Table 50: MPLS Terms and Acronyms (continued)
DefinitionTerm
Resource Reservation Protocol enhanced to support MPLS traffic
engineering; E Series routers support RSVP-TE
RSVP-TE
The portion of the LSP from one LSR to another LSR in a
point-to-multipoint tunnel.
Sub-LSP
The ability to control the path taken through a network or portion of
a network based on a set of traffic parameters (bandwidth, QoS
parameters, and so on). Traffic engineering (TE) enables
performance optimization of operational networks and their
resources.
Traffic engineering
LSP that is used by an IGP to reach a destination, or an LSP that uses
traffic engineering
Tunnel
