BS ISO 20206:2015 pdf free.Space data and information transfer systems- IP over CCSDS space links.
BS ISO 20206 This document describes the recommended method for transferring IP PDUs over CCSDS SDLPS: Telecommand (TC), Telemetry (TM), Advanced Orbiting Systems (AOS), and Proximity-1 (Prox-1). IP PDUs are transferred by encapsulating them, one-for -one, within CCSDS Encapsulation Packets. The Encapsulation Packets are transferred directly within one or more CCSDS SDLP Transfer Frames. This method uses the CCSDS Internet Protocol Extension (IPE) convention in conjunction with the CCSDS Encapsulation Service over CCSDS AOS, TM, or TC Virtual Channel Packet (VCP) Service, TC Multiplexer Access Point Packet (MAPP) Service, or Prox-1.The CCSDS IPE convention is to prepend the CCSDS IPE octet(s) to each IP PDU,encapsulate the result in a CCSDS Encapsulation Packet (see reference [3]), and transport the Encapsulation Packet within one or more CCSDS SDLP frames (see references [4]-[7] and figure 2-1). This method is recommended for all IP PDUs identified in reference [8]. It is the task of the IPoC service provider to generate the IPE header and prepend it to the IP PDU on the sending end. On the receiving end, the IPoC service provider extracts the IPE header and uses the IPE value to route the IP PDU to the applicable IP protocol handler for transfer across the receiving end.There often are many IP data types that require encapsulation. The exact number of protocols depends on the mission and its requirements. These protocols are fully defined in other data standards. Thus the intent here is to identify only auxiliary PDU formats that are often used in support of IP. As a comparison, serial links between routers often carry the 16-bit Point-to-Point Protocol (PPP) protocol field, and the Ethernet PDUs carry a 16-bit Ethernet type field. In these cases, the enumerations of the protocols are defined by the Internet Assigned Numbers Authority (IANA) and the Institute of Electrical and Electronics Engineers (IEEE),respectively. The tables containing the enumerations then point to the standards that define the protocols themselves.The alternative approach would have been to encapsulate a conventional link layer, such as Multiprotocol over Frame Relay, and use its methods for identifying the auxiliary PDU formats.BS ISO 20206 pdf download.
