  • TITLE: Throughput Differentiation Using Coloring at the Network Edge and
    Preferential Marking at the Core
  • AUTHOR: Y. Chait, C.V. Hollot, V. Misra, D. Towsley, H. Zhang and Y. Cui
  • ABSTRACT: In this paper we introduce an innovation in differentiated services architecture consisting of adaptive two-level coloring at the edge and preferential marking at the core. We identify general properties of these two processes which, when met, guarantee a desirable fixed point for the network; i.e., one where aggregated flow rates meet or exceed given targets in an over-provisioned network. Specific mechanisms realizing the aforementioned properties lead to so-called active rate management controllers for edge coloring, and a preferentially-marking, active queue management controller at the core. We discuss stability of the fixed point for this network, and validate results using \texttt{ns} simulations.
