Packeteer Launches Version 5.0 for Mentat SkyX Products; New release adds SCPS and XTP Congestion Control to Leading Protocol Acceleration Devices

CUPERTINO, Calif. -- Packeteer(R), Inc. (NASDAQ:PKTR), the pioneer and global leader in WAN Application Traffic Management, today announced the availability of SkyX(R) firmware version 5.0, adding SCPS protocol support and XTP congestion control to the industry's leading satellite link acceleration products. Recently acquired by Packeteer, Mentat(R) is the recognized leader in protocol acceleration technology.

The award-winning Mentat SkyX product line accelerates Internet Protocol performance when used over satellite and long delay wide-area network (WAN) links. By combining TCP protocol acceleration, Web acceleration, and data compression technologies, Mentat SkyX products increase download speeds and improve connection responsiveness while remaining entirely transparent to end users.

"SkyX version 5.0 provides a powerful set of options for our military customers and extends our leadership in acceleration," said Kay Guyer, Mentat General Manager. "SCPS now provides interoperability and we are continuing to extend XTP for maximum performance. With Packeteer visibility, QoS, compression and acceleration, this is the most comprehensive performance solution for all satellite and WAN links."

SkyX v5.0 adds SCPS-TP (Space Communications Protocol Standards Transport Protocol) as an alternative to XTP (Xpress Transport Protocol) as the transport protocol for the transmission of data over WAN links. SCPS is a military standard protocol, specified in MIL-STD-2045-44000 and CCSDS-714.0-B-1. Mentat SkyX users now have the option of selecting XTP for highest performance under the widest range of conditions or SCPS for interoperability with other SCPS-based acceleration products.

In addition to SCPS, SkyX v5.0 adds XTP congestion control to further optimize data transfers when using XTP over variable bandwidth conditions, including bandwidth-on-demand, full-mesh, and shared links. XTP congestion control automatically and dynamically adjusts the transmission rate to match changing bandwidth conditions.

Available immediately, SkyX version 5.0 is the latest firmware upgrade for the Mentat SkyX product line and is available free of charge to existing SkyX customers. The firmware can be downloaded from the Mentat SkyX website at www.mentat.com.
