Abstract
| We consider a switching system which has multiple
ports that share a common buffer, in which there is a
FIFO logical queue for each port. Each port may support
a large number of flows or connections, which are approximately
homogeneous in their statistical characteristics, with
common QoS requirements in cell loss and maximum delay.
Heterogeneity may exist across ports. Our first contribution
is a buffer management scheme based on Buffer Admission
Control, which is integrated with Connection Admission
Control at the switch, and is at the same time fair,
efficient and robust in sharing the buffer resources across
ports. Our scheme is based on the resource-sharing technique
of Virtual Partitioning. Our second major contribution
is to advance the practice of discrete-event fluid simulations.
Such simulations are approximations to cell-level
simulations and offer orders of magnitude speed-up. A third
contribution of the paper is the formulation and solution of
a problem of optimal allocati...
