In this paper, we describe a Windows based Web cache simulator tool. This tool is able to process the IRCache based traces files and reproduce the behavior of a Web Proxy Cache. It can be configured to simulate fifteen replacement policies and two admission control policies. The cache size, the percentage of warm-up and the cost function of some replacement policies can also be configured. The ...

Next generation multi-service networks must meet basically two fundamental requirements: Quality of Service (QoS) in an Internet-based context and Traffic Engineering (TE) functionalities. DiffServ-over-MPLS stands for the most reliable solution to fulfill them in a flexible way. Anyway, even if both Diffserv and MPLS technologies have been the subjects of several works, the design and the impl...

In this paper we describe the guideline of Daphne, a parallel simulator for supervised recurrent neural networks trained by Backpropagation through time. The simulator has a modular structure, based on a parallel training kernel running on the CM-2 Connection Machine. The training kernel is written in CM Fortran in order to exploit some advantages of the slicewise execution model. The other mod...

In the context of developing next-generation high-performance computing systems, there is often a need for an “endto-end” simulation tool that can simulate the behaviour of a full application on a reasonably faithful model of the actual system. Considering the ever-increasing levels of parallelism, we take a communication-centric view of the system based on collecting application traces at the ...

The noise and complexity inherent to quantum communication networks leads technical challenges in designing network protocols using classical methods. We address this issue with a hybrid variational optimization framework (VQO) that simulates on hardware optimizes the simulation differential programming. maximize nonlocality noisy showcase our VQO framework. Using simulator we investigate robus...

OBJECTIVE The objective is to lay out the rationale for multiple resource theory and the particular 4-D multiple resource model, as well as to show how the model is useful both as a design tool and as a means of predicting multitask workload overload. BACKGROUND I describe the discoveries and developments regarding multiple resource theory that have emerged over the past 50 years that contrib...

In this article, the authors describe simulation and performance evaluation of a deployed radio communication network operated by a public safety agency. The network consists of a central site and multiple cells.Each cell has a finite number of available radio channels.The network is circuit-switched. Hence, the system utilization is a time and space distribution of the number of concurrent cal...

A network simulator is a software program that imitates the working of computer network. In simulators, the computer network is typically modeled with devices; traffic etc. and the performance are analyzed. Typically, users can then customize the simulator to fulfill their specific analysis needs. This paper gives analysis and comparison study of different wireless network simulators. Simulator...
