چکیده

Tremendous amounts of effort have gone into research on switch designs and architectures. This survey attempts to sketch the evolution of the modern switch architectures. The survey covers the literature over the period 1987-2008 on switch architectures. Starting with the simple crossbar switch, we explore various architectures such as Output queueing, Input queueing, Combined Input/Output queueing, buffered crosspoint etc., that have evolved during this period. We discuss the pros and cons of these designs, so as to shed light on the path of evolution of switch architecture.

PERFORMANCE OF DIFFERENT ANT-BASED ALGORITHMS FOR OPTIMIZATION OF MIXED VARIABLE DOMAIN IN CIVIL ENGINEERING DESIGNS

Ant colony optimization algorithms (ACOs) have been basically introduced to discrete variable problems and applied to different research domains in several engineering fields. Meanwhile, abundant studies have been already involved to adapt different ant models to continuous search spaces. Assessments indicate competitive performance of ACOs on discrete or continuous domains. Therefore, as poten...

A Survey of Concurrency Control Algorithms in the Operating Systems

Concurrency control is one of the important problems in operation systems. Various studies have been reported to present different algorithms to address this problem, although a few attempts have been made to represent an overall view of the characteristics of these algorithms and comparison of their capabilities to each other. This paper presents a survey of the current methods for controlling...

A Comparative Study of Four Evolutionary Algorithms for Economic and Economic-Statistical Designs of MEWMA Control Charts

The multivariate exponentially weighted moving average (MEWMA) control chart is one of the best statistical control chart that are usually used to detect simultaneous small deviations on the mean of more than one cross-correlated quality characteristics. The economic design of MEWMA control charts involves solving a combinatorial optimization model that is composed of a nonlinear cost function ...

طراحی سوئیچ تمام نوری با استفاده از خاصیت غیر خطی Kerr وDIT با نانو کریستال چهار ترازه

We propose a novel two state and all-optical controllable switch using DIT, Kerr effect and interaction between quantum dots (QD) and quantum electrodynamics cavity (CQED). The two state and all-optical controllable switch is coupled to photonic waveguide from a rapid nonlinear environment (photonic crystal) and CQED. We consider the nano-crystal are doped to crystal photonic cavity as a 4-leve...
