Hi,
Kai, thanks for the good notes.
Sorry I’ve not been able to attend lately. I probably won’t be able to attend
on the new time until Europe moves to winter time in few weeks time.

Subject: [alto] Meeting minutes for Oct 13, 2020
Dear all,
In this week's meeting, we first went over the progress of 5 WG documents as
follows:
- cost calendar: all co-authors have approved the publication
- unified property: 2 reviews received for WGLC and is under revision
- performance metrics: 3 reviews received for WGLC
- path vector: 1 review received and Luis proposes to give another review by
Oct 26
- CDNI: held by WG
Chunshan gave a presentation on the proposed changes to the rechartering items
[1], including cellular information, IB/OB signaling and transport protocol
extensions. In particular, he shared information from 3GPP on IB/OB signaling,
indicating that IB/OB signaling should be combined for cellular information
exposure. It is suggested that Chunshan submits the proposed changes to the
rechartering document and brings the issues to the ALTO mailing list to
initiate discussions.
Sabine and Gang discussed the issues of exposing cellular information. Key
questions include what information should be exposed, and how to handle the
freshness of cellular information. The Tecent and CMCC team has already
categorized some cellular information to 3 different levels and several
categories. It is suggested to start with radio channel information.
Sabine proposed to gain a better understanding of the issue by answering the
following questions:
- What metric is important to the quality of applications?
- To what extent is it possible to expose?
- Which time granularity is the ALTO client/server able to support?
- What decisions can a client make?
Gang mentioned that the time granularity depends on the transmission delay and
the transmission protocol (whether it's IB or OB, signaling overhead). He also
proposed to bring the issues to the mailing list to engage a broader audience.
The link to the meeting minutes is attached below [2].
Sabine, Gang, Chunshan: Please correct me if I missed or misinterpreted some
points.
Best,
Kai
