Hi all,

We just submitted a draft proposing an ALTO protocol extension allowing to decide 'where' and 'when' to connect. It is called "ALTO Cost Calendar".

In this draft the ALTO Calendar is presented as a Cost Mode that is applicable to time-sensitive ALTO metrics and allows applications using such metrics 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 and allow the ALTO Client to interpret the received ALTO values. This drafts proposes a set of Calendar attributes to be added to the IRD, for discussion in the ALTO WG. It also describes a number of use cases together with an example IRD and example ALTO transactions.

This draft leaves room for discussion any further comments and discussion are wellcome. 

Best regards
Sabine, Richard, Qin and Lingli

>>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.
