Abstract:
   The Application-Layer Traffic Optimization (ALTO) [RFC7285] protocol
   provides network related information to client applications so that
   clients may make informed decisions.  To that end, an ALTO Server
   provides Network and Cost Maps.  Using those maps, an ALTO Client can
   determine the costs between endpoints.

   However, the ALTO protocol does not define a mechanism to allow a
   client to obtain updates to those maps, other than by periodically
   re-fetching them.  Because the maps may be large (potentially tens of
   megabytes), and because only parts of the maps may change frequently
   (especially Cost Maps), that can be extremely inefficient.

   Therefore this document presents a mechanism to allow an ALTO Server
   to provide updates to ALTO Clients.  Updates can be both immediate,
   in that the server can send updates as soon as they are available,
   and incremental, in that if only a small section of a map changes,
   the server can send just the changes.
