The Application-Layer Traffic Optimization (ALTO) protocol, specified
in RFC 7285, defines several services that return various metrics
describing the costs between network endpoints.
This document defines a new service that allows an ALTO Client to
retrieve several cost metrics in a single request for an ALTO
filtered cost map and endpoint cost map. In addition, it extends the
constraints to further filter those maps by allowing an ALTO Client
to specify a logical combination of tests on several cost metrics.
This document is a product of the Application-Layer Traffic Optimization Working Group of the IETF.
This is now a Proposed Standard.
STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements. Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the
standardization state and status of this protocol. Distribution of this
