Computer network control plane tampering monitor

DWPI Title: Computer-implemented path monitoring method for establishment of label-switched path (LSP) involves generating notification, responsive to determining whether message units produce expected pair of values of information field
Abstract: A computer network control plane tampering monitor that detects unauthorized alteration of a label-switched path setup for an information packet intended for transmission through a computer network.
Use: Computer-implemented path monitoring method for monitoring the establishment of a label-switched path through a global domain of label-switched nodes, such as, for example label-switched routers (LSRs).
Advantage: Performs tamper detection for an entire global domain of Label Switch Routers and other types of nodes while eliminating the need to implement costly link-by-link encryption. Provides efficient real-time monitoring capability with a single monitoring platform for processing economy. Eliminates the need for reliance on secure physical protection mechanisms located on individual Label Switch Router platforms. Information that has been subjected to tampering by a man-in-the-middle agent is quickly detected and the system administrator can be notified.
Novelty: The path monitoring method involves generating a first message unit (22) including a path identifier and at least one information field; generating a second message unit within a node (20) along the path through the computer network; and generating a notification (40), responsive to determining whether the first message unit and the second message unit produce an expected pair of values of the at least one information field. The second message unit includes the path identifier and path summary comprising the information field.
