[KLUG Members] Bandwidth throttling

[Randall Perry]

What is the best way to control bandwidth useage?
Scenario 1:
Office with DSL connection shared by 2 IP networks (192.168.10.x/24 and
192.168.11.x/24)

Scenario 2:
T1 trunk shared by 5 IP networks (172.16.x.x/16, 172.17.x.x/16,
172.18.x.x/16, 172.19.x.x/16, 172.20.x.x/16)

Would I then want to put a proxy server on each segment (so their own
bandwidth is not used unnecessarily)?

TIA
