             Multi-domainn Information Exposure using ALTO
                 draft-lachos-alto-md-info-exposure-00

Abstract

   A common setting in emerging applications (e.g., data-intensive
   science applications, flexible inter-domain routing, multi-domain
   service function chaining) is that the traffic from a source to a
   destination traverses multiple networks domains.  Such multi-domain
   applications can benefit from network information exposure using
   ALTO.  This document summarizes the benefits of using such multi-
   domain information and discusses the ALTO design issues for gathering
   it.  Besides, it also presents key design requirements to be
   addressed in order to realize the proposal of providing multi-domain
   information by ALTO services.  Finally, another important objective
   of this document is to begin discussions into the ALTO WG concerning
   potential new items to be considered for the re-charter.
