  • Optimal automated exploration of hierarchical multiprotocol label switching label switch paths
    Patent number: 8717936
    Abstract: Optimal automated exploration of hierarchical Multiprotocol Label Switching Label Switch Paths (MPLS LSPs) is disclosed. A path verification message (PVM) is transmitted from an initial router. Each label in the PVM's label stack corresponds to a hierarchy layer and is associated with a time-to-live (TTL) field. The TTL field for the label of a current layer is set so the PVM travels one hop from the initial router. In response, a reply message indicating that the PVM reached its destination is received.

  • Optimal automated exploration of hierarchical multiprotocol label switching label switch paths
    Patent number: 8116227
    Abstract: Optimal automated exploration of hierarchical MPLS LSPs is disclosed. A path verification message (PVM) is transmitted from an initial router. Each label in the PVM's label stack corresponds to a hierarchy layer and is associated with a time-to-live (TTL) field. The TTL field for the label of a current layer is set so the PVM travels one hop from the initial router. In response, a reply message indicating that the PVM reached its destination is received. These steps are then repeated. For each successive PVM transmitted, the TTL field associated with a label corresponding to the current hierarchy layer is incremented. For any reply message including information describing a non-current layer, modify the next PVM's label stack and increment the TTL field of the label for the described different layer; any other TTL fields are unchanged. If any received reply message indicates a destination router was reached, the process terminates.
