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 Working Group of the IETF. Title : ALTO Protocol Author(s) : Richard Alimi Reinaldo Penno Y. Richard Yang Filename : draft-ietf-alto-protocol-14.txt Pages : 75 Date : 2013-02-25 Abstract: Applications using the Internet already have access to topology information of Internet Service Provider (ISP) networks. For example, views to Internet routing tables at looking glass servers are available and can be practically downloaded to many application clients. What is missing is knowledge of the underlying network topologies from the point of view of ISPs (henceforth referred as Providers). In other words, what a Provider prefers in terms of traffic optimization -- and a way to distribute it. The Application-Layer Traffic Optimization (ALTO) Service provides network information (e.g., basic network location structure and preferences of network paths) with the goal of modifying network resource consumption patterns while maintaining or improving application performance. The basic information of ALTO is based on abstract maps of a network. These maps provide a simplified view, yet enough information about a network for applications to effectively utilize them. Additional services are built on top of the maps. This document describes a protocol implementing the ALTO Service. Although the ALTO Service would primarily be provided by the network operator (e.g., an ISP), content service providers and third parties could also operate this service. Applications that could use this service are those that have a choice to which end points to connect. Examples of such applications are peer-to-peer (P2P) and content delivery networks.
