We present a survey of traffic models for communication networks whose key performance indicators like blocking probability and mean delay are independent of all traffic characteristics beyond the traffic intensity. This insensitivity property, which follows from that of the underlying queuing networks, is key to the derivation of simple and robust engineering rules like the Erlang formula in telephone networks.
