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
informed decisions. The present draft proposes to extend the cost
information provided by the ALTO protocol. The purpose is to broaden
the decision possibilities of applications to not only decide 'where'
to connect to, but also 'when'. This is useful to applications that
have a degree of freedom on when to schedule data transfers, such as
non- instantaneous data replication between data centers or service
provisioning to end systems with irregular connectivity. ALTO
guidance to schedule application traffic can also efficiently help
for load balancing and resources efficiency.
The draft specifies a new Cost Mode, "Calendar" Mode, that is
applicable to time-sensitive ALTO metrics and allows Applications to
carefully schedule their connections or data transfers. In the
Calendar Mode, 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. Besides the functional time-shift enhancement the ALTO Cost
Calendar also allows to schedule the ALTO requests themselves and
thus save a number of ALTO transactions.
