Subject: [LARTC] Changing Linux traffic control parameters on the fly
Date: Fri, 28 Mar 2003 15:12:14 +0000	[thread overview]
Message-ID: <marc-lartc-104886443613956@msgid-missing> (raw)

Hi all,

I'm executing some experiments in a test network and I have a doubt. It 
is possible to change linux traffic control parameters (say, for 
example, the bandwidth allocated to a flow, its ceiling rate in a HTB 
scheduler, its weight parameter in a CBQ scheduler and so on) while the 
flow is actually traversing a router?

An example: let's assume that a certain class has allocated a bandwidth 
of 500 kbit/sec. Can I change, say after 10 seconds, while the flow is 
still active, the bandwidth allocated to that class to 1 Mbit/sec?

I know there is the command tc qdisc change with which I can change the 
parameters for a qdisc, but how to use it? Launching after 10 seconds 
another tc script?
Any ideas?
Thank you,

	Simone.
