The IESG has received a request from the Application-Layer Traffic Optimization WG (alto) to consider the following document: - 'ALTO Extension: Path Vector' <draft-ietf-alto-path-vector-15.txt> as Proposed Standard
The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the [email protected] mailing lists by 2021-08-25. Exceptionally, comments may be sent to [email protected] instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract This document is an extension to the base Application-Layer Traffic Optimization (ALTO) protocol. It extends the ALTO Cost Map service and ALTO Property Map service so that the application can decide which endpoint(s) to connect based on not only numerical/ordinal cost values but also details 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. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-alto-path-vector/ No IPR declarations have been submitted directly on this I-D. _______________________________________________ alto mailing list [email protected] https://www.ietf.org/mailman/listinfo/alto
