20080307146 | STRUCTURE FOR DYNAMICALLY SCALABLE QUEUES FOR PERFORMANCE DRIVEN PCI EXPRESS MEMORY TRAFFIC - A method, computer system, and PCI Express device/protocol for a design structure that enables high performance IO data transfers for multiple, different IO configurations, which include variable packet sizes and/or variable/different numbers of transactions on the IO link. PCI Express protocol is enhanced to support utilization of counters and dynamically variable queue sizes. In addition to the standard queue entries, several (or a selected number of) dynamically changeable queue entries are provided/reserved and a dynamic queue modification (DQM) utility is provided within the enhanced PCI Express protocol to monitor ongoing, current data transfer and manage when the size(s) of the queue entries are modified (increased or decreased) based on current data traffic transmitting on the PCI Express IO link. The enhanced PCI Express protocol provides an equilibrium point at which many large data packets are transferred efficiently, while imposing a limit on the number of each size of packets outstanding. | 12-11-2008 |

20130242985 | MULTICAST BANDWIDTH MULTIPLICATION FOR A UNIFIED DISTRIBUTED SWITCH - 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. | 09-19-2013 |
