It depends per what direction you want to control.
If you want, e.g. limit outbound traffic, then
running DS/QoS tools at your Linux box is just fine.
If you want your INBOUND traffic controlled, then the
box at the other end of your link must do the DS/QoS.

QoS and/or fair queueing
CONFIG_NET_SCHED
When the kernel has several packets to send out over the network
devices, it has to make a decision which one to send first. This is
especially important if some of the network devices are real time
devices that need a certain minimum data flow rate. There are
several different algorithms for how to do this "fairly"; they are
called packet schedulers. If you want to stick to the default
scheduling algorithm, say N here. If you want to experiment with a
couple of different algorithms, say Y. You can then attach different
schedulers to different network devices. Currently, this is only
recommended for experts.
To administer these schedulers, you'll need the user-level utilities
from the package iproute2+tc at ftp://ftp.inr.ac.ru/ip-routing/
If you say Y here and to "/proc filesystem" below, you will be able
to read status information about priority schedulers from the file
/proc/net/psched.
The available schedulers are listed in the following questions; you
can say Y to as many as you like. If unsure, say N now.
Instead of that site in Russian, do go to:
ftp://ftp.src.uchicago.edu/pub/linux/ip-routing/
ftp://ftp.funet.fi/pub/mirrors/ftp.inr.ac.ru/ip-routing/ (STM1 to EUR/USA)

I believe you are interested about QoS at the limited
EXTERNAL connection bandwidth, not your local LAN ?
