Exhibit 99.1

IXIA TO BUY AGILENT TECHNOLOGIES’ N2X DATA NETWORK
TESTING PRODUCT LINE

Acquisition further extends Ixia’s market leadership in global converged IP network testing

CALABASAS, CA, October 21, 2009 — Ixia (Nasdaq: XXIA) announced today that it has signed a definitive agreement with Agilent Technologies, Inc. (NYSE: A) (“Agilent”), under which Ixia will acquire Agilent’s N2X Data Networks Product Line for $44 million in cash. Subject to customary closing conditions, the acquisition is scheduled to close on October 30, 2009 and will include certain assets of the N2X product line, along with its world-class customers, sales and R&D teams.

“This strategic and decisive move accelerates our growth, captures additional market share and positions Ixia to offer even greater value to our global customers and partners,” said Atul Bhatnagar, President and CEO of Ixia. “With our leadership position in high speed Ethernet (10/40/100 Gbps) IP testing, we will leverage the N2X products and customer base to further penetrate markets, particularly in EMEA and Asia.”

In addition to strong broadband and carrier access protocol expertise, the N2X is known in the industry for its intuitive and powerful user interface and excellent quality. Ixia is committed to enhancing, developing and supporting the N2X product line through 2015. To seamlessly support N2X customers, Ixia today also announced its Fusion initiative, which allows N2X owners to take immediate advantage of Ixia’s extreme scalability, higher speed Ethernet support, and layer 4-7 application testing. Details of the Fusion program are available at www.ixiacom.com/Fusion.

“This is an exciting day for Agilent N2X customers, partners and employees across the globe,” said David Churchill, Vice President and General Manager of Agilent’s Network and Digital Solutions Business Unit, Electronic Measurements Group, “N2X customers are accustomed to a strong tradition of easy-to-use test applications with extensive protocol support. Joining forces with Ixia will drive innovation and value across every aspect of the network testing marketplace.”

Ixia also announced today that its net revenues for the third quarter of 2009 will be approximately $46.4 million, compared to earlier guidance of $42 to $47 million. This revenue estimate includes a full quarter of results for Catapult Communications Corporation, which Ixia acquired in June of this year, but does not include any revenues related to its planned acquisition of Agilent’s N2X business.

Moelis & Company is acting as financial advisor and Bryan Cave LLP is acting as legal counsel to Ixia on this transaction.
