Hi, All:

As we know, the CDN makes use of an ALTO server to choose a better CDN
surrogate. However CDN may not be able to passively listen to routing
protocol, nor may have access to other network topology data (e.g.,
inventory databases).
Based on our analysis, CDN is built on top of underlying network which runs
these routing protocols and the network topology can be gathered via BGP-LS
or NETCONF YANG. I2RS working group have published various network topology
models such as L3 topology model, L2 topology model. We are wondering
whether we can use NETCONF protocol to collect these network topology data
and translate into ALTO map data.
Here is the relevant draft we proposed in ALTO working group:
https://datatracker.ietf.org/doc/html/draft-hzx-alto-network-topo-00.txt
Please let us know if you have any comments or suggestions.

Thanks and Regards,
Cheng Zhou

Abstract:
   RFC8345 introduces an abstract YANG data model to represent network
   topologies.  This document uses ALTO protocol to provide access to
   network Topology data such as L3 topology data , data center network
   topology data, flexible enough to enable querying of specific and
   possibly aggregated data.
