Many Internet applications are used to access resources such as
pieces of information or server processes that 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 that have to select one or several hosts
from a set of candidates capable of providing a desired resource.
This memo discusses deployment-related issues of ALTO. It addresses
different use cases of ALTO such as peer-to-peer file sharing and
Content Delivery Networks (CDNs) and presents corresponding examples.
The document also includes recommendations for network administrators
and application designers planning to deploy ALTO, such as
recommendations on how to generate ALTO map information.
This document is a product of the Application-Layer Traffic Optimization Working Group of the IETF.
