Scope of Activity

The Working Group will produce a CCSDS Protocol Profile for operating CFDP over the CCSDS Encapsulation Service. This protocol profile will run above the Encapsulation Service; this document will be Magenta and no interoperability testing will be done.

Rationale for Activity

The CCSDS File Delivery Protocol (CFDP) has been defined as an interoperable method for transferring and manipulating files. To achieve interoperability at typical cross support points (e.g. earth to spacecraft or spacecraft to spacecraft), in addition to agreement on the use and configuration of CFDP, consensus must be reached on adoption of the complete set of underlying protocols which provide the bearer service(s) for CFDP. Within these underlying protocols there is scope for adopting various options which, if not down-selected, can result in a failure to interoperate. There is, therefore a need to profile the use of CFDP and its underlying CCSDS bearer protocols to minimize the amount of mission specific negotiation required to produce a cross support agreement.

Goals

The Working Group will produce a CCSDS Protocol Profile for operating CFDP over the CCSDS Encapsulation Service. This protocol profile will run above the Encapsulation Service; this document will be Magenta and no interoperability testing will be done.

Survey of Similar Standards Efforts Undertaken in
Other Bodies and elsewhere in CCSDS

This work will leverage the work of other CCSDS groups, including the CFDP working group and the space link services area.

Patent Licensing Applicability for Future Standards

None known.
 

Technical Risk Mitigation Strategy

CFDP and underlying protocols are mature, well understood and have been interoperability tested and deployed in missions. The down-selection of options may conflict with some deployed implementations but this has been anticipated and inter-agency informal agreements have been reached to use packet services as the bearer for CFDP in all cases.

Management Risk Mitigation Strategy

Unavailability of resources could delay achievement of milestones. Fallback option would be to reschedule the milestones or terminate the work.
