When setting up a Label Switched Path (LSP) in Generalized MPLS
(GMPLS) and MPLS Traffic Engineering (MPLS-TE) networks, the
completion of the signaling process does not necessarily mean that
the cross-connection along the LSP has been programmed accordingly
and in a timely manner.  Meanwhile, the completion of the signaling
process may be used by LSP users or applications that control their
use as an indication that the data path has become usable.  The
existence of the inconsistency between the signaling messages and
cross-connection programming, 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 way in which LSPs
are used and to make applications or tools that depend on and use
LSPs more robust.  This document defines a series of performance
metrics to evaluate the connectivity of the data path in the
signaling process.  [STANDARDS-TRACK]
