Internet or WEB computing concepts, such as the Web Operating System (WOS™), require suitable methods for finding the most effective hardware and software environment for an application execution on the network. We present an efficient search strategy and show that the resulting communication load penalty is well acceptable while preventing the network from being flooded by administrative...

Self-similar or multifractal behavior has been observed for LAN and Internet WAN (backbone) traffic. Investigations about this kind of behavior for application level protocols are rarely found because sessions or even applications are usually too short to be characterized in this direction. Only Telnet and FTP were examined so far. This paper analyzes the traffic shape of Peer-to-Peer (P2P)...

CORBA has been designed while supposing that the network capacity is always sufficiently large. This however, is not always the case. In particular, we note the case of Command and Control Systems (C2S) using CORBA for communication between distributed subsystems. These C2S need to guarantee the transmission of data, even in extreme situations where the com- munication performance may drop to as...

Market design is becoming a very important research topic in the context of the electronic economy. Two factors explain this trend: (1) the creation of new markets to facilitate deregulation (telecommunication frequencies, electric power, etc.) and (2) the emergence of strategic analysis and of experimental economics. E-commerce tools will contribute to the emergence of more structured...

The complex structure of the Web requires decentralised, adaptive mechanisms efficiently providing access to local and global capacities. To facilitate the development of such mechanisms, it seems to be reasonable to build clusters or grids of machines with similar structures and interests. In such a manner, communities of machines can be built. In a community, every machine contributes to the...

Current tools available for high performance computing require that all the computing nodes used in a parallel execution be known in advance: the execution environment must know where the different "chunks" of programs will be executed, and each computer involved in the execution must be properly configured. In this paper, we describe how the Web Operating System (WOS™) environment may be used...

This paper presents work related to the design of distributed systems, which is useful for emerging Internet applications. We propose algorithms for searching and managing distributed information about resources and services using locally available warehouses. The concept of warehouses has been introduced in the Web Operating System (WOS) (Kropf 1999). Warehouses have the ability to decide which...

The World-Wide Web consists not only of informational, but also computational resources. However, these resources, especially computational ones are underutilized. One characteristic of theWeb is its ever changing structure; for instance, nodes are dynamically added and removed. This makes it difficult, if not impossible, to draw a complete and accurate picture of available resources. We consider...

Given the current development of the Internet, the Web, mobile communications and services, we are clearly head- ing towards an era of widely integrated ubiquitous services sharing some kind of global operating system. This arti- cle describes the idea, the objectives and the current state of the development of the WOS-project. The Web Operat- ing System (WOS") consists of a series of versioned...

Most of the development environments for high performance parallel applications require that all the computing modules and resources be known in advance. The execution environment must know where the different program modules will be executed, and must properly configure each computer involved in the execution. We describe how the Web Operating System (WOSTM) environment may be used to...
