Method for routing data, computer program, network controller and network associated therewith

A network controller comprising a database and adapted for defining rules including at least routing rules for a respective portion of the network with which the network controller is associated, and adapted for transmitting said rules to pieces of interconnection equipment of said respective portion of the network which are adapted for routing, in the network, depending on said rules which have been transmitted to it, exchanged data between two machines,

• wherein said network controller is intended for a computer network cut out into logic network segments, including machines, each machine being identified by a machine identifier and belonging to a logic network segment within which the machines belonging to said logic network segment communicate directly with each other through the shared knowledge of their machine identifiers, a set of pieces of interconnection equipment for interconnecting the machines and a set of controllers each including a database and each associated with at least one respective portion of the network,
• wherein each controller defines, according to data stored in its database, including the set of pieces of information, rules including at least routing rules for its respective portion of the network, said routing rules being adapted so that machines belonging to a same logic network segment communicate directly with each other through the shared knowledge of their machine identifiers,
• wherein each controller transmits said rules to the pieces of interconnection equipment of said respective portion of the network,
• wherein said network controller is adapted for storing in its database, a set of pieces of information comprising an identifier of a machine matched with an associated parameter, said associated parameter including an identifier of the logic network segment to which said machine belongs and/or an identifier of an identified controller associated with a portion of the network which comprises said machine;
• and
• wherein said network controller is adapted for transmitting to another network controller said set of pieces of information with view to storage, by said other network controller, in its database of said set of pieces of information,
• wherein the identifier of the logic network segment which is stored in the database of the network controller is constituted by a unique identifier of the logic network segment.

A method for routing data in a computer network cut out into logic network segments, comprising the following steps:

• providing a computer network including machines, each machine being identified by a machine identifier and belonging to a logic network segment within which the machines belonging to said logic network segment communicate directly with each other through the shared knowledge of their machine identifiers, the computer network further including a set of pieces of interconnection equipment for interconnecting the machines, and a set of network controllers each including a database and each associated with at least one respective portion of the network;
• storing, by a network controller, in its database, of a set of pieces of information comprising the machine identifier of a machine matching an associated parameter, said associated parameter including an identifier of an identified controller associated with a portion of the network which comprises said machine;
• defining, by the network controller, rules including at least routing rules for said respective portion of the network with which the network controller is associated,
• transmitting, by the network controller, said rules to the pieces of interconnection equipment comprised in the at least one respective portion of the network with which the network controller is associated,
• routing in the network, by at least one of said pieces of interconnection equipment, exchange data between two machines according to the rules which have been transmitted to said piece of interconnection equipment,
• transmitting with the network controller to another network controller said set of pieces of information, and
• storing with said other network controller, in its database, said set of pieces of information.
