METHOD FOR DYNAMIC CONTROL OF ADDRESSES FOR ACCESS CONTROL TO AN ETHERNET NETWORK

摘要

The invention relates to a dynamic control method for at least one access control address for at least one terminal (10) to a broadcast network (R2) of the bus type via a frame switching unit (20), said terminal having at least one physical address for access control associated with a line between the terminal (10) and said unit (20). According to the invention, the method comprises the following steps: at the terminal (10), transmission to the unit (20) of a request for assignment of a virtual access control address, said request comprising at least one physical access control address for the terminal (10), at the unit (20), transmission to the terminal (10) of a reply to said request, containing a virtual access control address allocated to the terminal, said virtual access control address being chosen from a list of virtual access control addresses available on said line and registering the allocation of said virtual access control address to the physical access control address of the line in a reference table. Of application to access security to an Ethernet network.
