IPv6 Performance and Diagnostic Metrics Destination Option
draft-elkins-6man-ipv6-pdm-dest-option-01
Abstract
To diagnose problems for a number of Enterprise Data Center Operators
(EDCO), two metrics are critical for timely end-to-end problem
resolution, both real-time and after the fact, without impacting an
operational production network. They are: packet sequence number and
packet timestamp. Packet sequence number is required for diagnostics.
Packet timestamp is required to calculate end-to-end response time.
Current methods are inadequate for these purposes because they assume
unreasonable access to intermediate devices, are cost prohibitive,
require infeasible changes to a running production network, and / or
do not provide timely data. This document solves these problems with
a new destination option, the Performance and Diagnostic Metrics
destination option (PDM).
