In our multi-part blog series, we are examining how carriers can accelerate migration to next-gen services, increase service agility, mitigate signaling surges, and reduce operating costs.
In this week’s post, we look at the promise of NFV and caution carriers against choosing solutions that simply virtualize, and don’t reduce, complexity.
According to industry analyst firm Gartner, “The goal for NFV is to virtualize into software many network equipment types on to industry-standard servers, switches and storage to lower costs, improve efficiency and increase agility.” (“SDN and NFV Offer CSPs a New Way to Do Business;” May 3, 2013; G00248541; Akshay K Sharma and Akiyoshi Ishiwata)
What carrier doesn’t want to take advantage of these kinds of benefits?
Jumping on the NFV bandwagon replicating their physical hardware and software layouts into virtual environments does not achieve the benefits Gartner references. Virtualizing chaos to the cloud still results in chaos in the cloud.
We have a better approach. TITAN provides a common infrastructure for the virtual delivery of real-time signaling control, policy enforcement and database services. The result is a dramatic reduction in signaling between and within the voice, data and messaging networks, creating efficiency in communication. TITAN works with standard interfaces, allowing both combination and separation of applications as performance or operator requirements dictate.
Combining this efficiency with the elasticity benefits offered by cloud infrastructures, carriers are able to transition resources on demand for existing and new services. Load- and state-distribution techniques built into TITAN protect external network components from this elasticity, isolating changes and giving freedom to operators.
As the graphic shows, without having to buy, deploy and manage all those extra machines, a carrier can “lower costs, improve efficiency and increase agility.”
