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.
