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.

Title : Network Topology data retrieval using ALTO protocol Authors : Hanshu Hong Cheng Zhou Chongfeng Xie Qiufang Ma Filename : draft-hzx-alto-network-topo-00.txt Pages : 12 Date : 2021-06-24 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.
