Space Communications Protocol Specifications

• —A set of extensions to FTP to make it more bit efficient and to add advanced features such as record update within a file and integrity checking on file transfers.
• —A set of TCP options and sender-side modifications to improve TCP performance in stressed environments including long delays, high bit error rates, and significant asymmetries. The SCPS-TP options are TCP options registered with the Internet Assigned Numbers Authority and hence SCPS-TP is compatible with other well-behaved TCP implementations.
• —A security protocol comparable to IPsec
• —A bit-efficient network protocol analogous to but not interoperable with IP
