Abstract:
   The goal of Application-Layer Traffic Optimization (ALTO) is to
   bridge the gap between network and applications by provisioning
   network related information in order to allow applications to make
   network informed decisions.  The present draft extends the ALTO cost
   information so as to broaden the decision possibilities of
   applications to not only decide 'where' to connect to, but also
   'when'.  This is useful to applications that need to schedule their
   data transfers and connections and have a degree of freedom to do so.
   ALTO guidance to schedule application traffic can also efficiently
   help for load balancing and resources efficiency.  Besides, the ALTO
   Cost Calendar allows to schedule the ALTO requests themselves and
   thus to save a number of ALTO transactions.

   This draft proposes new capabilities and attributes on filtered cost
   maps and endpoint cost maps enabling an ALTO Server to provide "Cost
   Calendars".  These capabilities are applicable to ALTO metrics with
   time-varying values.  With ALTO Cost Calendars, an ALTO Server
   exposes ALTO cost values in JSON arrays where each value corresponds
   to a given time interval.  The time intervals as well as other
   Calendar attributes are specified in the IRD and ALTO Server
   responses.
