Service Management in the Brave, New, and Virtualized World

Aug 15, 2014 by Ramesh Nagarajan

Ramesh NagarajanThese are exciting times in the world of Network Functions Virtualization (NFV). NFV fever has truly gripped the market and NFV-washing is fully underway. However, there is real progress underneath and beyond the hype.  Operators are beginning to seriously contemplate commercial deployments of NFV, and are devoting considerable effort to the important topic of NFV service management. Network operations teams at the service providers have been asking the difficult questions of how to manage all of the virtual stuff compared to the physical, custom built appliances they have operated in the past.

“SDN” and “NFV” are on the tips of everyone’s tongues these days. With so much buzz  and confusion, we wanted to get the straight scoop from those who are closest to the action – our team of in-house experts who help Overture’s customers to successfully navigate these evolving technology developments on a daily basis.

Fiber is the clear choice for delivering innovative high-speed services at the edge of the network, and the amount of deployed fiber continues to grow.  However, the availability of business access to fiber remains relatively low and even lower for residential areas.  In both cases, the cost of new fiber construction is high.  How do we close the gap between the need for high speed access and the limitations of deploying fiber?

Cost Cutting is Not Enough

One of the big drivers for Software Defined Networking (SDN) and Network Functions Virtualization (NFV) is reducing CapEx and OpEx.  While attractive and perhaps necessary, cost cutting is not enough to take Communications Service Providers (CSPs) forward.  They need the ability to rapidly develop new wireline services that will drive revenue growth.

Follow the Money – How Use Cases Drive Innovation

I have previously written about how successful innovation is driven by three factors:

  • A customer problem or opportunity
  • Domain knowledge
  • Advances in technology

This blog will dig deeper into the first item: a customer problem or opportunity.  Why is that critical to innovation?  Because that’s what people will pay for.  Here we explore the two categories of real world use cases that represent important elements on any company’s balance sheet: saving money and making money.

I recently had a chat with Russell Fleischer, CEO of HighJump Software, which is a provider of supply chain management software.  HighJump started with traditional onsite approach to software solutions, but has since moved to the cloud.  HighJump’s Chuck Fuerst describes some of the “Benefits Of Cloud In Logistics” in the December 2013 issues of CIO Review, including flexibility, pay-as-you-go, TCO, incremental features and security.  I asked Russell Fleischer about how HighJump uses the cloud to deliver these benefits.  This blog will describe his thoughts, and will also suggest that the lessons learned by HighJump also apply to Communications Service Providers (CSPs).

 

Accelerating Wholesale Carrier Ethernet: 4 Success Factors

Mar 24, 2014 by Mark Durrett

Note: this article originally appeared in the Comptel Plus Show Daily, March 18, 2014.

As Ethernet services have grown in popularity, communications service providers (CSPs) are coming to terms with the fact that, in order to deliver this popular offering to multi-site enterprise customers, they must partner with other operators to expand their service footprint and reach.  This has resulted in a red-hot wholesale market for Carrier Ethernet which has surpassed Frost & Sullivan’s predicted growth rates with rising demand for Ethernet both for mobile backhaul (tower/cell site access) and aggregation. Heavy Reading expects this trend to continue into the foreseeable future.
