ISO 21080:2016

OVERVIEW

1.1 Purpose

ISO 21080:2016 defines a Recommended Standard for the CCSDS Licklider Transmission Protocol (LTP) and associated service for application in the space environment. LTP provides optional reliability mechanisms on top of an underlying (usually data link) communication service.

LTP is intended for use over the current and envisaged packet delivery services used in the space environment, including:

- CCSDS conventional packet telecommand;

- CCSDS conventional packet telemetry.

For space data links, LTP will typically be deployed over a CCSDS data link that supports CCSDS Encapsulation Packets so that one LTP segment can be encapsulated in a single Encapsulation Packet. LTP may also operate over a wide variety of ground-network services including those specified by the CCSDS for cross-support purposes.
