Abstract
Network switches and methods are disclosed. A network switch may include multiple input ports and multiple output ports, a switch fabric, and switch controller. The controller may receive and store data identifying a plurality of users and data defining which input ports and which output ports each user has authority over. The controller may receive, from a requesting user from the plurality of users, a request to make a connection between a selected input port and a selected output port. The controller may determine, based on the stored data, if the requesting user has authority over both the selected input port and the selected output port. The controller may refuse to make the requested connection if the requesting user does not have authority over both the selected input port and the selected output port.
