Exhibit 99.1

IXIA COMPLETES ACQUISITION OF ANUE SYSTEMS, INC.

Network Visibility Solutions Extend Ixia’s Reach into Production Networks

CALABASAS, CA, June 4, 2012 – Ixia (NASDAQ: XXIA), a leading, global provider of converged IP and wireless network test solutions, announced today that it has completed the previously announced acquisition of Anue Systems, Inc. (“Anue”), a leading developer of network visibility solutions.

“This strategic move extends Ixia’s leadership in validating next-generation networks and applications running over wireless access infrastructure, cloud environments, and converged data centers,” said Vic Alston, Ixia’s president and chief executive officer. “Anue’s solutions provide visibility into network traffic in real-time, enabling network operators and enterprises to quickly and effectively allocate resources for new services, new users, and new traffic patterns. This insight into network performance, scale, and resiliency allows network operators to ensure a higher quality of experience across their production networks.”

As applications increasingly run in large data centers and across mobile networks, service providers and large enterprises need better visibility into application performance. Traditional monitoring solutions cannot achieve the scale necessary to effectively handle the number of ports, high speeds, and increasing amount of traffic that needs to be analyzed.

Network visibility is quickly becoming an essential component of any network architecture design. It allows network managers to maximize the use of monitoring and analysis tools, and gives them otherwise unavailable visibility into how applications are performing. The combination of pre-deployment testing/validation with post-deployment monitoring of security, network services, and application performance provides a more complete solution to optimize and secure today’s data centers and networks.

Anue’s Net Tool Optimizer solution connects data center and cloud environments to network analysis tools, allowing network engineers to aggregate traffic from multiple network elements and optimally filter the traffic monitored by each analysis tool. With the Anue Net Tool Optimizer solution, IT resources are maximized, network troubleshooting is streamlined, and network monitoring capacity is expanded. Anue’s technology platform, coupled with Ixia’s strong market position, will create significant opportunity for Ixia to lead in the rapidly growing network visibility market.
