Satellite networks are often severely bandwidth-constrained and possess high latency. Links may be as narrow as 64K and possess latencies of 250, 500, 750 milliseconds or more. This combination of conditions often leads to congested satellite connections and performance so poor that applications frequently time out. One can attempt to address the delays by improving TCP by increasing buffer sizes to acocmodate accomodate the long delays), modifying its congestion algorithm. One can also compress data and/or use streaming.
