Issues and Solutions When Deploying VPNs over Satellite Links

This paper summarises the issues created when deploying a virtual private network in broadband satellite systems. These issues are related to protocol enhancing, overhead, fragmentation, mobility, quality of service and network address translation. Solutions for these issues are proposed from the point of view of the satellite operator, since most depend on what degree of control it has over the network. More specifically, this paper explains which solutions can be applied when the satellite links an airplane with the ground.
