>   Because one MPLS label only identifies one single flow on a link
>   between two MPLS routers, information related to one MPLS label is
>   exchanged only between (physically and logically) neighbour routers.
>   In other words, MPLS label have a link-local significance on which
>   two neighbour routers have previously agreed on.  It is therefore not
>   a trivial task for a network operator to know where a flow is going
>   as it implies to retreive the MPLS labels mappings on each hops in
>   order to get a complete view of end-to-end LSP paths.  This taks is
>   even harder when it comes to get the MPLS label mappings over time in
>   a purpose of monitoring and/or troubleshooting network services.
>
>   This document thus defines a new method to monitor MPLS label
>   mappings that collects and stores MPLS labels mapping information so
>   as to offer to one IP/MPLS network operator a reliable and clear view
>   of its network LSPs end-to-end establishment over time while
>   minimising the impact on network convergence and router CPU.
