In queueing networks with alternate paths, the ability of customers leaving a node to use arcs to move ahead of customers not taking those arcs so as to arrive at a subsequent node ahead of customers they were previously behind. This can also occur for customers on the same path if a visited node has multiple servers, since a customer who started service later than other customers there could be served more quickly and thus pass some of those other customers.
