There is 5 users sharing one DSL connection to Internet (640kbps) with C1721 (IOS12.4), Eth0 WAN FastEth0 LAN. How to dynamically shape banwidth to each user, depending on number users connected to LAN? For instance, if there is 2 users they should have
320kbps each, if there is four - 160 each. How to do it?rzirzi
No one know how to do it?
With such a small sample of users the router will jsut end up giving bandwidth to whoever is talking to it. Shaping is most uselfel when there are lots of users. Even if five users hit it at the same time with a big download, the user with the fastest pc would likely get a slighlty bigger chunk.
CIsco has fair wieght queueing and such, but queue algorithms often balance FLOWs not IP addresses. So if one user kicks off 10 downloads, then he'll get 10 portions of the circuit.

So, how to resolve my problem, to share bandwidth evenly on LAN??

Aside from the difficulty of adjusting bandwidth allocations based on the number of users, I suspect you have a far larger problem. If this is a typical DSL setup, the heavy bandwidth usage is the traffic coming from the DSL provider into your router. By the time the traffic gets to your router, the delays have already occurred. For some classes of applications, traffic appliances can be used to control the flows by regulating the acknowledgements heading back out to the sources on the Internet, but you won't find that level of application knowledge implemented on typical routers. Also, depending on the applications, you may benefit from local cacheing, such as Squid.
Good luck and have fun!
