ALTO extension: Entity Property Maps
draft-ietf-alto-unified-props-new-16
Abstract
This document extends the base Application-Layer Traffic Optimization
(ALTO) Protocol by generalizing the concept of "endpoint properties"
as applied to endpoints as defined by IP addresses to endpoints
defined by a wider set of objects. 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.
