So you have got your network virtualized! What’s next?

Existing Skills Are Not Enough to Run Virtualized Networks

If it’s business as usual, we would move to operation phase and start reaping the virtualization benefits.

But here is a point. It is not just about implementing a technology like SDN or NFV; rather, it’s about the skills to run a network that is virtual, elastic and not hardware centric. Isn’t it quite different from the physical networks we traditionally deal with on a day-to-day basis?

And this point emerged strongly when I talked to multiple executives of Tier 1 and Tier 2 telcos recently about how they foresee the operation of their virtual networks in the future. In particular, what are their big concerns about operating the software-based networks?

Special-purpose networks, such as IP-VPNs, SD-WANs, and low-latency trading networks have been offered by CSPs for many years but engender large extra capex and opex costs. Re-imagining these networks as slices of a common network infrastructure promises to decrease the capex cost, but makes them more complex to plan, instantiate, and manage across the network domains. Moreover, the requirements of network slicing extend across every area of the network as well as network and business operations and the supporting OSS and BSS software systems. It will be a long journey. ACG Research is studying and following these journeys by the standards bodies, service providers, and vendors as they create the sliced network of the future.
