The IESG contact persons are Zaheduzzaman Sarker and Martin Duke. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-alto-unified-props-new/
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.
