Abstract:
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. ALTO is realized by a client-server protocol. Before an
ALTO client can ask for guidance it needs to discover one or more
ALTO servers that can provide suitable guidance.
In some deployment scenarios, in particular if the information about
the network topology is partitioned and distributed over several ALTO
servers, it may be needed to discover an ALTO server outside of the
own network domain, in order to get appropriate guidance. This
document details applicable scenarios, itemizes requirements, and
specifies a procedure for ALTO cross-domain server discovery.
Technically, the algorithm specified in this document takes one
IP address and a U-NAPTR Service Parameter (i.e., "ALTO:http" or
"ALTO:https") as parameters. It performs DNS lookups (for NAPTR
resource records in the in-addr.arpa. or ip6.arpa. tree) and returns
one or more URI(s) of information resources related to that IP
address.
