RPR: Restore Path Request

Restore Path Request (RPR) is a WaRP request sent using a Restore Path packet that is used to establish a virtual path between two nodes over an optical link. The request is sent by a source node, or a proxy source node, to establish an intra-zone path for a Virtual Wavelength Path (VWP). The packet usually is sent during failure recovery procedures but also can be used for provisioning new VWPs. The node that sends the request is called the originating node. The node that terminates the request is called the target node.
