Expand Extends Leadership In Assuring Citrix Performance With New Product Functionality

Intelligent Data Analysis Feature in Expand ACCELERATORs Enhances Support for Citrix MetaFrame .

ROSELAND, N.J., February 14, 2002 -- Expand Networks, a leader in the field of bandwidth optimization technology, today announced the general availability of a new feature in the company's award-winning ACCELERATOR product-line. The new Intelligent Data Analysis (IDA) feature utilizes network resources more efficiently in LAN-based ACCELERATOR deployments and delivers improved acceleration results for Citrix-hosted applications.

Citrix Metaframe users repeatedly access the same content from the network. The ACCELERATORs IDA feature enhances support for Citrix MetaFrame applications because, through the use of statistical multiplexing, IDA allows more Metaframe data to traverse the WAN. IDA achieves this increase in throughput by:

·   Consolidating Citrix header data in pure IP implementations - IP header represents significant overhead in small packets generated by Citrix. It constitutes almost 30% of the Citrix packet. IDA removes repeat header information and sends this data only once across the network.
·   Consolidating Citrix payload in all environments - IDA extracts data from small packets originating from different Citrix MetaFrame users, and sends packets optimized for specific WAN conditions. IDA eliminates all redundant data transmissions across the WAN.
·   Controlling latency and jitter -IDA reduces latency and jitter, especially over slow WAN links that are commonly used for Citrix Metaframe deployments.

The end-result is better, more consistent Citrix performance; and support of up to four times more Citrix users on the existing infrastructure.

Expand Networks is proving its leadership in assuring the performance of critical applications," said Neal Goldman, director, Application Infrastructure & Software Platforms, Yankee Group. The ACCELERATORs Intelligent Data Analysis is now the third product feature that Expand has developed as part of the companys ongoing commitment to support enterprise application performance. The other two features -- drop recovery code and flow control are targeted at preserving data integrity."

The ACCELERATORs are built on Expands patented Enterprise Caching Technology. Enterprise Caching is an application-independent technology that focuses on increasing network capacity available to all enterprise applications: IP, non-IP, web, and non-web. The ACCELERATORs are deployed in over 150 customers worldwide, and operate on all network traffic on both ends of the Wide Area Network (WAN) - central as well as remote sites. They remove repeat data patterns from the network with important bandwidth savings. The end result is an increase in network capacity, throughput and speed of 100 to 400+ percent, which ultimately translates to average payback periods of 6 - 12 months.

Many of our customers use Citrix to run their organizations, such as large IT shops like NTT Communications, the US Veterans Administration and Fairmont Supply," said Talmon Marco, president and co-founder, Expand Networks. It is therefore imperative that we continue investing in extending the ACCELERATORs leadership in improving Citrix performance."

The new Intelligent Data Analysis feature is now available in all Expand ACCELERATOR products.
