RE: Router with bandwidth management
Title: Message
Well,
if you choose to go with Cisco, they support some form of bandwidth management
called rate-limiting.
With
rate-limiting, you can asign minimum, maximum and burst bandwidth to a specific
IP address and/or network range. Here's a sample
configuration:
conf
t
access-list 100 remark 32Kbps to Wireless Client
XXX
access-list 100 permit ip host 192.168.0.200
any
access-list 100 permit ip any host
192.168.0.200
int e0/0
rate-limit input access-group 100 32000 8000 16000 conform-action transmit
exceed-action drop
rate-limit output access-group 100
32000 8000 16000 conform-action transmit exceed-action drop
As you
can see above, the access list that matches your wireless client's IP address is
placed onto the Ethernet interface that is connected to your wireless segment.
In the rate-limit statement on the Ethernet interface, 32000 is the bits per
second allowed, 8000 is the normal burst bytes and 16000 is the maximum burst
bytes. As the last few lines say, if the user's IP address conforms to this
setting, transmit his packets through. If the assigned capacity is exceeded,
begin to apply congestion control - basically, drop packets exceeding allocated
capacity.
Rate-limiting is supported on only the 2600 series
chassis and above. From experience, it doesn't work on the 1600 nor the 1700
series Cisco routers.
