摘要: 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.

摘要: 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.

摘要: Methods for routing data units and PCI Express switches are disclosed. A plurality of devices may be coupled to a corresponding plurality of physical interfaces, each physical interface having a respective configurable status and a respective address domain, wherein in a first status the interface is transparent, and in a second status the interface is non-transparent. The status of each of the plurality of physical interfaces may be set as transparent or non-transparent. Data units may be switched between the physical interfaces using mapped address input/output, switching data units including masking the address domain for the interfaces configured as non-transparent.
