Database systems recover persistent data, providing high database availability. However, database applications, typically residing on client or “middle-tier” application-server machines, may lose work because of a server failure. This prevents the masking of server failures from the human user and substantially degrades application availability. This paper aims to enable high application availa...

This paper is on the construction of a server subsystem in a client/server system in an application context where the number of potential clients can be arbitrarily large. The implementation of the server is based on the well-known Triple Modular Redundancy (TMR) technique. The three server processes must process the client inputs in the same order to keep the server state consistent. While a c...

A distributed le system provides le service from one or more shared le servers to a community of client workstations over a network. While the client-server paradigm has many advantages, it also presents new challenges to system designers concerning performance and reliability. As both client workstations and le servers become increasingly well-resourced, a number of system design decisions nee...

To keep up with demand, servers will scale to handle hundreds of thousands clients simultaneously. Much the focus community has been on scaling in terms aggregate traffic intensity (packets transmitted per second). However, bottlenecks caused by increasing number concurrent clients, resulting a large flows, have received little attention. In this work, we identifying such bottlenecks. particula...

The possibility of sharing information through networking has been growing in geometrical progression. In this connection it is to be noted network attacks, in other words, DDoS attacks also are growing in equal proportion. Sharing of information is being carried out by means of server and client. The client requests for the data from the server and the server provides the response for the clie...

This paper describes the design of a client/server architecture for machine vision. The server is constructed as a virtual machine, permitting client software to be platform-independent. The client architecture consists of a number of proxy classes that hide the details of server communication, simplifying the construction of client applications. Serializable objects are used for communication ...

The paper studies a closed queueing network containing a server station and k identical client stations. The client stations are subject to breakdowns, and a lifetime of each client station is assumed to be a random variable independent of all other ones having the probability distribution ) (x G . The server station is an infinite server queueing system, and client stations are single server q...

In recent years, Video Streaming has undoubtedly taken up major chunk of bandwidths in Internet. This can be attributed to several streaming sites that have become very popular [1, 2]. But, in today's high demand for multimedia streaming, the high bandwidths provided from the server can become scarce quickly, making the server link a bottle neck. The more popular the server becomes, many more r...
