The MARIAN system, like many information systems, can be divided in to a client part and a server part (Fig. 1). Historically, MARIAN was designed to support stand-alone single-user clients running on desktop machines. Although some of these clients are still in existence, this has not been the primary means of interacting with the system since the Web revolution of the mid-1990s. Most users no...

This paper describes the design and implementation of Paradise, a database system designed for handling GIS type of applications. The current version of Paradise, uses a client-server architecture and provides an extended-relational data model for modeling GIS applications. Paradise supports~an extended version of SQL and provides a graphical user interface for querying and browsing the databas...

An important aspect of the design of distributed systems is the degree to which it is possible to change their configuration as requirements vary. This paper addresses the issues of reconfiguring server software in a distributed system at run-time. In particular, it is concerned with externally imposed reconfigurations, which avoid explicit interactions with the servers being reconfigured or th...

Client–server computing is a distributed computing model in which client applications request services from server processes. Clients and servers typically run on different computers interconnected by a computer network. Any use of the Internet (q.v.), such as information retrieval (q.v.) from theWorldWideWeb (q.v.), is an example of client–server computing. However, the term is generally appli...

This short paper discusses two issues of hypermedia link management over distributed information collections. The hypermedia system is a client requesting data and computation services from servers, which are autonomous applications such as storage applications and computational applications. The first issue is the distinction between an intranet and the Internet as environments supporting the ...

The Network Configuration Protocol (NETCONF) defines ways to read and edit configuration data from a NETCONF server. In some cases, part of this data may not be set by the NETCONF client, but rather a default value known to the server is used instead. In many situations the NETCONF client has a priori knowledge about default data, so the NETCONF server does not need to save it in a NETCONF conf...

This thesis examines the provision of on-demand multimedia streaming services using clusters of commodity PCs. In the proposed HammerHead multimedia server cluster architecture, a dynamic content replication policy is used to assign non-disjoint subsets of the presentations in a multimedia archive to cluster nodes. Replicas of selected presentations can be created on more than one node to achie...

In this model we propose Algorithm to optimize the performance of the distributed systems over the internet. Their consist of large number of clients and servers. The servers consist of large number of clients for this the load is increases on the server to process the data. Here the goal of our proposed system is to assign the clients to the servers and reduce the load on server and minimize t...
