Ballot Text

Technical Summary

ALTO reports routing cost as a metric for clients to evaluate potential routes and/or destinations.  This draft expands the vocabulary to include network delay, jitter, packet loss rate, hop count, and bandwidth, metrics likely to be of more interest to clients.

Working Group Summary

Most aspects of this document were uncontroversial.

A few reviewers noted that as many of the text strings are not standardized, much information delivered by this extension will not be machine-readable. While this limits the use cases somewhat, this addition was judged to be out of scope.

Document Quality

   There is no strong evidence that this will be widely deployed or implemented, though it self-evidently provides metrics that should encourage use by clients.

   Brian Trammell conducted an early review that aligned the metrics
   with definitions in the IPPM working group.

Personnel

   The Shepherd is Jan Seedorf. The responsible AD is Martin Duke.
