Hi, we have updated the ALTO requirements draft. There is only one significant change to the content: A new requirement related to the scalability of the ALTO solution:
REQ. ARv05-29: The ALTO client protocol SHOULD allow the ALTO server to specify a "target audience" in an ALTO reply. This is a set of resource consumers (expressed, e.g., as a list of host group descriptors). The guidance provided in the respective ALTO reply can be used and possibly re-used during the specified lifetime by or for the resource consumers in the "target audience". Re-using may include redistributing the ALTO reply to other parties in the specified set, as well as using the same ALTO information in a resource directory to improve the replies to different resource consumers.

This draft is a work item of the Application-Layer Traffic Optimization Working Group of the IETF. Title : Application-Layer Traffic Optimization (ALTO) Requirements Author(s) : S. Kiesel, et al. Filename : draft-ietf-alto-reqs-05.txt Pages : 27 Date : 2010-06-14 Many Internet applications are used to access resources, such as pieces of information or server processes, which are available in several equivalent replicas on different hosts. This includes, but is not limited to, peer-to-peer file sharing applications. The goal of Application-Layer Traffic Optimization (ALTO) is to provide guidance to applications, which have to select one or several hosts from a set of candidates, that are able to provide a desired resource. This guidance shall be based on parameters that affect performance and efficiency of the data transmission between the hosts, e.g., the topological distance. The ultimate goal is to improve performance (or Quality of Experience) in the application while reducing resource consumption in the underlying network infrastructure. This document enumerates requirements for ALTO, which should be considered when specifying, assessing, or comparing protocols and implementations, and it solicits feedback and discussion.
