Longest Response Time

Overview

• Indicates the longest time between a request and a corresponding response in the entire capture.

Why it fails

• The router is busy/overloaded
• There are too many hops (too many routers in between the requesting device and the responding device)
• The network is congested
• The destination controller is busy

How to fix it

• Identify the path between the requesting and responding device for each slow response time (using your network drawing)
• Look at those routers in the BACnet browser and figure out what traffic is passing through them
• Check the responding device, see if the device is busy.
