Riverbed’s approach accelerates all TCP applications that are transmitted via Satellite connections or WAN connections. Most applications can take advantage of the underlying Riverbed technologies to achieve significant, immediate acceleration. Some applications are optimized dramatically (FTP) with no additional Application Streamlining modules. Other key applications are so important that Riverbed has implemented application-specific optimizations to achieve the performance enhancements that customers are looking for. Riverbed continues to add Application Streamlining modules for additional applications. Templates allow customers to implement modifications for in-house web-based applications. © 2006 RIVERBED TECHNOLOGY, INC – CONFIDENTIAL
