Why does the service slow down when used in conjunction with a VPN?
HughesNet uses sophisticated acceleration techniques to enable high-speed performance over satellite. These acceleration techniques require access to data packet header information, which is blocked when IPSec-based VPNs are used. These VPNs encrypt the data and create a secure tunnel through the HughesNet network.
Without consideration for the latency introduced by the path delay to geosynchronous communications satellites (in orbit above the earths equator at an altitude of 22,300 miles), high-speed Internet transmission would be difficult. Satellite service providers do however offer high-performance Internet access over satellites (like DIRECWAY) using sophisticated TCP/IP protocol processing and data acceleration algorithms. An IPSEC/VPN secure encrypted connection (IPSEC is the most widely used VPN technology in use) encapsulates the TCP/IP data (called tunneling) which renders useless these performance enhancement techniques. Hence the users speed is degraded. Secure network architectures using satellite access requires a disciplined implementation and close coordination between the service provider and the corporate network customer.
