This paper presents a mechanism that facilitates and enhances the use of independently administered remote network servers in the presence of server interface heterogeneity. The mechanism is designed under the client-service model, which extends the client-server model with an abstraction of service to decouple abstract server capabilities from concrete server interface specifics such as server...

In this study, we consider the relationship of client IO requests submitted to a file server and the server's disk subsystem IO traffic. We collected traces of client-server IOs and, during each trace period, we also traced server storage subsystem workloads. We analyze and compare trace pairs collected in each trace period. We evaluate file server performance and investigate the relationship b...

Applications that use directory services or relational databases operate in a client–server model, where a client requests information from a server, and the server returns a response to the client. These client–server applications typically have a specific message protocol that is unique to that application. Systems with multiple client–server applications require that there are separate clien...

Gold Rush is middleware supporting the writing of Java applications that reside on an intermittently connected mobile client device and access an enterprise database on a central server. While the client is connected to the central server, objects constructed from database entities can be cached in a persistent store on the client. While the client is disconnected, these entities can be manipul...

In recent years, mobile devices have gained increasing development with stronger computation capability and larger storage space. Some of the computation-intensive machine learning tasks can now be run on devices. To exploit resources available preserve personal privacy, concept client-based has been proposed. It leverages users' local hardware data to solve sub-problems only uploads results ra...

While early web applications were created with all data processing done on the server, the expansion in the use of scripting languages embedded in web browsers (specifically, dialects of ECMAscript JavaScript and JScript) in techniques such as AJAX have allowed for change in the design of web applications. They are no longer run solely on the server-side with a limited input interface of static...

Widespread replication of information can ameliorate the problem of server overloading but raises the allied question of server selection. Clients may be assigned to a replica in a static manner or they may choose among replicas based on client-initiated measurements. The latter technique, called dynamic server selection (DSS), can provide signi®cantly improved response time to users when compa...
