| With this work, we present a scalable
relative differentiated services architecture based on bandwidth
shares: Scalable Bandwidth Share Differentiation (SBSD). SBSD has
been designed to provide isolation and differentiation of user
traffic without per-flow or per-user state at the core nodes. In
addition, SBSD preserves this isolation and differentiation when
being scaled over domain boundaries. The presented SBSD
architecture leads to a weighted maxmin fair bandwidth
distribution with respect to each user\'s sending rate. The
novelty of the resulting fairness distribution is that ist is
user-based, in contrast to traditional fairness criteria dealing
with flows. Even though SBSD operates at a per-user granularity,
it allows more fine-grained differentiation, which we use to
demonstrate how multicast can be integrated in a straight-forward
manner and how SBSD can be optimized for end-to-end TCP
congestion control. |
