We at ESS are using CA gateways in a “chain” configuration, i.e., roughly in the following way:
Machine (aka Technical) network -> gateway A-> internal DMZ -> gateway B-> office network.
 
Does any of you have any experience with such a configuration?


Hi Timo—

For the SNS beam lines, each beam line has a gateway, and then we have a gateway-of-gateways for office machine clients to connect with . . .

bl1-gateway  }
bl2-gateway  }
bl3-gateway  }   -> aggregating-gateway -> office network clients
. . .                }
bln-gateway  }


There are nearly 30 gateways at the first level on separate private networks. Large arrays can impact performance, but generally it has worked quite well. We do not see a 1 second delay.
