Abstract:
Networking applications today already have access to a great amount
of Inter-Provider network topology information. For example, views
of the Internet routing table are easily available at looking glass
servers and entirely practical to be downloaded by clients. What is
missing is knowledge of the underlying network topology from the ISP
or Content Provider (henceforth referred as Provider) point of view.
In other words, what a Provider prefers in terms of traffic
optimization -- and a way to distribute it.
The ALTO Service provides network information (e.g., basic network
location structure, 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 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 providers and third parties could
also operate this service. Applications that could use this service
are those that have a choice in connection endpoints. Examples of
such applications are peer-to-peer (P2P) and content delivery
networks.
