The invention relates to a method for generating, on the fly and on demand, at least one virtual network (), adapted for a specific use, on a physical network (), referred to as an infrastructure network, including physical nodes (), each of said physical nodes () runs at least one network operating system, said method including the following steps: determining, on at least one computer device (), referred to as a virtual network server, data related to said virtual network () to be generated in accordance with said particular use; transmitting, on the basis of said data and to at least a portion of said physical nodes (), referred to as active nodes, of said infrastructure network (), a request for creating a virtual node; and creating a virtual node on each of said active nodes by installing a virtual device in each of said active nodes, said virtual network consisting of all of said virtual nodes thus created. The invention also relates to a system implementing such a method.

Method and system for deploying at least one virtual network on the fly and on demand

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.

Method and computer system for triggering an action on digital communication data

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.
