RSVP MPLS (Resource Reservation Protocol with Multiprotocol Label Switching) is a protocol used in computer networking to establish and maintain paths for data transmission across a network.

MPLS is a mechanism used in routers to efficiently route packets across a network. It involves adding a short label to each packet, which allows routers to quickly identify the path that the packet should take through the network.

RSVP is a signaling protocol that is used to request and reserve resources along a path in a network. It enables network nodes to request specific quality of service (QoS) parameters, such as guaranteed bandwidth or low latency, from the network.

When RSVP is combined with MPLS, it allows for the creation of traffic-engineered paths through the network. This means that traffic can be routed along specific paths that have been reserved for it, rather than being sent along the default path. This can help to improve network performance and reduce congestion.

Overall, RSVP MPLS is a powerful technology that enables network operators to provide QoS guarantees for their customers and optimize their network performance.
