AN EXTENSION TO THE CCSDS PACKET TELEMETRY TO SUPPORT DATA TRANSFER WITH VARIOUS SERVICE REQUIREMENTS

International Telemetering Conference Proceedings / October 27-30, 1997 / Riviera Hotel and Convention Center, Las Vegas, Nevada / A spacecraft complying with the CCSDS Packet Telemetry standard generates telemetry
data as a stream of packets. Generally, each packet has different requirements for data
transfer characteristics (such as delay and reliability). These requirements are called
Quality of Service (QoS) requirements. This paper proposes an extension to the CCSDS
Packet Telemetry standard to specify QoS requirements of each packet. The method
proposed in this paper is to associate with each packet (1) a level of delay tolerance and
(2) a level of loss tolerance. This paper shows how packets should be handled based on
this QoS information, and demonstrates that most of the QoS requirements for telemetry
data transfer can be met by using this information. This paper also addresses some topics
for future investigations.
