🌸 Detailed Description 🌸

RTE Traffic Metering πŸ’…

here's the tea β€” these are the traffic metering algorithms, count 'em:

  1. Single Rate Three Color Marker (srTCM): defined by IETF RFC 2697
  2. Two Rate Three Color Marker (trTCM): defined by IETF RFC 2698
  3. Two Rate Three Color Marker (trTCM): defined by IETF RFC 4115

Definition in file rte_meter.h.
