Looking for suggestions here.   Essentially I am trying to pin down latency as an affect on a specific application,

Anyway, I have a bench network with a couple of nodes, and I want to introduce latency between the Nodes.  I have a couple of options on hardware at my disposal (HP and Enterasys full L3 switches, as well as an older Nortel L3 router).    Also all kinds of pc hardware.  

I was thinking of just creating a L2 loop, but I feel that there is wuite a lack of control at that point

Most Linux kernels today have netem (network emulation) compiled in by default.

You can get a PC with two NIC's, create a bridge and then use netem to control all kinds of network related things:  bandwidth, jitter, packet loss, latency.

You can read this post for more information and links on the subject:
