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 procedure specified in this document takes one
   IP address or prefix 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 or prefix.
