Hi again,

Another update was to change the metric name "Availbandwidth" defined specifically for links in https://tools.ietf.org/wg/alto/draft-ietf-alto-performance-metrics/ to "bandwidthscore", more generic.
With the awareness though that ultimately these metrics names may have to be changed to nonsensical names such as "shoesize".

 Sabine

>>- section 5 "Use cases for ALTO Cost Schedule" has been dropped as other

>>Your feedback on the design is more than welcome before additional text

>>>>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 costs enabling an ALTO Server to provide "Cost
>>>>   Calendars".  These capabilities are applicable to time-sensitive ALTO
>>>>   metrics.  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.
