   When setting up a label switched path (LSP) in Generalized MPLS and
   MPLS/TE networks, the completion of the signaling process does not
   necessarily mean that the cross connection along the LSP have been
   programmed accordingly and in a timely manner.  Meanwhile, the
   completion of signaling process may be used by applications as
   indication that data path has become usable.  The existence of this
   delay and the possible failure of cross connection programming, if
   not properly treated, will result in data loss or even application
   failure.  Characterization of this performance can thus help
   designers to improve the application model and to build more robust
   applications.  This document defines a series of performance metrics
   to evaluate the availability of data path in the signaling process.
