摘要： The distributed switch may include a plurality of chips (i.e., sub-switches) on a switch module. These sub-switches may receive from a computing device connected to a Tx/Rx port a multicast data frame (e.g., an Ethernet frame) that designates a plurality of different destinations. Instead of simply using one egress connection interface to forward the copies of the data frame to each of the destinations sequentially, the sub-switch may use a plurality of a connection interfaces to transfer copies of the multicast data frame simultaneously. The port that receives the multicast data frame can borrow the connection interfaces (and associated hardware such as buffers) assigned to these other ports to transmit copies of the multicast data frame simultaneously.

摘要： A method is provided for processing a command issued by a processor over a bus. The method includes (1) transmitting the command to a remote node to obtain access to data required to complete the command; (2) receiving from the remote node a response packet including a header and a header CRC; (3) validating the response packet including the header and the header CRC; (4) loading a timer to run until data required to complete the command is received or the timer expires; and (5) before receiving the data required to complete the command, arranging to return the data to the processor over the bus.

The method includes the steps of (1) transmitting the command to a remote node to obtain access to data required to complete the command; (2) receiving from the remote node a response packet including a header and a header CRC; (3) validating the response packet based on the header CRC; and (4) before receiving the data required to complete the command, arranging to return the data to the processor over the bus.

摘要： A method is provided for processing a command issued by a processor over a bus. The method includes (1) transmitting the command to a remote node to obtain access to data required to complete the command; (2) receiving from the remote node a response packet including a header and a variable gap; and (3) before receiving the data required to complete the command, arranging to return the data to the processor over the bus.
