VPN over Satellite

Virtual Private Networks (VPNs) consist of two or more computers or networks of computers that communicate securely with each other across an unsecured or public network such as the Internet. VPNs are established by using compatible encryption and decryption hardware or software at each end of the connection. Because the VPN network exists inside the larger network of the public Internet, it is often referred to as a “tunnel”.

For various reasons, there is a constantly growing requirement from the business and government sectors to provide secure broadband data connections to their remote locations, including employee residences.

While DSL and Cable Internet are clearly the most cost effective solutions, DSL and cable do not reach approximately one-third of the remote locations that seek broadband service.

Two-way satellite Internet service is fast and reliable. It works very well for browsing, email, and most other Internet applications. The increasing need for broadband services combined with very affordable solutions is driving demand for satellite services across North America. However, VPN has typically had a much lower performance (>70% degradation) than traditional web browsing or email over the same satellite link primarily due to latency.

Any encryption technique over any connection imposes some performance loss. Performance also suffers as a function of increased latency. Some of the geosynchronous satellite services available today, such as VSAT Systems, have sufficiently low latencies (under 650ms) that even an IPsec VPN becomes practical.
