A scalable Ethernet switch includes modules which can be interconnected to provide a single, virtual switch. The modules may be of uniform physical size and shape relative to a standard telecommunications rack. When greater capacity is required, an additional module is mounted in a rack and interconnected with the other modules, e.g., in a bi-directional ring. Enhanced port density is provided by interconnecting the modules with 12 GbE links which operate on standard 10 GbE wiring and connectors. Consequently, throughput between modules in increased relative to standard 10 GbE links without increasing form factor. Further, transmission power control can be implemented such that modules of the virtual switch may be physically adjacent or separated by distances of several meters. |
