Both acceleration and optimization technologies help overcome
satellite latency to varying degrees. Due to the nature of TCP
transmissions, any performance increases achieved by the various
acceleration methods are offset by serious compromises in data
security. Fundamental incompatibilities arise when one attempts to
operate conventional VPN devices over satellite links, due to the
nature of TCP acceleration techniques commonly used for broadband
satellite connections. VPNs may not function at all, security is
compromised through the use of transport mode VPNs, and/or the lack of
TCP acceleration can degrade application performance over satellite
links so as to be unusable. Apart from this reduced security, most
acceleration technologies enhance only certain types of applications
(large file transfers, video).
