THE CCSDS FILE DELIVERY PROTOCOL (CFDP)In recent years, CCSDS has concentrated on providing flexible and efficient transfer protocols for various data over space links.The basic CCSDS suite solves the data transfer problems for current missions in which the manipulation of onboard storage tends to be handled manually, or by ad hoc protocols developed privately.While this is an acceptable way of managing a limited amount of memory, with the rapid development and take-up of solid state mass memory this is no longer the case.The availability of gigabytes of solid state memory leads to a new era of spacecraft operation, where much of the routine traffic to and from the spacecraft will be in the form of files.Furthermore, due to the random access nature of the onboard storage medium, it becomes possible to repeat transmission of data lost on the link and thus guarantee delivery of critical information.
