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 Extension: Path Vector Cost Type Authors : Greg Bernstein Shiwei Dawn Chen Kai Gao Young Lee Wendy Roome Michael Scharf Y. Richard Yang Jingxuan Jensen Zhang Filename : draft-ietf-alto-path-vector-02.txt Pages : 26 Date : 2017-12-18 Abstract: The Application-Layer Traffic Optimization (ALTO) protocol [RFC7285] has defined several resources and services to provide clients with basic network information. However, the base ALTO protocol and latest extensions only provide end-to-end metrics, which are insufficient to satisfy the demands of solving more complex network optimization problems. This document introduces an extension to the base ALTO protocol, namely the path-vector extension, which allows ALTO clients to query information such as capacity regions for a given set of flows. A non-normative example called multi-flow scheduling is presented to illustrate the limitations of existing ALTO (endpoint) cost maps. After that, details of the extension are defined.
