An important property of a client/server system is the independence of the interaction between the server and a client from the interactions that the server might have with other possible clients. In this paper we try to give a deenition of such a property, that we called linearity, by means of the Process Algebra formalism. Through some examples of linear and non linear systems, we illustrate ...

In this paper we present a new Document Management System called DrStorage. This DMS is multi-platform, JCR-170 compliant, supports WebDav, versioning, user authentication and authorization and the most widespread file formats (Adobe PDF, Microsoft Office, HTML,...). It is also easy to customize in order to enhance its search capabilities and to support automatic metadata assignment. DrStorage ...

A distributed file systetn provides file service from one or rnore &red file servers to a community of clierit workstations o’ver Q network. Wlaile the clientserver paradigm has many advantages, it also presents new challenges to system designers concerning perforrnance and reliability. As both client workstations and file servers become increasingly well-resourced, a nu~nber of system design d...

In traditional client-server designs, all requests are processed at the server storing the state, thereby maintaining strict locality between computation and state. The adoption of RDMA (Remote Direct Memory Access) makes it practical to relax locality by letting clients fetch server state and process requests themselves. Such client-side processing improves performance when the server CPU, ins...

An overview of the basic principles and approaches for extracting information processing from web pages has been conducted. A methodology developing a client-server system based on tool automation work in Selenium browsers analyzed about data parsing created. third-party API as user interface to simplify speed up development used. User access without downloading additional software enabled. Dat...

In this paper, we propose an efficient client-to-client streaming approach to cooperatively stream the video using chaining technique with unicast communication among the clients. This approach considers two major issues of VoD 1) Prefix caching scheme to accommodate more number of videos closer to client, so that the request-service delay for the user can be minimized. 2) Cooperative proxy and...
