Technical Summary
This document extends the base Application-Layer Traffic Optimization
(ALTO) Protocol by generalizing the concept of "endpoint properties"
to entities defined by a wide set of objects, instead of only IP
addresses. Further, these properties are presented as maps, similar
to the network and cost maps in the base ALTO protocol. The protocol
is extended in two major directions. First, from endpoints
restricted to IP addresses to entities covering a wider and
extensible set of objects; second, from properties on specific
endpoints to entire entity property maps. These extensions introduce
additional features allowing entities and property values to be
specific to a given information resource. This is made possible by a
generic and flexible design of entity and property types.
Working Group Summary
The working group process has been uncontroversial.
Document Quality
There are three known implementations. As with all ALTO documents,
the work does not have a clear deployment roadmap.
Personnel
The document shepherd is Vijay K. Gurbani, and the responsible area director is
Martin Duke.
