The communications industry is reshaping itself with next-generation services combining voice, data and video.  But triple-play services place new demands on core IP addressing infrastructure.  Broadband providers that add VoIP and IPTV without a significant upgrade of the DNS and DHCP infrastructure risk compromising the customer experience and increasing the cost of service delivery.  

DNS servers connect users to services on the network, while DHCP servers deliver network address and configuration information to computers, modems, VoIP phones and IPTV television converters.  REal-time provisioning of triple-play services requires highly flexible, configurable DHCP service that integrates with authentication and billing systems.  To meet subscriber expectations for service reliability, the DNS and DHCP infrastructure must be resilient to attacks, outages, and traffic spikes.

Nominum offers a suite of carrier-grade products that meet the demanding requirements of triple-play services.  Nominum's Foundation Caching Name Server (CNS), Authoritative Name Server (ANS), and Configuration Server (DCS) deliver:

• Real-time integration with authentication, billing, monitoring and other systems through open application programming interfaces (APIs)
  
• Reliable connectivity through resilient DHCP services that stay available regardless of load and slow or non-responsive network components
  
• Flexible lease assignments and deployment options to meet business and network requirements
  
• Simplified management and efficient software, reducing capital and operating expenditures
  
• Integrated failover that maintains service in case of the loss of a DHCP server
