The ISP and we are using the queue tree to manage QoS, our customers are configured as static and we mark packets and connections to assign bandwidth allowed in the queue tree, currently they I have more than 40 messages and every day the Mangles get bigger, some mangles stop working suddenly and this traffic will be an unspecified flow, how can I solve this problem ?, also What solution to provide better QO queuing tree
Well queue trees are a very very good choice for QOS for non simple setups.
Maybe there are some faults in your mangle rules thats why you think they stop to work ?
