Abstract
A set of software components has been created to form a path of execution outside of a kernel that triggers the authentication process based on MAC address determination for connected stations and separately managing that authentication per controlled port shared across stations. The architecture of the set of software components includes a control daemon that interacts with objects and services of the network access point OS or kernel to leverage dynamic host configuration protocol (DHCP) snooping and MAC address learning to determine MAC addresses. The control daemon instantiates an authenticator object/service for each controlled port and interacts with the authenticator object/service to cause an authenticator service of the OS to perform the authentication process for stations. The control daemon also leverages an Ethernet frames rules table of the kernel to authorize traffic of authenticated stations via the controlled port.
