Colleagues, We just published a new version of draft-jenkins-alto-cdn-use-cases, which is available here: http://tools.ietf.org/html/draft-jenkins-alto-cdn-use-cases-01 The draft is the result of working with the authors of draft-penno-alto-cdn to merge the use cases in that draft with the use cases already in draft-jenkins-alto-cdn-use-cases-00. Some editorial changes have been made and 3 additional use cases are described: 1) Exposing NSP End User Reachability to a CDN 2) Exposing CDN End User Reachability to CSPs 3) CDN acquiring content from multiple upstream sources Ben Begin forwarded message: > On 17/06/2011 14:05, "internet-drafts@ietf.org" <internet-drafts@ietf.org> > wrote: > >> A new version of I-D, draft-jenkins-alto-cdn-use-cases-01.txt has been >> successfully submitted by Ben Niven-Jenkins and posted to the IETF >> repository. >> >> Filename: draft-jenkins-alto-cdn-use-cases >> Revision: 01 >> Title: Use Cases for ALTO within CDNs >> Creation date: 2011-06-17 >> WG ID: Individual Submission >> Number of pages: 14 >> >> Abstract: >> For some time, Content Distribution Networks (CDNs) have been used in >> the delivery of some Internet services (e.g. delivery of websites, >> software updates and video delivery) as they provide numerous >> benefits including reduced delivery cost for cacheable content, >> improved quality of experience for end users and increased robustness >> of delivery. >> >> In order to derive the optimal benefit from a CDN it is preferable to >> deliver content from the servers (caches) that are "closest" >> to the >> End User requesting the content, where "closest" may be as >> simple as >> "geographical or network distance" combined with CDN server >> load >> within a location, but may also consider other more complex >> combinations of metrics and CDN or Network Service Provider (NSP) >> policies. >> >> There are a number of different ways in which a CDN may obtain the >> necessary network topology and/or cost information to allow it to >> serve End Users from the most optimal servers/locations, such as >> static configuration, passively listening to routing protocols >> directly, active probing of underlying network(s), or obtaining >> topology and cost by querying an information service such as the ALTO >> map & cost services. >> >> This document describes the use cases for a CDN to be able to obtain >> network topology and cost information from an ALTO server(s). >> >> >> >> >> >> The IETF Secretariat >
