Assignee:

3COM Corporation - Santa Clara CA

International Classification:

G06F 900
G06F 1500

US Classification:

395500

Abstract:

A local net area network, or LAN, configuration is provided with a multiple generic LAN channel architecture which can be logically and dynamically changed. The configuration control can be applied to each module of the network and to each port of a module of a LAN hub. The architecture provides multiple LAN protocols to be used simultaneously, as needed, through protocol specific functions. Industry standard protocol such as: token bus, token ring, and fiber distributed data interface (FDDI), can be implemented using the generic channel architecture and its characteristics providing respective network functions. The architecture also provides a digital collision detection method and provides information necessary for precise network statistics monitoring. The token passing ring architecture provides a logical ring formation within the generic channel. A token passing bus architecture uses modified Ethernet. TM.
