If the ALTO server can accurately reflect the topology of the underlying network, there is no need for the CDN to listen to routing protocols. All the CDN needs to do is to interface with the ALTO Server, which makes the CDN implementation a lot simpler. This in turn allows for better interoperability between CDNs and interoperability between the network and different CDNs operating on top of it. Protocol selection aside, this discussion should be about the APIs and utility of standardizing the map exchange. WRT the discussion of the Network API: the pro is that ALTO servers will have the same information, the con is that they won't and have a technology with different maps and views of the network. /Jan _______________________________________________ alto mailing list [email protected] https://www.ietf.org/mailman/listinfo/alto
