In this case, it appeared to be a customer's edge router, not a
core/backbone router...although those did seem to have rather high latency
(400ms and higher in some cases) and high packet loss (about 18-20%).

I'm impressed that the routers have sufficient buffer memory to do that.


That is what buffer bloat is all about -- too much queue and too little
circuit.
