Computer Networks A simple queueing system

چکیده
The letter M stands for memoryless, i.e. the Poisson process with exponential distribution. Other possibilities include D for deterministic inter-arrival times, and G denoting a general distribution of inter-arrival times. Therefore, the M/M/1 queueing system consists of customers arriving according to a Poisson process with rate λ, and one server with a service time per customer that is exponentially distributed with rate μ. This of course does not completely describe the system; for instance, what is the size of the queue where customers wait for service? We will assume an infinite queue for now as depicted below:

Product Form Queueing Networks
Queueing network models have been extensively applied to represent and analyze resource sharing systems such as communication and computer systems and they have proved to be a powerful and versatile tool for system performance evaluation and prediction. Product form queueing networks have a simple closed form expression of the stationary state distribution that allow to define efficient algorit...
متن کاملMulti-Objective Lead Time Control in Multistage Assembly Systems (TECHNICAL NOTE)
In this paper we develop a multi-objective model to optimally control the lead time of a multistage assembly system. The multistage assembly system is modeled as an open queueing network, whose service stations represent manufacturing or assembly operations. The arrival processes of the individual parts of the product, which should be assembled to each other in assembly stations, are assumed to...
متن کاملPerformance analysis of a Multiuser Multi-Packet Transmission system for WLANs in non-saturation conditions
Multiuser Multi-Packet Transmission (MPT) from an Access Point (AP) equipped with multiple antennas to multiple single-antenna nodes can be achieved by exploiting the spatial dimension of the channel. In this paper we present a queueing model to analytically study such systems from the link-layer perspective, in presence of random packet arrivals, heterogeneous channel conditions and packet err...

متن کاملImplementing the Mean Value Algorithm for the Solution of Queueing Network Models
The Mean Value Analysis (MVA) algorithm of Reiser and Lavenberg is a very simple technique for the solution of fairly complex queueing network models: This paper describes a computer program which uses the MVA algorithm to solve almost all known versions of closed queueing networks which have 'product form' solutions. Introduction Queueing network models of computer systems are emerging as both...
