        Title           : Decoupled/Hierarchical VPLS: Commonalities and 
                          Differences

This draft describes commonalities and differences between decoupled 
and hierarchical architectures to support scalable Virtual Private 
LAN Services (VPLS). The need to maintain a full mesh of control 
connections (e.g. LDP, BGP, etc�) and transport paths between all PEs 
that are service aware may impose a scalability limit on the non 
decoupled VPLS architecture.

NOTE:   The mail server at ietf.org can return the document in
        MIME-encoded form by using the "mpack" utility.  To use this
        feature, insert the command "ENCODING mime" before the "FILE"
        command.  To decode the response(s), you will need "munpack" or
        a MIME-compliant mail reader.  Different MIME-compliant mail readers
        exhibit different behavior, especially when dealing with
        "multipart" MIME messages (i.e. documents which have been split
        up into multiple messages), so check your local documentation on
        how to manipulate these messages.
                
                
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
