Flow control and sequencing techniques for telemetry packets

Anticipated changes in data telemetry are described, and the development of efficient techniques for packet sequencing and for controlling packet flow are discussed. The need for a real-time sequencing algorithm (SA) is explained. A flow control algorithm (FCA), which deals only with the aspect of flow control relevant to packet sequencing for a single experiment, could be embedded into a comprehensive flow control algorithm for a specific mission. The FCA controls packet flow so that the SA can sequence packets with the sequencing information provided. Techniques for sequencing and flow control are discussed, with attention to periodic, semiperiodic, and aperiodic flow control and sequencing.
