[Satellite Today 11-24-08] UDcast has rolled out with WANcompress for its UDgateway security and performance solution, the company announced Nov. 24.
     UDgateway offers bandwidth optimization to reduce the high operating expenditure associated with satellite communications. WANcompress is a standard feature of version 4.1 for the UDgateway.
WANcompress is a software-based caching and data compression capability that works at the data stream level making it insensitive to applications. By maintaining large, synchronized caches at both ends of the link, WANcompress has the ability to recognize redundancy in the data being transmitted over the link even days or weeks after it has been sent for the first time. UDcast said that         WANcompress aims to use its local cache instead of transmitting data over the link whenever possible.
    The company said the new application can reduce the amount of data transferred over a satellite link by as much as 50 percent. WANcompress can be used in high cost, high delay or bandwidth constrained environments such as GPRS, UMTS or WiMax.
