Dear ALTO WG,

The latest version (-08) has improved the clarity of the algorithms with 
simpler symbols and more detailed examples. Reviews and comments are 
welcomed!

Best Regards,

Kai

Abstract:
    The path vector extension [I-D.ietf-alto-path-vector] has extended
    the base ALTO protocol [RFC7285] with the ability to represent a more
    detailed view of the network which contains not only end-to-end costs
    but also information about shared bottlenecks.

    However, the view computed by straw man algorithms can contain
    redundant information and result in unnecessary communication
    overhead.  The situation gets even worse when certain ALTO extensions
    are enabled, for example, the incremental update extension
    [I-D.ietf-alto-incr-update-sse] which continuously pushes data
    changes to ALTO clients.  Redundant information can trigger
    unnecessary updates.

    In this document, several algorithms are described which can
    effectively reduce the redundancy in the network view while still
    providing the same information as in the original path vectors.


                                                                                   


Please note that it may take a couple of minutes from the time of submission
until the htmlized version and diff are available at tools.ietf.org.
