Introduction
Segregating | The best method to protect Quantum Automation traffic from information systems |
Traffic | traffic is to provide a completely separate physical network for automation control. |
| Another method is to use readily available Ethernet devices such as bridges and |
| routers to logically segment the network, isolating office traffic from control data. |
Minimizing | Components such as repeaters, bridges, routers and hubs take a finite time to |
Delays | process each message. If messages pass through many of these devices, |
| processing delays will accumulate. Delay times are available from device |
| manufacturers. Check with your network administrator to quantify the effect on |
| control messages and to determine whether it will be significant for your |
| application. |
Using Switches | Ethernet switches can be used to ensure higher network performance. These |
| newer devices allow each connection to have access to the full 10 Mbps bandwith |
| instead of having to share the bandwith with all other nodes. They reduce the |
| timing problems associated with Ethernet collisions and the resulting “back off” |
| transmission delays. Check with your network administrator to see if your |
| application would benefit from switching Ethernet devices. |
