Encore Networks has been granted a patent by the U.S. Patent and Trademarks Office under U.S. Patent Number 7,360,083. This patent relates to Encore’s method for providing security solutions to aid protocol acceleration over satellite networks using Selective Layer Encryption (SLE). SLE is an encryption technology that securely connects satellite networks with terrestrial links as part of an end-to-end Virtual Private Network (VPN) solution. The breakthrough architecture of SLE technology fully interoperates with all satellite modems from leading vendors. Unlike traditional VPN solutions, SLE supports optimal high-speed connectivity over TCP and UDP-based applications. Running IPsec based solutions over TCP accelerated satellite connections, as part of a site-to-site VPN solution, imposes an unacceptable throughput limitation on each connection. SLE overcomes this performance degradation and allows encryption and VPN capabilities at maximum link speed.
