Scope

This document specifies the transmission architecture of the File Transfer Protocol (CFDP) using encapsulated packet protocols in space-to-ground, ground-to-space, and space-to-space communications. It also describes the lower-layer services of the CFDP protocol and the encapsulated packet protocols that cooperate with the CFDP protocol.
This document is applicable to the system design that uses encapsulated packet protocols to carry the CFDP protocol.
