Resource Reservation Protocol

Resource Reservation Protocol (RSVP) is a signaling protocol that handles bandwidth allocation and true traffic engineering across an MPLS network. Like LDP, RSVP uses discovery messages and advertisements to exchange LSP path information between all hosts. However, RSVP also includes a set of features that control the flow of traffic through an MPLS network.
