In IETF90 Toronto meeting, one question was raised on draft-wu-alto-te-metrics
https://tools.ietf.org/html/draft-wu-alto-te-metrics-06
is whether we redefine metric defined somewhere else.
Here is the clarification:
I think this is not metric redefinition and what we do is to feed TE metric gathered using routing protocol into ALTO server and provide such TE metric to ALTO client.
ALTO server may aggregate metric data gathered using various routing protocols. But the purpose is to normalize the data and provide it to ALTO client in more useful way,
e.g., calculate end to end metric based on hop by hop metric and expose it to the ALTO client.
