Streaming high quality videos consumes significantly large amount of network resources. In this context request-toservice delay, network traffic, congestion and server overloading are the main parameters to be considered in video streaming over the internet that effect the quality of service (QoS). In this paper, we propose an efficient architecture as a cluster of proxy servers and clients tha...

Due to the limited cache size in each server, the traditional neural network techniques applied to improve the cache hit rate of scheduling algorithm in load-balancing web server cannot provide a good performance real web site because it cannot balance the server workload properly. Here, we propose a fuzzy neural network technique by feeding back the real-time system usage with an updating mapp...

Status of this Memo This memo provides information for the Internet community. It does not specify an Internet standard of any kind. Distribution of this memo is unlimited. 1. Abstract This document describes how proxy chaining and policy implementation can be supported in roaming systems. The mechanisms described in this document are in current use. However, as noted in the security considerat...

PATHWORKS network operating system software runs on the remote server computer that accesses files on behalf of clients connected to a network. The PATHWORKS file server provides clients with centralized backup, printing, and security. Popular desktop applications can be used in a manner that consumes large or small amounts of server resources. Capacity planning seeks to determine which network...

Abstract— Bot networks are a serious threat to cyber security, whose destructive behavior affects network performance directly. Detecting of infected HTTP communications is a big challenge because infected HTTP connections are clearly merged with other types of HTTP traffic. Cybercriminals prefer to use the web as a communication environment to launch application layer attacks and secretly enga...

Server network performance is increasingly dominated by poorly scaling operations such as I/O bus crossings, cache misses and interrupts. Their overhead prevents performance from scaling even with increased CPU, link or I/O bus bandwidths. These operations can be reduced by redesigning the host/adapter interface to exploit additional processing on the adapter. Of oading processing to the adapte...

MADNet is a user-friendly data mining and visualization tool for rapid analysis of diverse high-throughput biological data such as microarray, phage display or even metagenome experiments. It presents biological information in the context of metabolic and signalling pathways, transcription factors and drug targets through minimal user input, consisting only of the file with the experimental dat...

This paper focus on the deployment of grid infrastructures, more specifically Problem Solving Environments (PSE) for numerical applications on the grid. Even if the deployment of such an architecture is forced by physical constraints (firewall, access permission, security,. . . ) its efficiency heavily depends on the quality of the mapping between its different components and the grid resources...

Network calculus is a deterministic queuing theory that has gained increasing attention in recent time. Founded on min-plus algebra it resorts to intuitive convolution formulae for efficient concatenation of servers and derivation of related performance bounds. Yet, the pessimistic worst-case analysis of deterministic network calculus gave rise to probabilistic counterparts that aim at utilizin...

In this paper, the authors have focused on the stochastic analysis of an internet data center (IDC), which consists of a database main server connected to a redundant server. Observing the different possibilities of functioning of the system, analysis has been done to evaluate the various reliability characteristics of the system. The system can completely fail due to failure of redundant serve...
