Virtual Private Network (VPN) is an encrypted connection that enables remote clients or mobile workers to securely connect with a private network over the public Internet. VPN connection gives employees secured access to their company networks. The use of VPN connections can increase safety and security in the maritime industry. These connections can allow maritime administrators to send mission-critical information from their land-based shore locations to ships docked in other part of the world.
Use of VPN over Satellite Internet connections
Previously, satellite Internet services offered less bandwidth that was required for VPN connection. Geosynchronous satellites used to take long time to transmit data between the satellite and ground stations, which is called high latency. With the invention of mobile satellite services such as maritime VSAT systems, VPN can now function properly over broadband satellite used by ships.
• The low latency of VSAT networks makes it practical to implement VPN connections across the shipping industry.
• Satellite Internet interacts with many elements of Transmission Control Protocol (TCP) such as congestion avoidance algorithms and data acknowledgment mechanism. These limitations can be overcome by using TCP Acceleration process with indoor units (IDU) or VSAT equipment designed for satellite.
• VSAT Systems offers two 3-Key Triple Data Encryption Algorithm (3DES) alternatives that encrypt the data that you want to send, leaving the Internet Protocol (IP) and TCP headers accessible. Since the headers are now available, the encrypted packets are compatible with all types of satellite modems or broadband satellite services used by ships.
VSAT mobile satellite services are friendly with many VPN solutions. No need to make a trade-off between functionality and security of your secured networks. You can use your current VPN solution with mobile broadband satellite services and VSAT equipment to increased latency of the network and VPN performance. Ship operators in remote locations require access to their business critical applications and industrial grade security while communicating over satellite Internet. Everything becomes possible when you merge VPN solutions with VSAT mobile satellite service for your maritime operations.
