Ixia, IKOS, IP Infusion and OSE Systems Join for Worldwide Seminar Series on Communications System Design

Solutions to Accelerate Time-to-Market for Developers of Communication Chips, Protocols, Systems, and Software

Calabasas, CA, April 17, 2002 - Ixia (Nasdaq: XXIA), a leading provider of high-speed, multiport network performance analysis and network optimization systems announced today a joint seminar tour with IKOS, IP Infusion and OSE Systems. This worldwide seminar will cover 10 cities over six weeks, beginning April 16th.

"Ixia is happy to participate in this seminar series to demonstrate how it's performance and conformance analysis solutions are designed as flexible tools for a wide variety of analysis applications", said, Eran Karoly, vice president of marketing for Ixia. "This seminar will demonstrate the importance of sophisticated analysis solutions as well as emulation tools, off-the-shelf operating systems and protocols in accelerating time-to market of communication systems design."

Offered at no cost, the seminar program will feature a wide range of sessions, all of which are focused on enabling faster and more reliable system deployment. The seminar topics include: Ixia's wide range of performance analysis solutions for Ethernet, 10 Gigabit Ethernet, and Layer 4 through 7 content aware switching as well as performance and conformance testing; IP Infusion tools for accelerating the development cycle by utilizing COTS (Common off-the-shelf) development tools for protocol implementations; IKOS' emulator technology which can raise the abstraction level and increase the productivity of test-bench methodologies through advanced test bench modeling techniques; and OSE Systems powerful platform for the design of real-time embedded systems, including the OSE Real-Time Operating System (RTOS) and system level analysis tools for building heterogeneous, high availability, and fault tolerant applications, to satisfy the requirements of today's complex systems.

"This seminar series will arm hardware, embedded systems, and software developers with the knowledge they need to get their communication systems designs to market more quickly," said Gary Hemminger, vice president of marketing for IP Infusion. "We are pleased to be collaborating with Ixia, IKOS, and OSE Systems to enable our customers to take full advantage of our companies respective development, verification, and validation solutions."

"OSE Systems is excited to have this opportunity to show our complementary strengths in the areas of RTOS simulation, application development, and software testing and analysis of multiple CPU and DSP fault-tolerant real-time designs as an integral part of the total solution provided by Ixia, Ikos, IP Infusion, and OSE Systems."

"IKOS Systems is also excited to participate in this joint seminar series with Ixia, IKOS, IP Infusion and OSE Systems. IKOS and Ixia are both leaders in our respective fields, together we are providing best-in-class solutions for our common customers," according to Juergen Jaeger, IKOS Systems, Director Channel Marketing. "The purpose of the seminar is to give attendees a unique opportunity to get the latest information on state-of-the-art design and verification tools for communication and networking design."

This 10 city tour begins in Dallas, TX on April 16th, then continues to San Jose, April 18th; Ottawa, Canada, April 23rd; Boston, MA, April 25th; RTP, NC April 30th. In May, the seminar series heads to Europe in Helsinki, Finland, May 14th; Munich, Germany, May 16th; and then to the Asia-Pacific region with Tokyo, Japan, May 21st; Seoul, Korea, May 23rd, and Hsincchu, Taiwan, on May 28th.

Expected to attend this complimentary seminar will be today's designers, software developers and hardware engineers that require rapid and precise system development tools. These systems architects and communications equipment designers are developing embedded communication protocols, designing network software and developing network elements.
