Implementing Rsvp For Mpls-Te And Mpls O-Uni - Cisco CRS Configuration Manual

Implementing RSVP for MPLS-TE and MPLS
O-UNI
The Multiprotocol Label Switching (MPLS) is a standards-based solution, driven by the Internet Engineering
Task Force (IETF), devised to convert the Internet and IP backbones from best-effort networks into
business-class transport media.
Resource Reservation Protocol (RSVP) is a signaling protocol that enables systems to request resource
reservations from the network. RSVP processes protocol messages from other systems, processes resource
requests from local clients, and generates protocol messages. As a result, resources are reserved for data
flows on behalf of local and remote clients. RSVP creates, maintains, and deletes these resource reservations.
RSVP provides a secure method to control quality-of-service (QoS) access to a network.
MPLS Traffic Engineering (MPLS-TE) and MPLS Optical User Network Interface (MPLS O-UNI) use
RSVP to signal label switched paths (LSPs).
