- ABSTRACT: In this paper we propose a new paradigm for a Differential
Service (DiffServ) network consisting of two-color marking at the edges
of the network using token buckets coupled with differential treatment
in the core. Using fluid-flow modelling, we present existence conditions
for token-bucket rates and differential marking probabilities at the
core that result in all edges receiving at least their minimum guaranteed
rates. We then present an integrated DiffServ architecture comprising
of an active rate management controller at the marking edge and a two-level
active queue management controller at the core. The validity of the
fluid
flow model and performance of this new scheme are verified using \texttt{ns}
simulations.
