Is there a device or piece of software that can act as a transparent Ethernet bridge and limit bandwidth on MAC by MAC basis?

So for example, it will only let a particular MAC address on side A use 100kbps in ether direction.

    You can configure a Linux bridge with ebtables to mark the packets and tc to shape the traffic.

    Also some Cisco switches can do bandwidth limiting. See Cisco:Comparing Traffic Policing and Traffic Shaping for Bandwidth Limiting

  2. Untangle can do this via the paid bandwidth control app.

  3. I typically use dummynet in FreeBSD (picoBSD, really) on a floppy or bootable USB token (or in a Virtual Machine) to do this. But you can also do it with iptables in Linux, some configurable switches, and specialty devices like this one or other WAN/LAN emulators.

  4. Another solution - m0n0wall, designed to test latency in applications which work over network.
