Neither this Recommendation nor any ensuing standard is a substitute for a memorandum of agreement. No later than five years from its date of issuance, this Recommendation will be reviewed by the CCSDS to determine whether it should: (1) remain in effect without change; (2) be changed to reflect the impact of new technologies, new requirements, or new directions; or, (3) be retired or canceled. In those instances when a new version of a Recommendation is issued, existing CCSDS-related Agency standards and implementations are not negated or deemed to be non-CCSDS compatible. It is the responsibility of each Agency to determine when such standards or implementations are to be modified. Each Agency is, however, strongly encouraged to direct planning for its new standards and implementations towards the later version of the Recommendation.

This Recommendation specifies a communications protocol to be used by space missions to transfer space application data over space-to-ground or space-to-space communications links. This Recommendation is developed from the specifications of the Data Link Layer portion of older CCSDS Recommendations (references [B2] and [B3]), which define essentially the same protocol and services but in a slightly different context. This Recommend...
