  • QoS routing;
  • ATM signaling;
  • user-to-network (UNI) signaling;
  • private network-network Iinterface (PNNI) signaling;
  • integrated services;
  • selection of metrics;
  • weighted graph model;
  • path selection;
  • Bellman-Ford algorithm;
  • Dijkstra algorithm


Chapter 8 covers the topic of QoS routing, which is the process of selecting a path for a new connection based on its QoS requirements and network resources. The chapter starts with an introduction to QoS signaling and routing in ATM networks and includes a discussion of private network-to-network interface (PNNI) signalling. QoS routing over IP networks is also covered. Several path selection algorithms are presented.
