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.
