Performance-Based Path Selection for Explicitly Routed Label Switched Paths (LSPs) Using TE Metric Extensions
A. Atlas, J. Drake, S. Giacalone, Stefano Previdi · 2016
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.
