Cisco Cisco IOS Software Release 12.2(33)SRE

admission control—The process by which an RSVP reservation is accepted or rejected on the basis of 
end-to-end available network resources.

bandwidth—The difference between the highest and lowest frequencies available for network signals. 
The term is also used to describe the rated throughput capacity of a given network medium or protocol.

message pacing—A system for managing volume and timing that permits messages from multiple 
sources to be spaced apart over time. RSVP message pacing maintains, on an outgoing basis, a count of 
the messages that it has been forced to drop because the output queue for the interface used for the 
message pacing was full.

MP—merge point. The node where the new and old FLR segments meet.

PLR—point of local repair. The node that initiates an FLR procedure.

QoS—quality of service. A measure of performance for a transmission system that reflects its 
transmission quality and service availability.

RSVP—Resource Reservation Protocol. A protocol that supports the reservation of resources across an 
IP network. Applications running on IP end systems can use RSVP to indicate to other nodes the nature 
(bandwidth, jitter, maximum burst, and so on) of the packet streams that they want to receive.
