چکیده

We consider a Lévy-driven tandem queue with an intermediate input assuming that its buffer content process obtained by a reflection mapping has the stationary distribution. For this queue, no closed form formula is known, not only for its distribution but also for the corresponding transform. In this paper we consider only light-tailed inputs, and derive exact asymptotics for the tail distribution of convex type combination of two buffer contents. This includes the marginal stationary distributions of the buffer contents and their sum as special cases. These results generalize those of Lieshout and Mandjes from the recent paper [13] for the corresponding tandem queue without an intermediate input.

Tail asymptotics for a Lévy-driven tandem queue with an intermediate input

We consider a Lévy-driven tandem queue with an intermediate input assuming that its buffer content process obtained by a reflection mapping has the stationary distribution. For this queue, no closed form formula is known, not only for its distribution but also for the corresponding transform. In this paper we consider only light-tailed inputs. For the Brownian input case, we derive exact tail a...

A tandem queue with Lévy input : a new representation of the downstream queue length

In this paper we present a new representation for the steady state distribution of the workload of the second queue in a two-node tandem network. It involves the difference of two suprema over two adjacent intervals. In case of spectrally-positive Lévy input, this enables us to derive the Laplace transform and Pollaczek-Khintchine representation of the workload of the second queue. Additionally...

Exact Tail Asymptotics of a Queue with LRD Input Traffic 59

In this work we compute the exact tail asymptotics of the stationary workload W , associated to a discretetime single server queue, with constant release rate, infinite buffer capacity, and with M/G/∞ input traffic exhibiting long-range dependence. We choose a regularly varying distribution with parameter α > 1 for the general distribution G. We show that the exact asymptotics of the workload i...

On Two-Echelon Multi-Server Queue with Balking and Limited Intermediate Buffer

In this paper we study two echelon multi-server tandom queueing systems where customers arrive according to a poisson process with two different rates. The service rates at both echelons are independent of each other. The service times of customers is assumed to be completed in two stages. The service times at each stage are exponentially distributed. At the first stage, the customers may balk ...

Transient Asymptotics of Lévy-driven Queues

With (Qt )t denoting the stationary workload process in a queue fed by a Lévy input process (Xt )t , this paper focuses on the asymptotics of rare event probabilities of the type P(Q0 > pB, QTB > qB) for given positive numbers p and q, and a positive deterministic function TB . We first identify conditions under which the probability of interest is dominated by the ‘most demanding event’, in th...
