Technical Summary

RFC 2544 has defined a benchmarking methodology for network
interconnect devices. RFC 5180 addressed IPv6 specificities and it
also provided a technology update but excluded IPv6 transition
technologies. RFC 8219 addressed IPv6 transition technologies,
including stateful NAT64. However, none of them discussed how to
apply RFC 4814 pseudorandom port numbers to any stateful NATxy
(NAT44, NAT64, NAT66) technologies. This document discusses why
using pseudorandom port numbers with stateful NATxy gateways is a
difficult problem. It recommends a solution limiting the port number
ranges and using two test phases (phase 1 and phase 2). It is shown
how the classic performance measurement procedures (e.g. throughput,
frame loss rate, latency, etc.) can be carried out. New performance
metrics and measurement procedures are also defined for measuring
maximum connection establishment rate, connection tear-down rate, and
connection tracking table capacity.

Working Group Summary

There was strong consensus, with broad agreement and no controversy.
As the shepherd says: "No threats to appeal and no indications of extreme discontent. Or discontent in general."

Document Quality

The document is clear and easy to read. It contains a snippet of code for test results, and
numerous test set up diagrams outlined in ASCII.
