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 : Content Delivery Network Interconnection (CDNI) Request Routing: CDNI Footprint and Capabilities Advertisement using ALTO Authors : Jan Seedorf Y.R. Yang Kevin J. Ma Jon Peterson Jingxuan Jensen Zhang Filename: draft-ietf-alto-cdni-request-routing-alto-12.txt Pages : 41 Date: 2020-07-13 Abstract: The Content Delivery Networks Interconnection (CDNI) framework [RFC6707] defines a set of protocols to interconnect CDNs, to achieve multiple goals such as extending the reach of a given CDN to areas that are not covered by that particular CDN. One component that is needed to achieve the goal of CDNI described in [RFC7336] is the CDNI Request Routing Footprint & Capabilities Advertisement interface (FCI). [RFC8008] defines precisely the semantics of FCI and provides guidelines on the FCI protocol, but the exact protocol is explicitly outside the scope of that document. This document defines an FCI protocol using the Application-Layer Traffic Optimization (ALTO) protocol, following the guidelines defined in [RFC8008].

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.

Richard Yang Jingxuan Jensen Zhang Kai Gao Filename: draft-ietf-alto-unified-props-new-12.txt Pages : 55 Date: 2020-07-13 Abstract: This document extends the Application-Layer Traffic Optimization (ALTO) Protocol [RFC7285] by generalizing the concept of "endpoint properties" to generic types of entities, and by presenting those properties as maps, similar to the network and cost maps in [RFC7285].

[alto] I-D Action: draft-ietf-alto-performance-metrics-12.txt
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 Performance Cost Metrics Authors : Qin Wu Y. Richard Yang Young Lee Dhruv Dhody Sabine Randriamasy Luis Miguel Contreras Filename: draft-ietf-alto-performance-metrics-12.txt Pages : 32 Date: 2020-07-13 Abstract: Cost metric is a basic concept in Application-Layer Traffic Optimization (ALTO), and is used in basic ALTO services including both the cost map service and the endpoint cost service. Different applications may use different cost metrics, but the ALTO base protocol [RFC7285] defines only a single cost metric, i.e., the generic "routingcost" metric; see Sec. 14.2 of [RFC7285]. Hence, if the ALTO client of an application wants to issue a cost map or an endpoint cost request to determine the resource provider that offers better delay performance (i.e., low-delay) to a resource consumer, the base protocol does not define the cost metric to be used. This document addresses the issue by introducing network performance metrics, including network delay, jitter, packet loss rate, hop count, and bandwidth. The ALTO server may derive and aggregate such performance metrics from routing protocols such as BGP-LS, OSPF-TE and ISIS-TE, or from end-to-end traffic management tools, and then expose the information to allow applications to determine "where" to connect based on network performance criteria. There are multiple sources to derive the performance metrics. For example, whether the metric reported is an estimation based on measurements or it is a service-level agreement (SLA) can define the meaning of the performance metric. Hence, an application may need additional contextual information beyond the metric value. This document introduces an additional "cost-context" field to the ALTO "cost-type" field to convey such information.

[alto] Update of recharter discussions
Dear ALTOers, Despite during a slow summer, the team had excellent discussions on ALTO recharter. We understand that we will switch to this WG mailing list for more discussions, but we also find that face-2face discussions in zoom meetings appear to be a bit faster, and we sure will switch to the mailing list for more open discussions soon. Please this Google document for some updates: https://docs.google.com/document/d/1qP9jf-CMXvNiEE3YAnApTczAE4QkBW23Q1Eg99uOaEQ/edit?usp=sharing In particular, the document has a Potential Topics part, Please kindly take a look and feel free to edit. Please also take a look at the Topic Discussion Log. It is just getting started to keep some log, but it is already may be of some interest. Cheers, Richard ___ alto mailing list alto@ietf.org https://www.ietf.org/mailman/listinfo/alto
