Qos where to apply

[quote=“nest”]You cannot control packets coming INTO your network. Think carefully - how can you stop a packet arriving? You cannot! There is no mechanism to tell the sender not to send them. All you can do is delay it, or drop it. But if you delay it, it has still arrived. Therefore you only really have control over what is leaving and the order of those packets, what is delayed, what is not.

So… if you have a CPE that can control QoS on an outgoing interface which is connected to your network, that is where you are able to control the packets leaving your client site. Once the packets are inside your network, it is too late.

Just to clarify are you referring to packets that are arriving from the internet to a network which is obivious you cannot contol,

My questions were to ask if some (?) QoS control can be achieved at the CPE using the RB boards (411+711), i am also aware that caution needs to be used with applying too much QoS at the CPE, as just one poor performance by a CPE cpu overloaded with tasks, can effect the overall performance of the AP and associated clients connected.

It would be great if the wireless connection of the CPE was disconnected if the CPE was maxed out by QoS and then it would not effect the AP only the customer?
