          Differentiated Services (short: Diffserv) is an architecture for
          providing different types or levels of service for network traffic.
          One key characteristic of Diffserv is that flows are aggregated in
          the network, so that core routers only need to distinguish a
          comparably small number of aggregated flows, even if those flows
          contain thousands or millions of individual flows.
