QoS for Industrial Application

Hi there,

I´m studying QoS for industrial application, and the goal is to prioritize a traffic to a PLC (Programmable Logic Control) that communicates over Ethernet with UDP. The PLC is very sensitive to delay, jitters and packet losses. Also, we need to avoid any unnecessary traffic such as ARP requests from the network.

If anyone wish to help me and join this work, I starting the tests now where I have 4 3560 and 1 3750 (layer 3), and few more 2600 routers, and 2960-S switches for the lab.

Best Regards,

For your switches, you'll want to use the PQ feature.

For your routers, you'll want to use LLQ (and you may also want to minimize the size of your tx-ring).
