Defining Quality of Service

• A service is needed to relate quality:

  • Service: Food delivery
    • rate of delivery (Burger King)
    • quality of food delivered (Fancy restaurant)
    • Quantity (buffet)
  • IP Service: Packet delivery
    • rate of delivery (file transfer)
    • latency + jitter of delivery (interactive apps: http, telnet, multimedia)

• A caste system?

  • Some Animals have more rights
    • The bit haves and the have-nots defined by $$?
