Title : ALTO Protocol

Applications using the Internet already have access to some 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 network
application clients. What is missing is knowledge of the underlying
network topologies from the point of view of ISPs. In other words,
what an ISP 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 ISPs, other
entities such as content service providers could also operate an ALTO
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.
