Virtual Domain Name System (DNS) Secures the Heart of Service Provider Networks - Updated for 2019




Download Report

Report Summary:

Domain Name System (DNS) has become a critical function in all Mobile Broadband Networks. As Mobile Network Operators (MNOs) and Communications Service Providers (CSPs) move to Network Function Virtualization (NFV) and Software Defined Networking (SDN), scalable and reliable service discovery is paramount for business operation.

Evolving DNS from a utility appliance to a scalable and secure virtualized platform ensures secure, and agile control for managing service selection.

Service Providers can now utilize powerful Virtual DNS to secure and grow profitable subscriber services in next generation networks that demand unique capabilities not available on legacy DNS platforms.
