Abstract:
   Applications using the Internet already have access to topology
   information of Internet Service Provider (ISP) networks.  For
   example, views to Internet routing tables at looking glass servers
   are available and can be practically downloaded to many application
   clients.  What is missing is knowledge of the underlying network
   topologies from the point of view of ISPs (henceforth referred as
   Providers).  In other words, what a Provider prefers in terms of
   traffic optimization -- and a way to distribute it.

   The Application-Layer Traffic Optimization (ALTO) Service provides
   network information (e.g., basic network location structure and
   preferences of network paths) with the goal of modifying network
   resource consumption patterns while maintaining or improving
   application performance.  The basic information of ALTO is based on
   abstract maps of a network.  These maps provide a simplified view,
   yet enough information about a network for applications to
   effectively utilize them.  Additional services are built on top of
   the maps.

   This document describes a protocol implementing the ALTO Service.
   Although the ALTO Service would primarily be provided by the network
   operator (e.g., an ISP), content service providers and third parties
   could also operate this service.  Applications that could use this
   service are those that have a choice to which end points to connect.
   Examples of such applications are peer-to-peer (P2P) and content
   delivery networks.
