The IESG has approved the following document: - 'Content Delivery Network Interconnection (CDNI) Request Routing: CDNI Footprint and Capabilities Advertisement using ALTO' (draft-ietf-alto-cdni-request-routing-alto-22.txt) as Proposed Standard This document is the product of the Application-Layer Traffic Optimization Working Group. The IESG contact persons are Zaheduzzaman Sarker and Martin Duke. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-alto-cdni-request-routing-alto/ Technical Summary The Content Delivery Networks Interconnection (CDNI) framework 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 CDNI framework is the CDNI Request Routing Footprint & Capabilities Advertisement interface (FCI). RFC 8008 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 RFC 8008. Working Group Summary The WG process was not contentious. Document Quality There is one known implementation in progress. As with all ALTO extensions, there are experiments, but still uncertainty about whether the base protocol will see wide deployment. In particular, the CDNI use case is perceived to be much more promising than the initial target, peer-to-peer networks. Personnel Vijay K. Gurbani is the document shepherd. Martin Duke is the Area Director.
