Abstract: The invention relates to a method for the automated management of the performance of at least one virtual network (214, 216, 218) consisting of a plurality of virtual nodes installed on physical nodes (202, 204, 206, 208) selected from among a set of physical nodes forming an infrastructure network (200). Said method includes the following steps for each virtual network (214): determining so-called load data related to a load state of at least one virtual node (2022, 2044, 2062, 2086) of said virtual network (214); determining at least one overloaded virtual node (2086) of said virtual network (214) on the basis of said data and of at least one predefined criterion; and redefining said overloaded virtual node (214), said overloaded node benefiting from additional resources after said redefinition.

Abstract: The invention concerns a digital processing system fed by at least one filter having three possible states resulting from one or more conditions on one or more protocol attributes, specified for a semantic stream. Each protocol attribute is specified by an ordered sequence of protocol names used in the semantic stream and a parameter name carried by a protocol whereof the name is indicated in the ordered sequence of protocol names. The digital processing device comprises a filtering engine which applies the filter on the communication data until the data provide protocol attribute values wherefrom results a valid or invalid state of the filter and an action motor which triggers the action when the state of the filter is valid.

Abstract: A method for protocol identification by recognizing determinative data among data transmitted through a detected connection using lists of explicit and implicit son protocols associated with each protocol. The kernel of an information system associates to each detected connection a data structure arranged so that it comprises an ordered sequence of the protocol names. The kernel builds the data structure by retrieving the son protocol names in the list associated to the last protocol name of said ordered sequence, the son protocol name for which the associated self identification mechanism recognizes determinant data among transmitted data by adding the retrieved son protocol name to the end of the sequence and by restarting to retrieve the son protocol name for which the associated self identification mechanism recognizes determinant data among transmitted data.

Abstract: The invention concerns a method for modifying the behaviour of a network equipment (1, 4, 20) through data exchange within said equipment (1, 4, 20) between said network equipment (1, 4, 20) and a management member (11) provided in said network equipment (1, 4, 20). The invention is characterized in that said management member (11) is connected to an intelligent agent (13) included (13) in said network equipment (4, 20), said intelligent agent (13) being capable of performing reasoning, communicating and battery functions.

Abstract: The method uses a network for protocol self identification for recognizing determinative data by the naming given among data transmitted through a detected connection, and an empty or nonempty list of protocol usable namings called son protocols associated with each usable protocol naming called a father protocol. The kernel of an information system associates to each detected connection a data structure arranged so that it comprises an ordered sequence of the used protocol namings. The kernel builds the data structure by retrieving the son protocol namings in the list associated to the last naming of said ordered sequence, the son protocol naming for which the associated self identification mechanism recognizes determinant data among transmitted data by adding the retrieved son protocol naming to the end of the sequence and by restarting to retrieve the son protocol naming for which the associated self identification mechanism recognizes determinant data among transmitted data.
