Method and systems for determining path of a virtual connection through a network

A method comprising:

• receiving, at a processing system, configuration data associated with devices in the network, the configuration data indicating how the devices have been configured;
• storing the configuration data in a non-transitory computer-readable medium for subsequent processing by the processing system;
• identifying, by the processing system, a virtual connection in the configuration data of a first endpoint from which data is communicated to a second endpoint;
• determining, by the processing system, a path of the virtual connection based on identifying a hop along the path based on a search of link layer information in the configuration data and identifying a next hop along the path based on a search of network layer information in the configuration data;
• and
• providing, by the processing system, a representation of the path of the virtual connection that indicates the hops in a computer-implemented model of the network for presentation on a display device.

A system comprising:

• an input configured to receive configuration data associated with devices in the network, the configuration data indicating how the devices have been configured;
• a non-transitory computer-readable medium that stores the configuration data for subsequent processing;
• and
• a processor configured to:
• identify a virtual connection in the configuration data of a first endpoint through which data is communicated to a second endpoint,
• determine a path of the virtual connection based on a search of one or more layers of information that comprises a first search of link layer configuration data and a contingent second search of network layer configuration data based on the first search, and
• output a representation of the path of the virtual connection that indicates the hops in a computer-implemented model of the network for presentation on a display device.

A method comprising:

• receiving configuration data associated with devices in the network, the configuration data indicating how the devices have been configured;
• storing the configuration data in a non-transitory computer-readable medium for subsequent processing;
• identifying a tunnel in the configuration data of a first endpoint from which encapsulated data is communicated to a second endpoint in the network;
• determining a physical path of the tunnel based on an assumed bi-directional symmetry for the tunnel between the first and second endpoints and a search of one or more layers comprising a first search of link layer data in the configuration data to identify a connection from a first hop to a second hop along the physical path;
• and a second search of network layer data in the configuration data when the first search fails to identify the connection from the first hop to the second hop;
• and
• providing a representation of the path of the tunnel that indicates the hops in a computer-implemented model of the network for presentation on a display device.
