Scanning

Scanning is the key step of discovery process that performs the actual detection of services available on network hosts.

Given a particular address, Iotellect Network Manager checks availability of the services selected for the discovery. This is called an single-host scanning task. It comprises the two steps:

  • Checking Ping service. ICMP Echo Requests are used to test device availability. If the device correctly responds to the ping requests, we deem the device as available ("alive"), and continue with the next step of scanning. Otherwise, depending on the value of Discover Ping-Failed Devices parameter we either (if the Discover Ping-Failed Devices parameter is set to true) go to the next step, or just consider the device unavailable skipping the next step (if the Discover Ping-Failed Devices is false).
  • Checking other services. The system tries to detect the availability of every service selected for discovery.

    • Note, that the overall scanning process is limited by Maximum Total Discovery Time, while single-host scanning tasks are limited by Maximum Single Host Discovery Time.
