   Many Internet applications are used to access resources, such as
   pieces of information or server processes, which are available in
   several equivalent replicas on different hosts.  This includes, but
   is not limited to, peer-to-peer file sharing applications.  The goal
   of Application-Layer Traffic Optimization (ALTO) is to provide
   guidance to applications, which have to select one or several hosts
   from a set of candidates capable of providing a desired resource.
   This guidance shall be based on parameters that affect performance
   and efficiency of the data transmission between the hosts, e.g., the
   topological distance.  The ultimate goal is to improve performance
   (or Quality of Experience) in the application while reducing resource
   consumption in the underlying network infrastructure.

   This document enumerates requirements for specifying, assessing, or
   comparing protocols and implementations.
