A method of broadcasting an information packet in a network including a sender of the packet and a plurality of recipients connected by a network equipment of a routing server, the routing server including a physical computing system and a software system, and the physical computing system operating alternatively between a kernel mode and a user mode. The software system controls the implementation of a step of receiving the packet, and, for each recipient, a step of duplicating the packet. The software system also controls the implementation of a step of routing the packet thanks to an IP address of the recipient, and a step of sending the packet to the recipient, wherein each step is executed by the physical computing system in kernel mode.
