Hi Martin, I agree with Luis. RFC 7971 list PCE as a potential data source for ALTO server - https://datatracker.ietf.org/doc/html/rfc7971#autoid-19 Further RFC 7491 attempts to capture some of the possible PCE and ALTO interactions where PCE and ALTO complement each other. Thanks! Dhruv On Tue,

Hi Qin, This is meant to be more about to health of the ALTO server itself instead of that of the underlying network. This is to monitor the functioning of the ALTO protocol with various statistics and counters. Is the use of the term "ALTO-specific performance metrics", a source of confusion? We

Hi, Does the erratum ask that we remove priv: from the IANA registry as well? https://www.iana.org/assignments/alto-protocol/alto-protocol.xhtml#cost-metrics https://www.iana.org/assignments/alto-protocol/alto-protocol.xhtml#endpoint-property-types I think that would be unfortunate. Perhaps some

Hi Qin, IMHO we should limit the hop count to the output we expect if we run traceroute to the endpoint thus not indicate any lower layer devices in this. Hop count by its nature is a rough metric and one must rely on other metrics like routing cost, delay to judge an optimum endpoint. Dhruv On

Hi Qin, One point to note that would be that metrics in IGP drafts are in terms of a TE link, in ALTO we need to worry about E2E cost ( or cost of an abstract link incase when ALTO also convey an abstract topology), so these cost metrics are composite metrics. ALTO server may rely on database pop
