RSVP-TE

From Wikipedia, the free encyclopedia

Resource Reservation Protocol - Traffic Engineering

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 forth) of the packet streams they want to receive. RSVP runs on both IPv4 and IPv6. Also known as Resource Reservation Setup Protocol.

Traffic engineering extension to RSVP or RSVP-TE is detailed in IETF RFC 3209. RSVP-TE generally allows the establishment of label switched paths (LSPs), taking into consideration network constraint parameters such as available bandwidth and explicit hops. Operation overhead of RSVP-TE compared to the more widely deployed LDP based network will generally be higher. This is a classic trade-off between complexity and optimality in the use of technologies in telecommunications networks.
