CCSDS File Delivery Protocol

CCSDS File Delivery Protocol (CFDP) is a standard protocol used for reliable delivery of files between spacecraft and ground stations. It provides a set of procedures for the management of file transfers, including error detection and recovery, flow control, and congestion avoidance. CFDP is designed to operate in the harsh and noisy environment of space communications, where data corruption and loss are common. It is widely used by space agencies and commercial satellite operators for mission-critical data transfers. CFDP is specified by the Consultative Committee for Space Data Systems (CCSDS), an international organization that develops standards for space communications and data systems.
