Abstract

An apparatus for zone routing, comprising a transmitter, a receiver, and a processor coupled to the transmitter and the receiver, wherein the processor is configured to determine a path through a network, wherein the path extends from an ingress edge node of the network to a first egress edge node of the network, obtain a global identifier (ID) for identifying a label-switched path (LSP) along the path, send, via the transmitter, a first LSP creation request message to the first egress edge node requesting creation of the LSP, wherein the first LSP creation request message comprises the global ID, and receive, via the receiver, a LSP creation response message from the ingress edge node indicating a creation status of the LSP in response to the first LSP creation request message.
