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-1, November 2004) 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.

CCSDS RECOMMENDATION FOR SLE FORWARD SPACE PACKET SERVICE
STATEMENT OF INTENT
The Consultative Committee for Space Data Systems (CCSDS) is an organization officially
established by the management of member space Agencies. 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
Recommendations and are not considered binding on any Agency.
This Recommendation is issued by, and represents the consensus of, the CCSDS Plenary
body. Agency endorsement of this Recommendation is entirely voluntary. Endorsement,
however, indicates the following understandings:
o Whenever an Agency establishes a CCSDS-related standard, this standard will be in
accord with the relevant Recommendation. Establishing such a standard does not
preclude other provisions that an Agency may develop.
o Whenever an Agency establishes a CCSDS-related standard, the Agency will provide
other CCSDS member Agencies 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
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.

CCSDS RECOMMENDATION FOR SLE FORWARD SPACE PACKET SERVICE
FOREWORD
This document is a technical Recommendation for use in developing ground systems for
space missions and has been prepared by the Consultative Committee for Space Data
Systems (CCSDS). The Space Link Extension (SLE) Forward Space Packet (FSP) Service
described herein is intended for missions that are cross-supported between Agencies of the
CCSDS.
This Recommendation specifies a data service that extends certain of the space-to-ground
communications services previously defined by CCSDS (references [3], [4], [5], and [6])
within the framework established by the CCSDS SLE Reference Model (reference [1]). It
allows implementing organizations within each Agency to proceed with the development of
compatible, derived Standards for the ground systems that are within their cognizance.
Derived Agency Standards may implement only a subset of the optional features allowed by
the Recommendation and may incorporate features not addressed by the Recommendation.
Through the process of normal evolution, it is expected that expansion, deletion or
modification to this document may occur. This Recommendation is therefore subject to
CCSDS document management and change control procedures, as defined in reference [G1].
Current versions of CCSDS documents are maintained at the CCSDS Web site:
http://www.ccsds.org/
Questions relating to the contents or status of this document should be addressed to the
CCSDS Secretariat at the address indicated on page ii.

CCSDS RECOMMENDATION FOR SLE FORWARD SPACE PACKET SERVICE
1 INTRODUCTION
1.1 PURPOSE OF THIS RECOMMENDATION
This Recommendation 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 Recommendation 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 Recommendation is
restricted to the handling of Space Packets as defined in reference [6].
1.3 APPLICABILITY
1.3.1 APPLICABILITY OF THIS RECOMMENDATION
This Recommendation 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
CCSDS 912.3-B-1 Page 1-1 November 2004

---------------------- Page: 16 ----------------------
ISO 22672:2006(E)
CCSDS RECOMMENDATION FOR SLE FORWARD SPACE PACKET SERVICE
operations between FSP service users and providers. This Recommendation 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 Recommendation 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 Recommendation 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 Recommendation 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.
1.5 DOCUMENT STRUCTURE
1.5.1 ORGANIZATION
This Recommendation is organized as follows:
a) section 1 provides the purpose, scope, applicability, and rationale of this
Recommendation and lists definitions, nomenclature, conventions, and references
used throughout the Recommendation;
b) section 2 provides an overview of the FSP service including a functional description,
the service management context, and protocol considerations;
c) section 3 specifies the operations of the FSP service;
