Fast AcceleNet performance provides key differentiator from other DVB-S2 systems
April 2, 2009
ViaSat Inc. (NASDAQ: VSAT) customer Velconet S.A. has initiated an upgrade to the LinkStar®S2A system to increase bandwidth capacity, reduce networking costs, and provide faster network performance to 800 enterprise sites across Argentina. The new system includes DVB-S2 with Adaptive Coding and Modulation (ACM) and AcceleNet® compression and application accelerator software.
“The LinkStar S2-ACM network upgrade and implementation of AcceleNet software will produce long-term bandwidth savings and faster network performance that justify the investment in the new system,” said Juan Carlos Daidone, CEO of Velconet. “With these combined ViaSat technologies, satellite broadband is an excellent choice to serve future broadband needs in Latin America.”
The nationwide migration includes a new LinkStar ACM hub in Buenos Aires that implements significant bandwidth savings from industry standard DVB-S2 and ACM satellite technology. However, a key differentiator in the ViaSat satellite networking system is the addition of AcceleNet WAN optimization software, which combines a data compression engine and enterprise security with its patented transport optimization and a broad set of optional application accelerators. The AcceleNet software client detects and adjusts to network conditions and application protocols, in real time, for high performance over networks with limited bandwidth, transmission delay, and high packet loss, including 2G/3G wireless, DSL, and satellite.
“The bottom line for any network is to provide fast, economical delivery of the popular IP applications people need,” said Sergio Lastra, Andean Region sales manager for ViaSat. “That’s what we achieve by combining the benefits of the LinkStar S2-ACM system with our AcceleNet software.”
