Abstract:
This memo defines metrics to evaluate whether a network has maintained packet
order on a packet-by-packet basis. It provides motivations for the new metrics and discusses the measurement
issues, including the context information required for all metrics. The memo first defines a reordered singleton,
and then uses it as the basis for sample metrics to quantify the extent of reordering
in several useful dimensions for network characterization or receiver design.
Additional metrics quantify the frequency of reordering and the distance between
separate occurrences. We then define a metric oriented toward assessment of reordering
effects on TCP. Several examples of evaluation using the various sample metrics
are included. An appendix gives extended definitions for evaluating order with
packet fragmentation. [STANDARDS-TRACK]
