Virtual Domain Name System (DNS) Secures the Heart of Service Provider Networks

Report Summary:

Service Providers need NFV to reduce CAPEX and OPEX as traffic escalates. So far Mobile Network Operators (MNOs) and Communications Service Providers (CSPs) have focused on their Data Centers and Telecommunications Infrastructure for NFV and SDN savings.

But their IP Infrastructure offers additional major opportunities for virtualization benefits especially - the Domain Name System (DNS) - a critical IP Control Plane capability - that supports scaling for applications requests and security threat management. IP Address management (IPAM) is essential for dynamic assignment of network resources.

DNS also provides critical real time mapping of application name/domain requests and the IP addresses of the resources they are requesting. DNS is therefore well positioned to evolve from a utility appliance to a virtualized platform that guarantees secure, scalable services with automated control, monitoring and management of IP address spaces and service gateways.

This report describes how Service providers can leverage Virtual Secure DNS (vSDNS) to ensure reliable secure performance and scalability. For more industry discussion you may register at http://bit.ly/1Vzay6t to hear the related Webinar.
