Waiting times of the Multiple Priority Dual Queue with Finite Buffer and Non- Preemptive Priority Scheduling

This paper considers a novel queueing model called the Multi-Priority Dual Queue (MPDQ), which was introduced and analyzed in Bedford and Zeephongsekul [1, 2]. The MPDQ consists of two queues with a finite buffer, the primary and the secondary queue with the additional feature of a priority scheme to assist with congestion control and meeting Quality of Service ( ) QoS objectives for differenti...

Waiting times in classical priority queues via elementary lattice path counting

In this paper, we describe an elementary combinatorial approach for deriving the waiting and response time distributions in a few classical priority queueing models. Bymaking use of lattice paths that are linked in a natural way to the stochastic processes analyzed, the proposed method offers new insights and complements the results previously obtained by inverting the associated Laplace transf...

Tail probabilities of low-priority waiting times and queue lengths in MAP/GI/1 queues

We consider the problem of estimating tail probabilities of waiting times in statistical multiplexing systems with two classes of sources { one with high priority and the other with low priority. The priority discipline is assumed to be nonpreemptive. Exact expressions for the transforms of these quantities are derived assuming that packet or cell streams are generated by Markovian Arrival Proc...

Waiting for a Retweet: Modeling Waiting Times in Information Propagation

Social media are increasingly used to disseminate emergency warnings, alerts, and other hazard-related information. In this context, the timing of information propagation is of immediate interest. Time-sensitive information must reach members of the general public before the pertinence of the information expires. In this research we build a preliminary model for the time between information dis...
