Shaping and Flow control capability of Linux TC ?

Shaping and Flow control capability of Linux TC ?

[SunilVasanta]

Hi Folks,

I'm new to linux TC and trying to develop PCEF(Policy control and 
Enforcement Functionality)  module using Linux TC feature [ on a COTS 
hardware] .

In this regard I started testing in my LAN and I'm able to control 
bandwidth for 10 machines using Linux TC. Now I want to take it it 
further by using TC for controlling large number of flows/machines .

Before investing time and resource on this activity, I have some questions.

My question to community is that "CAN TC BE USED TO SHAPE LARGE NUMBER 
OF FLOW say around 10k", is there any known limitation ?

Anyone used TC to control large number of flows ?

I have gone through lot of open source materiel available on net but 
almost all doc's talk about controlling  very limited number of flows 
and  emphasis more on Qdisc.


Many Thanks,
sunil

Yes, I have personally seen setups with 10k+ flows, 3000 devices and 
around 500k conntrack entries.
