RSVP-TE

Resource Reservation Protocol - Traffic Engineering (RSVP-TE) is an extension of the Resource Reservation Protocol (RSVP) for traffic engineering. It 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.

RSVP-TE generally allows the establishment of Multiprotocol Label Switching (MPLS) label-switched paths (LSPs), taking into consideration network constraint parameters such as available bandwidth and explicit hops.[1]
