy of age.  For the moment, these giants still walk among us.

Special Access, Part 2: No Longer Special?

May 20, 2013 by Prayson Pate

Please see last week’s entry on "How Did We Get Here?” for a recap of the history of AT&T.

After the breakup of AT&T, one of the assets that the new RBOCs (now ILECs) had was the copper plant that had been constructed under monopoly conditions.  Part of the deal to enable competitive carriers (CLECs) was providing access to this copper plant and services under the umbrella of “special services”.

Special Access, Part 1: How Did We Get Here?

May 13, 2013 by Prayson Pate

This blog is the first of a two part series on regulated or “special access” for copper.  This discussion is particular to the US, especially regarding the breakup of the Bell System.  However, there are similar regulatory considerations worldwide, especially regarding shared access to new fiber facilities.

Before we get to the details of special access, it’s worth taking a look at how we got to the current situation.  For those who came in late (and as a reminder for the rest of us), let’s fire up the WABAC machine and revisit the composition and breakup of the original AT&T, along with the beginnings of the CLECs.

 

Notes from Ethernet Europe - Carrier Ethernet 2.0, SDN, NFV, Cloud Convergence

Apr 30, 2013 by Scott Knox

The theme of the recent Ethernet Europe 2013 - held in Frankfurt, Germany - was “SDN, CE2.0 and Cloud Convergence.”  In our busy, multi-tasking world, it seems the trend is to extend that frenzy to industry conferences as well.  This annual Light Reading conference was co-located with the MEF's quarterly face-to-face meeting.  Holding conference sessions on cloud convergence and CE2.0 in one session while right next door, the MEF technologists were hammering out the latest details of the next generation of specifications created an energetic vibe and opportunities to network during the breaks.  Nan Chen from the MEF provided good-natured jabs aimed at the hype surrounding Network Functions Virtualisation (NFV) and Software Defined Networking (SDN) before hinting at a forthcoming announcement from the MEF around cloud services.  In hallway discussions between sessions, the audiences seemed to agree that Chen's foreshadowing was focused on the MEF work on new Carrier Ethernet features designed to make it easier to implement and manage dynamic capacity services. 

Thinking Differently

Apr 22, 2013 by Prayson Pate

I recently started watching the “Downton Abbey” series, which takes place in the second decade of the twentieth century.  The characters are facing massive changes in their lives due to the rapid evolution of technology, including the growing presence of cars, phones and electricity.  Very quickly the characters will go from viewing these inventions as alien intrusions to being necessary parts of the infrastructure of daily life.  They will change how they think.

In previous blog entries I have covered some of the aspects of applying the cloud to the problem of telecom services.  In this segment I close the loop and talk about how we can apply the concepts previously discussed.  As with the characters in Downton Abbey, making this transition will require us to change how we think.

Good-day from Down Under – A CommsDay Summit 2013 Review

Apr 18, 2013 by Graeme Bellis

Overture hosted the refreshments once again at the annual CommsDay Summit held in Sydney, Australia April 9-10. This year’s event proved to be the largest to date, with over 400 delegates on hand.  I wanted to take the time to share some of my impressions and observations from this event.

The Value of Open

Apr 15, 2013 by Prayson Pate

In previous blog entries I discussed the value of cloud principles and tools.  A critical aspect of cloud development is the use of applications developed using open interfaces and standard protocols.
