The IP Multimedia Subsystem (IMS) is an emerging, standards-based architecture for deploying interactive voice and data services, quickly and efficiently, on a common network platform. The purpose of IMS is to leverage a single platform for a wide range of services – a platform that is both scalable and flexible from the start.

DNS, DHCP and ENUM are core services within the IMS platform. They must be capable of handling large traffic volumes, high service-level expectations, and constant change. Nominum’s carrier-grade IP naming and addressing solutions are uniquely able to meet these demands, with scalability, availability and flexibility that is unmatched in the industry.

Nominum provides the industry leading network naming and addressing solution for IMS. Nominum Foundation Caching Name Server (CNS), Authoritative Name Server (ANS), and Dynamic Configuration Server (DCS) offer core DNS and DHCP services for IMS networks. Nominum Navitas is a complete ENUM-based IP-application routing directory server that enables efficient inter/intra-carrier application level routing.  The Nominum solutions support successful IMS deployments by offering:

• Superior throughput and performance under load
• Open interfaces for flexible integration with provisioning and management systems
• Real-time configuration without downtime
• Unmatched scalability to manage hundreds of millions of DNS and ENUM records
• Reliable connectivity as devices register to the network
• Security against denial of service (DoS) and cache poisining attacks
