  • Method and system for topology construction and path identification in a two-level routing domain operated according to a simple link state routing protocol
    Patent number: 7120120
    Abstract: A method and system for extracting and building end-to-end route information in a two-level, multi-area Internet protocol (IP) autonomous system (AS) operated according to a simple link state routing protocol such as the Integrated System to Integrated System (IS-IS) protocol is disclosed. The method and system enables a user, such as a network administrator, to explicitly identify a full set of paths (links and routers) that a given IP packet would potentially traverse from its entry point in the area of the AS where it originates until its exit point in its intended destination or exit area.

  • Method and system for path identification in packet networks
    Patent number: 6836465
    Abstract: A method and system for extracting and building end-to-end route information in a multi-area Internet protocol (IP) autonomous system (AS) is disclosed. The method and system enable a user, such as a network administrator, to explicitly identify a full set of paths (links and routers) that a given IP packet would potentially traverse from its entry point in the source area of the AS where it originates until its exit point in its intended destination area.
