We put together a first iteration of a very simple ALTO solution  
draft.  We hope this will be useful as an example point in the  
solutions space and thus allow to refine the requirements document and  
the problem statement.



    The ALTO Information Export Service is a simple way to convey ISP
    routing policy preferences to applications.  Applications that could
    use this service are those that have a choice in connection
    endpoints.  Examples of such applications are peer-to-peer and
    content delivery networks.

    Applications already have access to great amount of underlying
    topology information.  For example, views of the Internet routing
    table are easily available at looking glass servers and entirely
    practical to download to every client.  What is missing is the
    routing policy information -- what does the local ISP actually

    This document describes a very simple mechanism that would allow to
    export such information to applications.  While such service would
    primarily be provided by the network, i.e., the local ISP, third
    parties could also operate this service.
