Hi all, I've been doing some review and clean up of my local IE database and I see around a dozen IEs related to latency and RTT from various exporters/vendors. This seems like a measurement that could use a standard IE for reporting. Here are my thoughts so far... Name: latencyMilliseconds Type: unsigned32 Semantic: quantity Description: latency measured in milliseconds. Units: milliseconds Name: roundTripTimeMilliseconds Type: unsigned32 Semantic: quantity Description: Round trip time measured in milliseconds. Units: milliseconds Perhaps the above needs to be fleshed out with some Extended Field Specifiers as has been discussed recently for jitter. On a related note an IE that I am not seeing from most of the exporters sending latency information, but which can be useful when diagnosing problems is out of order packet information. Name: outOfOrderPacketDeltaCount Type: unsigned64 Semantic: deltaCounter Description: The number of out of order packets since the previous report (if any) for this Flow at the Observation Point. Units: packets Name: outOfOrderPacketTotalCount Type: unsigned64 Semantic: totalCounter Description: The total number of out of order packets for this Flow at the Observation Point since the Metering Process (re-)initialization for this Observation Point. Units: packets -Andrew _______________________________________________ IPFIX mailing list [email protected] https://www.ietf.org/mailman/listinfo/ipfix
