Don't Miss Fiber Mountain Session Next Week in Vegas

August 5, 2014

Next week at Software Telco Congress (the NFV and SDN event) in Las Vegas - collocated with ITEXPO, there will be some amazing speakers who will help companies evolve into the software realm from hardware. Specifically, there will be one new speaker who has never spoken at a TMC event. M.H. Raza is the CEO of Fiber Mountain.

Why I'm Neutral on the Comcast, Time Warner Cable Deal

February 14, 2014


There has been lots of controversy over the merging of two of the largest cable companies Comcast and Time Warner Cable. Concerns range from fear of a monopoly to worse customer service to higher fees and data caps. Jim Edwards at Business Insider for example says you will get screwed if the merger goes through.

Consumers Union thinks if the merger happens, prices will increase and service will suffer.

Overture: Enabling Carriers to Compete Today

September 25, 2013

Communications service providers are facing unprecedented opportunity and threats and if the OTT threat wasn't a big enough challenge, its worth pointing out AT&T recently lost its bid to supply broadband to Starbucks to Google of all companies. Who would have thought this could even happen a mere five years ago?

I had a discussion about the pace of change in the CSP market with Mark Durrett of Overture and he went over many of the ways his company is helping carriers deal with the transition. The company is doing this through their Ensemble OSA product which is an open-architecture for software-defined services allowing service creation, activation and assurance by bringing many of the benefits of cloud computing to the metro edge.

Compass EOS and The Optical Approach to Core Routing

September 25, 2013

As core routers have to handle ever-faster data rates the high-speed connections suffer from a variety of problems as a result of challeenges which have to be overcome in inter-chip communications. Signal integrity becomes a problem over copper lines connecting ASICs as circut AC characteristics begin to dominate the impedance, inductance and conductance of the line and in-turn distort the signal. One way to mitigate these challenges is to utilize decision feedback equalization which consumes large amounts of power. Moreover, crosstalk has to be dealt with as electrical circuit speeds have reached the limits where traditional technology can overcome these effects.

Qwilt Speeds Video Downloads Worldwide

September 24, 2013

There are few constants in the world of technology - one of them has to be that there will never be enough bandwidth... Your connection can never keep up with the growing need of enterprises and consumers. Binge viewing especially has become a plague for carriers who are seeing their costs increase exponentially.

Enter Qwilt, the company that functions as a a virtual CDN-enabler for the last-mile through the use of appliances which run on COTS hardware and sit in the carrier network assisiting in caching in the important area between the core to aggregation to the edge to home.

Neustar Enables CSPS to Speed Their Carrier Ethernet Offerings

September 24, 2013

Neustar is one of the most amazing companies in the world of technology and telecom because they are involved in so many spaces and are responsible for allowing much of what we rely on to function correctly. In a recent conversation with Gary Zimmerman the head of marketing communications segment, he explained how Neustar is evolving into a an analytics company with its purchase of TARGUSinfo and others. Neustar is involved in short codes, SMS, Caller ID, LNP and more - they call themselves the neutral provider of real-time information and analytics to the communications services, financial services, retail, media and advertising sectors... Wow!

Optelian Lowers Packet Optical Service Roll Out Costs

September 24, 2013

SDN is a wonderful technology for networking but its a few layers up from packet optical service meaning you can't take advanatage of the latest in software defined networking innovation. In a conversation with Brian Pratt of Optelian, I had a chance to discuss how his company is trying to bring some of the best concepts in the SDN world to the packet optical world.

One of the main benefits of allowing software to manage the rollout and provisioning of packet optical service is you need less Ethernet engineers and WDM experts to deal with configuration and provisioning. The company sees this new world as being embodied by the concept of service-driven networking, a term which has the exact same acronym as software defined networking - on purpose.

Avaya Takes Networking Lead in SPB

May 15, 2013

At Interop Las Vegas 2013 Avaya was demonstrating their real-world Shortest Path Bridging (SPB) solutions and while interoperating with Spirent, HP and Alcatel-Lucent. Many of you will remember when Avaya was actually the enterprise division of Lucent before the company spun off just over twelve years ago. Randy Cross the company’s director of PLM discussed how there is a rapid move to software in the networking market and SPB is an evolution of MPLS allowing services to be created dynamically on the server where the applications reside or on the switches nearest the users.

This is one of the main benefits of SPB in-fact… It allows customers to simplify network creation and management by requiring service provisioning only at the edge of the network.

Ciena Launches New Services Play

February 25, 2013

Ciena has some exciting news when it comes to the world of service provider networks. We know the company as an equipment provider which has had years in the business but now they have branched out from not only upgrading networks but businesses. Chuck Kaplan VP Industry Marketing (pictured above) spent some time with me at Mobile World Congress 2013 explaining how his company has spent years helping customers not just spend money on their solutions but make it as well through a new consulting initiative.

The first step in the process is to redefine carrier services for a new world where data usage has tremendous spikes which are caused by things like cloud service utilization.

Thoughts on Alcatel-Lucent

February 8, 2013

One of the greatest challenges incumbent companies face is the ambivalence and corporate politics incumbency breeds and it only gets worse in what we call the age of acceleration where competitors arise faster and technologies shift more quickly than ever. Nortel, NSN and Alcatel-Lucent are all companies who enjoyed decades of leadership in the carrier market and in the process decided to provide generous benefits for their workers which would eventually help make them uncompetitive.

There is more to it - in the late nineties, Lucent acquired companies so quickly that its workers didn't know exactly who did what. Nortel too made a great deal of acquisitions.
