Abstract:
This document is an extension to the base Application-Layer Traffic
Optimization (ALTO) protocol. It extends the ALTO Cost Map service
and ALTO Property Map service so that the application can decide
which endpoint(s) to connect based on not only numerical/ordinal cost
values but also details of the paths. This is useful for
applications whose performance is impacted by specified 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
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.
