“…The study of stability on networks with fixed bi-modal link capacities [43,44] started the way towards the consideration of networks with more dynamic properties and behaviors. In the latest decade, that research line was exhaustively studied (see, e.g., [39,40,41,42]). Probably, the most significant conclusions of those works are, that the stability properties of fifo networks are not preserved when fifo is composed with ntg, and that some packet-trajectory variations of the property of stability can be fully characterized when compositions of ntg with other specific protocols are considered.…”
