Abstract:
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 which
endpoint(s) to connect based on not only numerical/ordinal cost
values but also fine-grained abstract information 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.
