Hello, Thank you for your post here. To make us have a clear understanding of your questions, could you please explain more about "measuring a distence between the two systems of a network"? Do you mean the network isolation such as IPSec and 802.1X? If you have any questions or concerns, please do not hesitate to let us know.
