The innovation is a software library that supports reliable transfer of large data blocks to and from spacecraft (these transfers are called "loads and "dumps"). The software library implements the core CFDP protocol (an intermational space standard developed to accomplish reliable loads and dumps), while providing the flexibilty required to be suitable for both flight and ground software, and reusable from mission to mission.Objective was to produce generic software that can accomplish both loads and dumps, it is suitable for both flight and ground environments, and reusable from mission to mission. Loads and dumps use fundamental communication capabilities provided by a space link. Most missions use the CCSDS space link protocol, but not all. Some space links are based on the Internet protocols, and there is some support for migrating in that direction. To be widely reusable, a solution must flexible with regard to space link. CCSDS File Delivery Protocol (CFDP) was developed specifically to provide a standard way of accomplishing loads and dumps. CFDP fully implements the core CFDP protocol without constraining the underlying space link and data storage system. Two main tasks to be accomplished are sending and receiving data blocks ("files").
