I have been asked to document and verify QoS solutions in our network. We are multinational big company with Hundred branches world wide. As I am new in such field, I usually work with SDN, is there any software to document such data?
DSCP values for each class of service at each point in the network. WLAN, LAN, WAN (different providers).
Enforcement of marking (where is classification taking place) local client, access switch, wan router etc...
Queues information for different devices which means buffer sizes and thresholds etc..
It doesnt matter if the software is opensource or commercial. what is important:
document these settings allow engineers during troubleshooting.
