Abstract: A tool at the service of a distributed application running on machines of a distributed data processing system running in a local area network, intended for balancing the load on each of the machines of the system, includes a master daemon and a plurality of agent demons. The master and each of the agents calculate the load of the machine on which they are running. The master collects the load data of each of the agents at a first sampling interval and sends that collected load data to all of the agents. At the request of the distributed application, the local agent closest to the application indicates to the application which machine has the lightest load. The application then makes the decision to request the machine with the lightest load to execute the services the application requires. As necessary, the tool selects a master from the agents, thereby ensuring the existence and uniqueness of a master at all times, regardless of failure affecting one 1010 or more machines in the data processing system.

Abstract: An open computing system including a central client system and a plurality of server systems connected through a network, wherein the servers each include load calculators for calculating the load on the server at predetermined first sampling instants, a load rate calculator for determining the progress rate of the load on each server and memory for storing the load and the progress rage. The client includes means for polling, which at predetermined second sampling instants, requests each server to furnish the progress rate of the load and an average load over a predetermined number of first sampling instances, memory for storing the progress rate of the load and the average load, and a server selector for selecting the least loaded server to provide services for an application running on the client. The system optimizes the selection of servers in a multi-server system.

Abstract: A process for protecting software written for a computer (ORD) in interpreted language, in which the program is written in uncoded form in a script file (FSI), and a compiled code (EXECI) is generated from the content of this file (FSI). This compiled code (EXECI) is then executed, which creates a pipeline (PI) for communicating with an interpreter (INTI) associated with the language used in this file (FSI). The interpreter is supplied through this pipeline (PI), with the content of the initial script file. The interpreter reads the content and executes it in the computer (ORD).

Abstract: The invention relates to a process for simulating, in a network, a server architecture from a client architecture in a first machine (PS) for the execution of remote procedure calls (RPC sent by at least one machine with client architecture (CL). In this this process, the first machine (PS) initially sends an RPC call to a third machine with server architecture (RE) which is used as a relay machine between the first (PS) and the second (CL) machines, and this RPC call opens a communication context for the sequence of exchanges while the first machine (PS) blocks itself on standby for a return of the RPC call. When the second machine (CL) sends an RPC call which represents a predetermined function to be executed by the first machine (PS), this call is transmitted to the relay machine (RE) which, after recognizing the function, retransmits it to the first machine (PS) through a return of the blocked RPC call.

Abstract: A process for monitoring the acknowledgement of a request to execute a command script (script) through a non-guaranteed protocol (S.N.M.P.), in an information system (SI) in a network (RE) comprising a manager (GE) and agents (AG1) for executing commands, wherein the manager first sends the agent in charge of executing the command script a ticket request using a command (Get mrsGetTK) of the "get" type, and the agent returns (GetResponse) a ticket to the manager, the manager then sends the execution request to the agent using a command (Set mrsExecute cmd TK) of the "set" type, for which the ticket it a parameter, then the agent verifies the validity of the request and creates an instance for the execution of the command associated with the ticket and the manager then verifies proper reception of the request by scanning (Get mrsStatus) the instance using the agent. The instant invention is particularly applicable to heterogeneous information systems.

Abstract: The invention relates to an address conversion process for porting a telecommunications application APP from the TCP/IP network to the OSI/CO network, and to an address conversion module used in this process. In a known manner, access to the networks is authorized by way of a "socket" interface (SOC) for the TCP/IP network, and an "XTI" interface for the OSI/CO network. In a notable manner, the "socket" interface calls (SC), like a plurality of system cells (SY), are in a first time period oriented, at the moment of the link editing phase prior to obtaining the executable, to a module (W) for automatic address conversion of the library type. This module (W) then performs the conversion of the addresses specific to the TCP/IP network into addresses of the OSI/CO network and enables the passage from the TCP/IP protocol to the OSI/CO protocol. After conversion, the calls are transmitted to the "XTI" interface and can be used directly in the OSI/CO network.
