Explicit formulas for the variance of conditioned sojourn times in M/D/1-PS
For the M/D/1 processor sharing queue, explicit formulas for the coefficient of variation of the sojourn time conditioned on the service time and on the residual service times of ...

Feedback Control with Queueing-Theoretic Prediction for Relative Delay Guarantees in Web Servers
The use of feedback control theory for performance guarantees in QoS-aware systems has gained much attention in recent years. In this paper, we investigate merging, within a singl...

Optimal Many-to-One Routing on the Mesh with Constant Queues
We present randomized and deterministic algorithms for many-to-one routing on an n-node two-dimensional mesh under the store-and-forward model of packet routing. We consider the g...

A paradox in optimal flow control of M/M/n queues
Optimal flow control problems of multiple-server (M/M/n) queueing systems are studied. Due to enhanced flexibility of the decision making, intuitively, we expect that grouping tog...

Sensitivity of Performance in the Erlang-A Queueing Model to Changes in the Model Parameters
This paper studies the M/M/s+M queue, i.e., the M/M/s queue with customer abandonment, also called the Erlang-A model, having independent and identically distributed customer aban...
