Abstract
A process of discovering a topology of devices on a network is disclosed. A discover frame is sent to nodes in communication with a central processing unit, with the discover frame having an identification list. After a response frame from the nodes is received, the response frame is processed to determine whether a node sending the response frame has an identification value. If the node has the identification value, then a routing table is updated. When the node does not have the identification value, an identification assign frame is sent to the node and an identification assign acknowledgement frame is received from the node.
