This paper I found, PDF relates to the routing of network packets through a satellite connection. This might be very interesting to a student of networking who is interested in satellite networking and the unavoidable latency issues that come with such a connection. With a 250ms latency, this would add on to any existing latency that existed, for example an online game and could make it unplayable. Even 350ms ping in a First Person Shooter game can be the difference between playing or missing out if everyone else has 30ms ping. And rubber banding is another annoying aspect. It is very annoying to see AI enemies that seem to teleport short distances when walking around. This makes them very frustrating to hit. But getting back to the satellites, this is a useful networking technology of course, but the latency cannot be avoided. This is just something you have to work with.
Below is a Youtube video showing an Internet speed test using satellite Internet. This shows that despite the latency, users of this service can get very fast speeds.
