ABSTRACT:
A pseudo or virtual LAN system is formed from point-to-point communications links and dynamic configurable nodes. In each node, commands from upper layer applications are processed in Logical Link Control sub-layer station component to generate LCC data transfer requests, which are in turn converted to Data Link Control Layer data transfer requests in a LAN simulator. DLC data transfer requests are then transferred through point-to-point communication links to other one or more nodes. Asynchronously, with the above processes, a network layer manager maintains the data on the physical formation of nodes participating in the pseudo LAN system according to connection/disconnection between the node concerned and other one or more nodes.
