In certain networks, it is critical to consider network performance
criteria when selecting the path for an explicitly routed RSVP-TE
Label Switched Path (LSP).  Such performance criteria can include
latency, jitter, and loss or other indications such as the
conformance to link performance objectives and non-RSVP TE traffic
load.  This specification describes how a path computation function
may use network performance data, such as is advertised via the OSPF
and IS-IS TE metric extensions (defined outside the scope of this
document) to perform such path selections.

This document is a product of the Traffic Engineering Architecture and Signaling Working Group of the IETF.
