Hello ALTO WG,

At the last IETF, there was a PANRG session during which, as they have shown interest in the ALTO work, I gave a lightning talk on ALTO and its relevant extensions, see slides at https://datatracker.ietf.org/meeting/100/materials/slides-100-panrg-04-the-ietf-alto-protocol-and-its-extensions/

The goal of PANRG is to extend path awareness from the control plane to the edge with mechanisms allowing: Endpoint discovery of paths, explicit association of properties to paths by endpoints, explicit endpoint selection of paths. The identified underlying hard problems are mainly: conflict of interest between hosts and networks, path property exposition by the network to third parties considering network confidentiality and information aggregation level, diversity of timescale for configuration, discovery, selection and dissemination. The PANRG would like to leverage its work on existing IETF protocols and their potential extensions.

The last presentation was upon a draft by Brian Trammel, one of the RG chairs, to open the discussions.
See the slides at https://datatracker.ietf.org/meeting/100/materials/slides-100-panrg-06-open-questions/
Regarding question "how do endpoints discover trustworthy path properties?", the slides mention that SCION (a path-aware Internet architecture presented at IETF99) and ALTO represent points in this design space.

The other presentations are on https://datatracker.ietf.org/meeting/100/session/panrg

I think it is worth getting in touch with this RG to see how ALTO can serve their goals. As they focus on the mechanisms leveraging on protocols rather than on protocols themselves, they may expose use cases motivating existing and future protocol extensions and defining needs for particular features.

Cheers,
Sabine
