Keywords:

  • tools, classifiers - concept of Per-Hop Behavior (PHB) - each router in network implementing its own QOS settings;
  • classifier tool, assigning a class of service to each packet;
  • classification, operation implemented using - set of IF/THEN rules, in the form of “IF (match conditions), THEN (class of service assignment)”;
  • three specific realms, Ethernet, IP and MPLS - realm relating to level at which packet is processed by classifier;
  • packets' QOS markings – straightforward, and most popular ones;
  • classifier inspecting packet - targeting known location of QOS marking;
  • packet classification process, straightforward - classifier knowing, which packet to look for QOS markings;
  • classification and packets' QOS markings – popular, deployed classification process;
  • MPLS-TE capabilities of establishing LSPs - bandwidth reservations, end to end;
  • mixing different QOS realms - mix of technologies, between traffic flow end points
