Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 22672 was prepared by the Consultative Committee for Space Data Systems (CCSDS) as
CCSDS 912.3-B-2, July 2010 and was adopted without modifications except those stated in Clause 2 of this
International Standard by Technical Committee ISO/TC 20, Aircraft and space vehicles, Subcommittee SC 13,
Space data and information transfer systems.
This second edition cancels and replaces the first edition (ISO 22672:2006), which has been technically
revised.

CCSDS RECOMMENDED STANDARD FOR SLE FSP SERVICE
STATEMENT OF INTENT
The Consultative Committee for Space Data Systems (CCSDS) is an organization officially
established by the management of its members. The Committee meets periodically to address
data systems problems that are common to all participants, and to formulate sound technical
solutions to these problems. Inasmuch as participation in the CCSDS is completely voluntary,
the results of Committee actions are termed Recommended Standards and are not
considered binding on any Agency.
This Recommended Standard is issued by, and represents the consensus of, the CCSDS
members. Endorsement of this Recommendation is entirely voluntary. Endorsement,
however, indicates the following understandings:
o Whenever a member establishes a CCSDS-related standard, this standard will be in
accord with the relevant Recommended Standard. Establishing such a standard
does not preclude other provisions which a member may develop.
o Whenever a member establishes a CCSDS-related standard, that member will
provide other CCSDS members with the following information:
-- The standard itself.
-- The anticipated date of initial operational capability.
-- The anticipated duration of operational service.
o Specific service arrangements shall be made via memoranda of agreement. Neither
this Recommended Standard nor any ensuing standard is a substitute for a
memorandum of agreement.
No later than five years from its date of issuance, this Recommended Standard 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 Recommended Standard is issued, existing
CCSDS-related member standards and implementations are not negated or deemed to be non-
CCSDS compatible. It is the responsibility of each member to determine when such
standards or implementations are to be modified. Each member is, however, strongly
encouraged to direct planning for its new standards and implementations towards the later
version of the Recommended Standard.

CCSDS RECOMMENDED STANDARD FOR SLE FSP SERVICE
1 INTRODUCTION
1.1 PURPOSE OF THIS RECOMMENDED STANDARD
This Recommended Standard defines the Forward Space Packet (FSP) service in
conformance with the transfer services specified in reference [1], Cross Support Reference
Model―Part 1: SLE Services. The FSP service is a Space Link Extension (SLE) transfer
service that enables a mission to send Space Packets to a spacecraft in sequence-controlled or
expedited mode.
1.2 SCOPE
This Recommended Standard defines, in an abstract manner, the FSP service in terms of:
a) the operations necessary to provide the transfer service;
b) the parameter data associated with each operation;
c) the behaviors that result from the invocation of each operation; and
d) the relationship between, and the valid sequence of, the operations and resulting
behaviors.
It does not specify:
a) individual implementations or products;
b) the implementation of entities or interfaces within real systems;
c) the methods or technologies required to radiate Space Packets to a spacecraft and to
acquire telemetry frames from the signals received from that spacecraft for extraction
of the Operational Control Field;
d) the methods or technologies required for communications; or
e) the management activities necessary to schedule, configure, and control the FSP
service.
NOTE – While the FSP service as described in reference [1] is conceived to handle a
variety of packet data structures, this version of the FSP Recommended Standard
is restricted to the handling of Space Packets as defined in reference [6].
This version of the FSP Recommended Standard is specific to the transfer of Space Packets
to be transmitted via the Telecommand protocol stack as defined in references [3], [4], and
[5]. The Cross Support Reference Model (reference [1]) specifies that the FSP service may
also be used in conjunction with the Advanced Orbiting System protocol stack, but that mode
of operation is outside the scope of this version of the Recommended Standard.

ISO 22672:2011(E)
CCSDS RECOMMENDED STANDARD FOR SLE FSP SERVICE
The FSP service is provided in the online delivery mode, as defined in reference [1]. The
offline delivery mode is the subject of further study.
1.3 APPLICABILITY
1.3.1 APPLICABILITY OF THIS RECOMMENDED STANDARD
This Recommended Standard provides a basis for the development of real systems that
implement the FSP service. Implementation of the FSP service in a real system additionally
requires the availability of a communications service to convey invocations and returns of
FSP service operations between FSP service users and providers. This Recommended
Standard requires that such a communications service ensures that invocations and returns of
operations are transferred:
a) in sequence;
b) completely and with integrity;
c) without duplication;
d) with flow control that notifies backpressure to the application layer in the event of
congestion; and
e) with notification to the application layer in the event that communications between
the FSP service user and the FSP service provider are disrupted, possibly resulting in
a loss of data.
It is the specific intent of this Recommended Standard to define the FSP service in a manner
that is independent of any particular communications services, protocols, or technologies.
1.3.2 LIMITS OF APPLICABILITY
This Recommended Standard specifies the FSP service that may be provided by an SLE
System for inter-Agency cross support. It is neither a specification of, nor a design for, real
systems that may be implemented for the control and monitoring of existing or future
missions.
1.4 RATIONALE
The goal of this Recommended Standard is to create a standard for interoperability between
the tracking stations and/or ground data handling systems of various agencies and the users of
forward services.
