===Reducing satellite latency===
Much of the slowdown associated with satellite Internet is that for each request, many roundtrips must be completed before any useful data can be received by the requester.{{efn|TCP is bound by the low latency of a three-way handshake. See [[TCP handshake|Transmission Control Protocol]].}} Special IP stacks and proxies can also reduce [[Latency (engineering)|latency]] through lessening the number of roundtrips, or simplifying and reducing the length of protocol headers. Optimization technologies include [[TCP acceleration]], [[Hypertext Transfer Protocol|HTTP]] pre-fetching and [[Domain Name System|DNS]] caching among many others. See the [[Space Communications Protocol Specifications]] standard (SCPS), developed by NASA and adopted widely by commercial and military equipment and software providers in the market space.
