A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Application-Layer Traffic Optimization WG of the IETF. Title : ALTO Cost Calendar Authors : Sabine Randriamasy Richard Yang Qin Wu Lingli Deng Nico Schwan Filename : draft-ietf-alto-cost-calendar-05.txt Pages : 25 Date : 2018-06-22 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.
