There is disclosed apparatus and methods of multicasting in a shared address space. A shared memory address space may include two or more multicast portions. Each multicast portion may be associated with a respective end point and with at least one other multicast portion. Data units may be transmitted to at least some of the end points via memory-mapped I/O into the shared memory address space. When a destination address of a data unit is in a first multicast portion associated with a first end point, the data unit may be transmitted to the first end point, revised to specify a destination address in a second multicast portion associated with the first multicast portion, and transmitted to a second end point associated with the second multicast portion.

Multicasting computer bus switch

There is disclosed a bus optimization technique. Pursuant to the bus optimization technique, the output buffer and output logic are removed from port units of a switch and are included with a control matrix in the switch. Data units received in a first port unit of a plurality of port units are provided to a control matrix. The control matrix evaluates when to send the data unit to a second port unit. No output decisions are made in the second port unit.

Optimized switching method

There is disclosed apparatus and methods of multicasting in a shared address space. There may be defined a number of portions of the address space. There may be groups of the portions, and data units addressed to one portion within the group may be re-addressed to the other portions.
