Networks to become NFV-readyNetwork meeting changing demands

The communications industry is undergoing an unprecedented level of change.

These changes have a profound impact on the operational aspects of virtual networks.

1. Hybrid

2.Real-time operation

3.Service agility

Existing processes and operational support systems (OSS) must adapt and evolve in order to become NFV-ready.
