Multi-Cost Application-Layer Traffic Optimization
RFC 8189, “Multi-Cost Application-Layer Traffic Optimization”, is a Proposed Standard document published in October 2017 by S. Randriamasy, W. Roome, N. Schwan. The canonical text is published by the RFC Editor.
Abstract
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.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
