ABSTRACT:
Multiple different operational capabilities, such as data transfer rates or communication protocols, are selectable for use on a single LAN. Enchanced nodes of the LAN have the capability of utilizing either an enhanced capability or a common capability in communicating with other nodes. Those basic nodes which are not of the enhanced variety have the capability of communicating utilizing the common capability. The enhanced nodes dynamically select the operational capability for the most efficient communication with other nodes.
