Scope of Activity
The purpose of this WG is to clearly define how IP datagrams will be carried over CCSDS links, including compressed header IP datagrams. This activity is envisioned to encompass three major areas: IP over CCSDS links service concept, PDU formats, and transfer service primitives.
Rationale for Activity
It is generally recognized that IP datagram transfers will become more prevalent for both on-board applications as well as off-board for transfer through a network of in-space CCSDS data links. Although the CCSDS space link protocols can support IP datagram transfer, there is a lack of a clear specification for how to accomplish this. -. Currently, each of the four CCSDS space data link protocols - AOS, TC, TM, Proximity-1 - includes a short section (devoid of any context information) that defines how to carry IP datagrams over that link. This Working Group Charter establishes the detailed steps, personnel, and schedule needed to transform the ‘IP over CCSDS Links BOF’ White Paper into a formal CCSDS specification that will become the agreed international mechanism for interoperably transferring IP datagrams over CCSDS space links, to ensure cross-support amongst space Agencies requiring this capability.
Goals
The IP over CCSDS Space Links WG will have the following objectives: 1) Describe the recommended method(s) of transferring IPv4, IPv6 and compressed IP header datagrams over the four underlying internationally standardized CCSDS link layer protocols: – TM Space Data Link Protocol – TC Space Data Link Protocol – AOS Space Data Link Protocol – Proximity-1 Space Data Link Protocol 2) Recommend the standard CCSDS options for carrying IP datagrams within those CCSDS frames, including the mode where those IP datagrams under go header compression. 3) Utilize the “IP over CCSDS Links BOF” Concept Paper (http://public.ccsds.org/sites/cwe/sis-ipo/default.aspx) as the framework for the content of the CCSDS IP over CCSDS Recommended Practice specification.

Management Risk Mitigation Strategy
Schedule relies upon the assistance of British Space Agency, NASA, and ESA and on the allocation of adequate Agency resources to the WG. This work involves coordination between SLS area SLS-SLP WG and the SIS area SIS-DTN.
