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.

MAC address and controlled port based network access management

A computer-implemented method may comprise: receiving sensor data from a sensor of an autonomous vehicle; determining a presence of a lane closure object located on a lane element; determining a change of the lane closure object, selected from the presence of the lane closure object or absence of the lane closure object on the lane element; generating a change candidate based on the change in the lane closure object; obtaining a plurality of the change candidates during a time period or the autonomous vehicle being on a preceding lane element on the route; analyzing the plurality of change candidates for the change being the presence of the lane closure object or the absence of the lane closure object on the lane element; generating a final change candidate based on the change; and providing the final change candidate for updating a high definition map of the route having the lane element.
