Full title and description
Space data and information transfer systems — IP over CCSDS space links. This International Standard specifies the recommended method for transferring Internet Protocol (IP) Protocol Data Units (PDUs) over CCSDS (Consultative Committee for Space Data Systems) space link protocols, enabling IP-based networking across space-to-space and space-to-ground links.
Abstract
ISO 20206:2015 addresses the recommended method for transferring IP Protocol Data Units (PDUs) over CCSDS space links, describing the IP over CCSDS (IPoC) service, encapsulation and mapping to space data link layer protocols to support interoperable IP communication in space environments.

Scope
ISO 20206:2015 defines the recommended method and service for carrying IP PDUs over CCSDS space data link protocols. The scope covers encapsulation and mapping techniques, service definitions (IPoC), considerations for IPv4/IPv6 PDUs, interaction with CCSDS link-layer protocols (for example those specified in CCSDS Blue Books), and interoperability guidance for spacecraft and ground segment implementations. The standard aligns the CCSDS recommended approach with ISO standardization.
Key topics and requirements
- Definition of the IPoC (IP over CCSDS) service and expected behavior for IP PDU transfer over space links.
- Encapsulation and framing rules for carrying IPv4 and IPv6 PDUs within CCSDS space data link protocols.
- Mapping to CCSDS space data link layer primitives and handling of link-layer-specific constraints (MTU, timing, retransmission behaviors).
- Fragmentation and reassembly considerations across space links where MTU or segmentation differs from terrestrial networks.
- Interoperability guidance to ensure consistent implementation across spacecraft, ground stations and network nodes using CCSDS protocols.
- Normative references to CCSDS publications that define the underlying space link protocols and encapsulation mechanics.
Key technical concepts derive from both the ISO publication and the CCSDS recommended standard that ISO formalized.
Typical use and users
Primary users are spacecraft communications engineers, mission network architects, ground-station and satellite-communications vendors, space agencies and mission integrators who need to implement or operate IP networking over CCSDS-compliant space links. The standard is used when missions require IP-based services (routing, telemetry/telcommand integration, onboard networking) to operate reliably over space link protocols.
Related standards
Closely related publications include the CCSDS recommended standard "IP over CCSDS Space Links" (CCSDS 702.1 series) on which the ISO text is based, other ISO 202xx-series space data and information transfer systems standards, and higher-level networking and encapsulation references such as ISO/IEC and CCSDS documents on encapsulation services and space link protocols. Implementers commonly consult the CCSDS Blue Books for protocol details alongside this ISO standard.

FAQ
Q: What is this standard?
A: ISO 20206:2015 is an International Standard that specifies a recommended method for transferring IP Protocol Data Units (PDUs) over CCSDS space links (IPoC), enabling IP-based communication over space-to-space and space-to-ground links.
Q: What does it cover?
A: It covers the definition of the IPoC service, encapsulation and mapping of IPv4/IPv6 PDUs to CCSDS space data link layer protocols, fragmentation/reassembly considerations, and interoperability guidance for spacecraft and ground segment implementations.
Q: Who typically uses it?
A: Space agencies, satellite and spacecraft communications engineers, mission architects, ground-segment operators, and commercial vendors building space link and onboard networking equipment.
Q: Is it current or superseded?
A: ISO 20206:2015 was published on 11 August 2015 (Edition 1) and is recorded as a published/confirmed ISO standard; the ISO lifecycle shows periodic review (standards are reviewed approximately every five years). Confirmation activity is recorded in national/standards databases (confirmation noted in 2023). Users should verify any national adoptions or later revisions prior to procurement or implementation.
Q: Is it part of a series?
A: Yes — it is part of the ISO 202xx family of standards addressing space data and information transfer systems (other nearby numbers address related space link protocols, identifiers, security and data formats). It also corresponds to CCSDS publications (for example CCSDS 702.1) that provide the Blue Book technical detail.
Q: What are the key keywords?
A: IP over CCSDS, IPoC, CCSDS, space data link, encapsulation, IPv4, IPv6, fragmentation, spacecraft networking, interoperability.
