EZchip Doubles the Price-Performance of 2.5-Gigabit Network Processors

Provides the NP-2/5, a 5Gbps duplex NPU with 10xGE ports and Traffic Manager

San Jose, Calif. – June 2, 2005 – EZchip Technologies (a subsidiary of LanOptics Ltd., NASDAQ:LNOP), a fabless semiconductor company providing high-speed network processors, is announcing its entry into the 2.5-Gigabit network processor (NPU) market. EZchip’s NP-2/5 is a scaled down version of the NP-2/10 10-Gigabit NPU and extends EZchip’s reach into lower speed segments of the Metro Ethernet market. The price of NP-2/5 is comparable to 2.5-Gigabit NPUs yet delivers twice the processing headroom and twice the number of Gigabit Ethernet ports. It is the only 5-Gigabit NPU in the marketplace featuring 5-Gigabit full-duplex throughput (i.e. 10-Gigabit total), integrated traffic management and ten 1-Gigabit Ethernet ports for 2:1 oversubscription. EZchip’s 5-Gigabit NP-2/5 and 10-Gigabit NP-2/10 are pin and software compatible and can be interchangeably assembled on the same board to build different product classes. The NP-2 will be on display at the SUPERCOMM show in Chicago at EZchip’s booth #85051 on June 7-9 and will sample to customers during June 2005.

By using NP-2/5 to power applications that typically employ 2.5-Gigabit NPUs, network equipment vendors gain important performance and cost advantages. Since the NP-2/5 is designed to deliver 5-Gigabit processing, it offers significant processing headroom for systems that require only 2.5-Gigabit throughput. The ten integrated Gigabit Ethernet ports provide the uplink redundancy and port density needed in new pizza box designs. Together with the 10-Gigabit NP-2/10, EZchip offers a single architecture scaling from 4xGE to 10xGE for high-density Metro Ethernet and Ethernet over SONET/SDH applications.

"The NP-2/5 strengthens EZchip's position and the 10Gbps leader is now also the Metro Ethernet technology leader," said Bob Wheeler, senior analyst at The Linley Group. "We believe the NP-2/5 offers the lowest system cost and power per GbE port of any store-and-forward NPU. With the addition of the NP-2/5, EZchip now offers the best solutions for multi-GbE through 10GbE Metro designs."

“According to The Linley Group, in 2004 the 2.5-Gigabit NPUs represented the largest segment of the NPU market while the 10-Gigabit NPUs represented the fastest growing segment and these two segments combined are expected to represent approximately two-thirds of the 2007 NPU market,” said Eli Fruchter, President and CEO of EZchip. “We are the only vendor to address both these market segments with the pin and software compatible NP-2/10 and NP-2/5. Our 20-Gigabit NP-2/20, currently in design, will further increase our total addressable market.”

About the NP-2 Network Processor Family

The NP-2 is EZchip's third generation family of network processors that builds on the architecture of the successful NP-1c and furthers its integration to include all the major line-card functions on a single chip. These include:

• 10-Gigabit (or 5-Gigabit) full-duplex processing
• Classification search engines
• Two 10-Gigabit (or 5-Gigabit) traffic managers
• Ten 1-Gigabit and one 10-Gigabit Ethernet MACs, and two SPI4.2 interfaces

The NP-2 is available in three models: NP-2/10, NP-2/10L and NP-2/5. All three models are pin and software compatible and can be interchangeably assembled on the same board to build different product classes.

The NP-2/10 provides 10-Gigabit full-duplex throughput (i.e. 20-Gigabit total) with integrated traffic managers, while the NP-2/10L is offered without the traffic managers. NP-2/5 provides 5-Gigabit full-duplex throughput (i.e. 10-Gigabit total) with integrated traffic managers. Typically, the NP-2/10 and NP-2/10L are employed in line cards and services cards while the NP-2/5 is used in pizza box applications.

Availability

NP-2 will sample to customers in June 2005.
