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 : An ALTO Extension: Path Vector Authors : Kai Gao Young Lee Sabine Randriamasy Yang Richard Yang Jingxuan Jensen Zhang Filename : draft-ietf-alto-path-vector-25.txt Pages : 69 Date : 2022-03-20 Abstract: This document is an extension to the base Application-Layer Traffic Optimization (ALTO) protocol. It extends the ALTO Cost Map and ALTO Property Map services so that an application can decide which endpoint(s) to connect based on not only numerical/ordinal cost values but also fine-grained abstract information of the paths. This is useful for applications whose performance is impacted by specified components of a network on the end-to-end paths, e.g., they may infer that several paths share common links and prevent traffic bottlenecks by avoiding such paths. This extension introduces a new abstraction called Abstract Network Element (ANE) to represent these components and encodes a network path as a vector of ANEs. Thus, it provides a more complete but still abstract graph representation of the underlying network(s) for informed traffic optimization among endpoints.
