Abstract Abstract
In certain networks, it is critical to consider network performance In certain networks, it is critical to consider network performance
criteria when selecting the path for an explicitly routed RSVP-TE criteria when selecting the path for an explicitly routed RSVP-TE
LSP. Such performance criteria can include latency, jitter, and loss LSP. Such performance criteria can include latency, jitter, and loss
or other indications such as the conformance to link performance or other indications such as the conformance to link performance
objectives and non-RSVP TE traffic load. This specification uses objectives and non-RSVP TE traffic load. This specification uses
network performance data, such as is advertised via the OSPF and ISIS network performance data, such as is advertised via the OSPF and ISIS
