SYSTEMS, METHODS, AND APPARATUS OF A SPACE COMMUNICATION FILE TRANSFER SYSTEM

Systems, methods and apparatus are provided through which in some embodiments a CFDP protocol state machine and state table is implemented on each of a number of entities in a space communication system. Some embodiments of the state table specify at least one action to specific events for each of a plurality of possible states and each state table implements a core CFDP protocol. In some embodiments a method to transfer data into and out of space flight systems and/or ground systems includes receiving a user request into a memory of a CFDP-compliant library apparatus. The method also includes starting a state machine in the memory of the CFDP-compliant library apparatus that prompts a core protocol to transfer a specified file to and/or from a specified destination and initiating transfer of data blocks from the memory of the library apparatus.
