Nominum Delivers ENUM for IMS with BladeCenter

Nominum is leveraging IBM's eServer BladeCenter to deliver ENUM carrier grade scalability for service Providers delivering IP Multimedia Subsystems (IMS). Using Nominum's ENUM solution running on seven IBM eServer BladeCenter systems in a single BladeCenter chassis, the combined solution was able to load more than 200 million NAPTR records and respond to over 250,000 queries per second with a response time of 1 millisecond per query. By comparison, open source solutions including BIND, DJBDNS, and PowerDNS failed during their attempt to scale past 50 million records.

Leveraging Nominum's ENUM solution, IBM adds industry leading ENUM server performance and availability for IP-based services to its extensive list of IP Multimedia Subsystems (IMS) capabilities.

"The complexity of today's networks is requiring a fundamental shift to reliance on software and services to drive next generation networks," said Jim Pertzborn, vice president Telecommunications Industry, IBM Systems and Technology Group. "Our relationship with Nominum strengthens our capabilities in delivering carrier-class infrastructure to enable our customers IMS strategy."http://www.nominum.com
