Discovering device connectivity

The discovery of device connectivity is carried out in several steps.

The following figure shows how device connectivity is discovered, as well as how devices are discovered recursively.

Concept diagram that describes the process flow for the discovery of device connectivity

The following process flow describes Figure 1:

  •  1 : When information is inserted into the despatch table of a discovery agent, the agent attempts to discover the connectivity information for that device. The agent sets up a TCP socket-based communication link with the Helper Server and requests the appropriate connectivity information.
  •  2 : A stitcher passes the addresses of the remote neighbors of the device, and the subnet address or addresses of the device, to a finder for discovery. Because these addresses might not exist, and also might not be in the specified discovery scope, the addresses must run through the discovery process from the beginning.
