Ixia's IxTriplePlay Toolset Contributes Significantly to Successful Moonv6 Network Test Event; IxChariot Provides IPv6 Performance Assessment in Multi-Vendor VoIP, Network Management, and Security (IPsec) Protocol Interoperability Event.

CALABASAS, Calif. -- Ixia (Nasdaq: XXIA), a leading, global provider of IP performance testing solutions, announced today its successful participation in IPv6 interoperability tests conducted by the University of New Hampshire InterOperability Laboratory (UNH-IOL) on the Moonv6 network, the world's largest multi-vendor IPv6 network. During the five-week testing period, which began Oct. 28 and concluded Dec. 2, the IxTriplePlay(TM) toolset was used to validate network performance and device interoperability running voice, video, and data traffic over an IPv6 network infrastructure.

Ixia's IxChariot(R), the flagship test application in the IxTriplePlay toolset, was used to verify a wide range of performance metrics by emulating stateful Layer 4 through 7 application traffic. IxChariot is fully IPv6 capable, which makes it an ideal test tool for analyzing and validating real-world traffic across IPv6-enabled networks. Additionally, Ixia's IxExplorer(R) test solution provided an easy-to-use framework for executing a variety of IP routing protocol emulations, including DHCP over IPv6, uniquely supported by Ixia.

"Ixia is delighted to have been a part of the Moonv6 interoperability event for three years in a row," said Dr. Diego Dugatkin, Ixia's Principal Technologist and Director of Ixia University. "Our participation this year presented true Triple Play testing over IPv6 using IxChariot in combination with Ixia's IxExplorer test tool to validate performance of DHCP over IPv6. The unique scalability, flexibility, and power of these tools provided a realistic environment to accurately verify multi-vendor interoperability."

"Ixia has been a long standing supporter of the Moonv6 test events," said Ben Schultz, IPv6 Managing Engineer for UNH-IOL. "With the dynamic and quickly changing environment of Moonv6, the flexibility of Ixia's software and support is highly appreciated. This has significantly contributed to the success of the Moonv6 interoperability demonstration."

The U.S. Defense Information Systems Agency's Joint Interoperability Testing Command (DISA JITC) performed the majority of the IPv6 testing from the army's Fort Huachuca, Arizona JITC base. A North American IPv6 Task Force project, Moonv6 has focused the cooperation of the UNH-IOL, Internet2, various U.S. government agencies, technology organizations, networking equipment companies, and service providers.

"JITC is more than just an 'IPv6 bumper sticker,'" said Captain Jeremy Duncan, JITC Action Officer. "We are providing real and useable results to the DoD community on the maturity and feasibility of IPv6. We saw real progress made in RFC compliance for IPv6."

The second Moonv6 test of 2005 included an application demonstration using commercial VoIP-over-IPv6 software. In addition, the test included mobility demonstrations and interoperability testing between firewalls, hosts, and routers using the IPsec security protocol.
