Dear all,
here is my write-up for the publication request on
draft-ietf-alto-performance-metrics:
1. Summary
Jan Seedorf is the document shepherd for
draft-ietf-alto-performance-metrics. Martin Duke is the responsible Area
Director.
The ALTO base protocol (RFC7285) defines only a single cost metric, the
generic “routing cost” metric. As new ALTO use cases are being
envisioned (e.g. CDN, 5G, data-intensive science applications, flexible
inter-domain routing, etc.), the demand for more concrete cost metrics
to be conveyed via the ALTO protocol arises. This document defines a
multitude of such concrete ALTO cost metrics, such as one-way delay, hop
count, residue bandwidth, and several more.
This document is targeted as a Standards Track document (Proposed
Standard). This designation is appropriate as the document contains
normative behaviour and specifies several additions to the IANA "ALTO
Cost Metric Registry" that should be adhered to by the communicating
entities in order to realize the extension.
2. Review and Consensus
The document was introduced originally in 2013 and has been iterated and
presented at IEFT meetings many times. It was adopted as WG item in
2016, showing the general consensus in the ALTO WG for adding more
concrete costs metrics to the ALTO protocol.
The proposed metrics have been discussed extensively at IETF meetings
and on the mailing list. Since some of these metrics must to be
specified in an unambiguous fashion with clear semantics, external help
from IETF experts was obtained: in 2018 a “Tsvart early review” was
performed by Brian Trammell. The outcome has been discussed on the
mailing list and has been addressed in newer versions of the document.
Also, advice from IETF experts from the IPPM WG on the semantics of the
proposed metrics was obtained, discussed, and incorporated into the
document. All of these changes and semantics have been presented to the
ALTO WG multiple times.
In summary, there is clear consensus for
draft-ietf-alto-performance-metrics in the ALTO WG, and it provides very
useful cost metric extensions needed for many of the currently
envisioned (future) ALTO use cases. A WGLC has successfully been passed
with no objections, and extensive reviews were provided by various
members of the WG and have all been addressed.
3. Intellectual Property
The shepherd confirms that each author has stated to him that to the
best of his/her (i.e. the author’s) knowledge, all IPR related to this
document has been disclosed.
4. Other Points
Note any downward references (see RFC 3967) and whether they appear in
the DOWNREF Registry
(http://trac.tools.ietf.org/group/iesg/trac/wiki/DownrefRegistry), as
these need to be announced during Last Call.
All normative references are ok (with respect to RFC 3967) as they are
all towards documents with standards-level “Proposed Standards”,
“Internet Standard”, or “BCP”.
