Keywords:

  • QoS realm, and Quality of Service (QoS) - always in a world of its own;
  • QOS usage, increasing to a point - a necessary part of network design and operation;
  • large-scale deployments, technology becoming mature - QOS, being no exception;
  • voice traffic, supported on circuit-switched networks - delivered on “same common” packet-switched infrastructure;
  • inherent drawback, in a common network - the road, being now the same for different traffic types;
  • different types of traffic - and different requirements;
  • key point with QOS, non-equal split of resources - implying no “win–win” situations;
  • QoS role, application of different network behaviors - to different traffic types;
  • QOS concept, hard to grasp - structurally different from other concepts in networking world;
  • standards and Per-Hop Behavior - standards in IP realm, relevant to QOS, Integrated Services (IntServ) and Differentiated Services (DiffServ)
