Hi all,
I think SD-WAN can be covered by ALTO rechartered work item.
SD-WAN can connects the user to any application wherever it resides from the
data center to the cloud, and assesses the best path meeting the ideal
performance needs for a specific application. SD-WAN can also be used for cross
domain scenario.
For example, in some cloud-based WAN communications, stitching
multiple overlay tunnels in each domain are used for traffic policy enforcement
matters such as optimizing traffic distribution or to select the best SD-WAN
Edge for best user experience. A SD-WAN Edge can be partitioned into multiple
instance, for some instance which can redirect traffic to the payment GW to
offer better quality of service. ALTO protocol can be the best option for
SD-WAN Edge selection.

For the pointers above, the privacy requirement considered in this work is that
the network information of multiple domains should be exposed to applications
as a complete, unified aggregation, appearing as much as possible as from a
single (virtual) network. We design a network information obfuscation mechanism
so that the application is not able to associate any network resource
bottleneck information to any domain, reducing the risk of exposing network
vulnerability.
In addition, we also studied how to control the routing across multiple domains
to achieve more flexible end-to-end interdomain routing. Essentially, we
propose a mechanism that allows networks to expose their available interdomain
routes, just as BGP looking glasses, so that applications can control them. In
this setting, we consider the privacy setting where each network's BGP export
policies are private, and design interesting algorithms for applications to
select the best policy-compliant routes without knowing the export policies.
The following is the pointer for this study:

Above are our current efforts on extending ALTO to multi-domain settings. It
would be great if we can know more about the industry efforts on network
information exposure in multi-domain settings, and the privacy requirements of
operators. This would be extremely helpful to push this extension forward! :-)
