Re: [ns] Dumb Policy

[Xuan Chen <xuanc@ISI.EDU>]

Hi,

I think what you need to do is to config two edge-to-core links between
the two sources and the aggregation node and give them different code
points (10 and 20 as you mentioned.). You can try to use dumb policy,
probably some modification may be necessary.

btw, some example scripts under ~ns/tcl/ex/diffserv may be helpful, they
use similar topology as yours.

Hope it helps,

I want to use Priority Queuing in the aggregation node, so that packets from one of the two sources receive a preferential treatment. How can I do that? I needn't use any kind of policy, such as token bucket. I just want the packets of source one to be policed, for example, as '10' , and the packets of the other source as '20' and then use two different queues. How can I do that? I've tried with Dumb Policy but, I don't think yo can select the DSCP value that way. Maybe there is a way of marking the packets at the source?
