    摘要: A cross-bar switch includes a set of input ports to receive data packets and a set of sink ports in communication with the input ports to receive the data packets and forward them onto a communications link. Each sink port is adapted to concurrently receive multiple data packets targeted to the same destination or multiple destinations. For example, one sink port receives a first data packet and a second data packet. The one sink port receives at least a portion of the second data packet during a time period in which the one sink port is receiving the first data packet.

    摘要: A cross-bar switch includes a set of input ports and a set of sink ports in communication with the input ports. The input ports receive packets, which are snooped by the sink ports. The cross-bar switch also includes a set of port address tables. Each port address table is adapted to store data identifying a plurality of destinations supported by a sink port. For example, a first port address table is adapted to identify a plurality of destinations supported by a first sink port in the set of sink ports. When determining whether to accept a packet, a sink port considers whether the packet's destination is identified in the sink port's port address table. By supporting multiple destinations, a port address table implicitly facilitates a sink port's multicast operation.

    摘要: A cross-bar switch includes a set of input ports for receiving data packets and a set of sink ports for transmitting the received packets to identified targets. A set of data rings couples the input ports to the sink ports. Each sink port utilizes the set of data rings to simultaneously accept multiple data packets targeted to the same destination—creating a non-blocking cross-bar switch. Sink ports are also each capable of supporting multiple targets—providing the cross-bar switch with implicit multicast capability.
