Router Congestion Control [PDF]

open access: yes, 2004
Congestion is a natural phenomenon in any network queuing system, and is unavoidable if the queuing system is operated at capacity. In this thesis, we study how to set the rules of a queuing system so that all the users have a self interest in ...

Specific cost ratio in a port modelling by M/Ek/1 queue [PDF]

open access: yesFME Transactions, 2018
The notion of specific cost ratio involves different type of costs of a ship and a port modeled as a queueing system. Using the known general formula for the specific cost ratio of arbitrary port queueing system (denoted as R), here we derive the related

A Discrete-Time Geo/G/1 Retrial Queue with J Vacations and Two Types of Breakdowns

open access: yesJournal of Applied Mathematics, 2013
This paper is concerned with a discrete-time Geo/G/1 retrial queueing model with J vacations and two types of breakdowns. If the orbit is empty, the server takes at most J vacations repeatedly until at least one customer appears in the orbit upon ...

THE RAILWAY INFORMATION SYSTEM AS A QUEUEING SYSTEM [PDF]

open access: yesTRANSPORT, 2009
The present article dwells upon the Information System (IS) of Latvian railways providing the analysis of the queuing system (QS) used to removing defects occurring in the infinite linear queuing system. The author of the article analyzes research data about the failures of system functioning in order to establish the parameters of the before mentioned
