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 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 the
utilization of the underlying network infrastructure.
This document enumerates requirements for specifying, assessing, or
