Expand Networks Provides a Complete WAN Optimization Solution for DISA

By Raju Shanbhag, TMCnet Contributor

Expand Networks (News - Alert), a provider of application acceleration solutions over the Wide Area Network (WAN), has announced that it has replaced Packeteer’s (recently acquired by BlueCoat) Performance Enhancing Proxy (PEP) for Defense Information Systems Agency (DISA)’s DVB-RCS Network. The company was able to replace Packeteer (News - Alert) due to its ability to provide a complete WAN optimization solution, rather than a TCP Acceleration only solution for the DVB-RCS VSAT network.

DISA provides real-time IT and communications support to the President of the United States, Vice President, Secretary of Defense, the military services, and the combatant commands. DISA’s ability to fulfill its mission and support the national security community is considerably improved by Expand Networks’ PEP+ accelerator solution.
Expand’s Performance Enhancing Proxy (PEP) advances SCPS (Space Communications Protocol Standard) TCP Acceleration mitigate the effects of latency over satellite communications. The PEP uses services such as best-in-class Layer 7 QoS, patented byte-level caching and compression, as well as secure monitoring and management capabilities to achieve its purpose. To replace Packeteer’s SkyX Gateways, Expand’s WAN Accelerators were chosen by DISA over those from Comtech and XipLink (News - Alert).
In the near future, Expand’s Accelerators will likely be used to improve the capabilities of the DVB-RCS network by supporting a telemedicine initiative for military medical personnel deployed in the Middle East. They also accelerate the two-way, real-time IP services on the DVB-RCS network. Between remote medical facilities and large hospitals across the world, Expand’s accelerators will ensure quick and reliable transmission of important medical data, such as X-rays, MRI, and other radiological imagery studies.
Recently, the company also announced the Expand Accelerator 1610 which provides the Accelerator technology in a PC-104+ condensed form factor. The 1610 is a perfect solution for space constrained and rough environments, says the company.
“This is a very significant win in the Satellite Communications marketplace,” said Howard Teicher, Expand Network’s vice president for Public Sector & Satellite Markets. “While we have worked with DISA in the past, and have a long history of success with various government agencies, DISA’s is the primary Defense Department telecommunications service provider. The selection of Expand highlights our key competitive differentiators and ability to provide the features that other companies simply don’t have.”
