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.
• The Census Bureau’s data shows fewer telecom companies and fewer employees in the industry in 2013 than in 2008.
• Over this five-year period, the industry’s gross receipts increased nearly 15 percent, while cumulative payroll decreased 2.25 percent.
• Compared to other industries, telecom experienced above-average growth. This growth was driven largely by the mobile and wireless sector.
I found the first two points on industry consolidation to be very interesting. The author Craig Borowski told me:
"The digital age has brought more change to telecom than almost any other industry. With above-average growth from 2008 to 2013, I was surprised to see that the Census Bureau’s data was showing a decrease in both the number of telecom companies and employees. Although mergers in telecom are not a rare occurrence, the extent and acceleration of convergence in the industry is eye opening."
Craig’s report notes the importance of efficiency in this transformation.
One of the factors driving increased efficiency in telecom is convergence, defined as “the efficient coexistence of telephone, video and data communication within a single network.” Eliminating the prior need to develop and maintain independent networks is allowing the telecommunications industry to operate with lower overhead and higher margins.
We can see that there has already been a focus on cost cutting and efficiency, even before SDN and NFV became hot. How much more can these new technologies contribute?
In addition, if you only looked at the first two key findings above you would say that the CSPs had done a pretty good job of not only cutting costs but also in growing revenue. However, the third key finding reveals the fly in the ointment: there was little growth in the wireline sector. From the standpoint of revenue and spending the problem is even worse that it might at first appear. That’s because the growth in mobile and wireless creates even more load on the wireline network.
The growing pressure on the wireline network is reflected in CSP spending. Ray Mota of ACG Research reports that:
The Total Worldwide Service Provider Carrier Router-Switch market is projected to increase from $11.9 B to $15.4 B by 2018 (CAGR 5.3%). From a regional perspective, the Americas and APAC will lead the growth as carriers respond to increases in data traffic, Big Data, virtualization, software-defined networking and the unrelenting demand for innovative and intelligent applications and services.
This anticipated growth in spending on edge equipment underscores the need to broaden the applicability of SDN and NFV beyond the much-discussed increases in efficiency. The drive must be towards creating an infrastructure that supports creating innovative new services – especially those that we haven’t yet thought of.
