Traffic Shaping and Priortization in ASA

Hi Everyone,

I  read that traffic prioritixation is always applied outbound direction when traffic is trying to leave the ASA.

Also i read that traffic Shaping can be applied to all outgoing traffic on a interface.

need to know if traffic shaping and priortization means same thing in ASA ?

There direction is always  outbound?

Traffic Shaping and Priortization in ASA

Hello Mahesh,

Not sure I get it but let me see if I can help,

Priority traffic: Basically allows you to split the interface into 2 different queues, one for low latency traffic and the other for best effor traffic. The one being on the Priority queue will always get served first.

Traffic Shapping:It's the buffering QoS techique that allows you to configure a limit of bandwith that you will provide to a certain traffic class, when you reach that limit the traffic that goes over the limit will be placed into a software queue, where it will be "holded". That's the different between traffic shapping and policing as whit traffic policing you will drop the offending traffic, with shapping you will hold it (so this is not good for Low latency traffic).

Now regarding the direction Traffic shapping can only be done on the outbound direction as queuing is an outbound process.

Hello Mahesh,

Queuing algorithms only work on the outbound direction.

Re: Traffic Shaping and Priortization in ASA

Hi Julio,

When i say prioritixation it means  on ASA

when we do

priority-queue inside

Then we apply class map for qos.

So in regards to the direction of traffic Priortization it is also only done in outbound direction.

So we can say that in regards to direction of traffic only they do the same job right?
