Analysis of a Queueing Model with Delayed Feedback and its Application to the ABR Flow Control

چکیده
A common method for regulating the input ow in today s telecommunication networks is the implementation of reactive tra c control mechanisms By limiting the user s ac cess according to the current network load situation the throughput is optimized while congestion is avoided In ATM networks for example a rate based feedback control is applied to dynamically adjust the transmission rates of connections belonging to the ABR service category This paper presents a discrete time analysis of a queueing model with non deterministic arrivals and delayed feedback The binary feedback information is used to regulate the input ow by changing the inter arrival distribution accordingly Applying this model the performance of the ABR ow control can be studied with respect to the variability of the cell generation process

N-Policy for M/G/1 Machine Repair Model with Mixed Standby Components, Degraded Failure and Bernoulli Feedback
In this paper, we study N-policy for a finite population Bernoulli feedback queueing model for machine repair problem with degraded failure. The running times of the machines between breakdowns have an exponential distribution. The repair times of the machines are independent and identically distributed random variables. If at any time a machine fails, it is sent to the repairman for repairing,...
متن کاملAnalysis and Dimensioning of Credit-based Flow Control for the Abr Service in Atm Networks
ATM networks have shown to reveal difficulties in simultaneously guaranteeing the requested Quality-of-Service while efficiently utilizing all the available bandwidth for economic reasons. The ABR (available bit rate) service class was designed to fill the gap of bandwidth with less delay but loss sensitive traffic. Due to the bursty nature of higher-priority traffic and the resulting bandwidth...
متن کاملCapacity planning in the hospital queueing network with blocking: simulation-based optimization approach
Introduction: Hospital administrators have always faced the challenge of providing the best possible health services in a resource-limited environment. The patient flow throughout the hospital is affected by lack of the capacities that can lead to bed-blocking among the hospital units. In this research, the patient flow in the hospital is modeled as an open queueing network with blocking. Then,...
متن کاملPerformance Analysis of Rate Based Feedback Control for ATM Networks
Closed-loop input rate regulation schemes have come to play an important role in the transport of the Available Bit Rate (ABR) traac service category for ATM. In this paper, we present a numerical approach to the performance study of a delayed feedback system with one congested node and multiple connections. This approach consists in modeling the feedback system as a nite Quasi-Birth-Death (QBD...
متن کاملDiscrete Time Analysis of Multi-Server Queueing System with Multiple Working Vacations and Reneging of Customers
This paper analyzes a discrete-time $Geo/Geo/c$ queueing system with multiple working vacations and reneging in which customers arrive according to a geometric process. As soon as the system gets empty, the servers go to a working vacations all together. The service times during regular busy period, working vacation period and vacation times are assumed to be geometrically distributed. Customer...
