This document is an extension to the base Application-Layer Traffic
Optimization (ALTO) protocol. It extends the ALTO cost map and ALTO
property map services so that an application can decide to which
endpoint(s) to connect based not only on numerical/ordinal cost
values but also on fine-grained abstract information regarding the
paths. This is useful for applications whose performance is impacted
by specific components of a network on the end-to-end paths, e.g.,
they may infer that several paths share common links and prevent
traffic bottlenecks by avoiding such paths. This extension introduces
a new abstraction called the "Abstract Network Element" (ANE) to
represent these components and encodes a network path as a vector of
ANEs. Thus, it provides a more complete but still abstract graph
representation of the underlying network(s) for informed traffic
optimization among endpoints.

This document is a product of the Application-Layer Traffic Optimization Working Group of the IETF.
