| 20080320181 | Hardware-Based Virtualization of BIOS, Disks, Network-Interfaces, & Consoles Using a Direct Interconnect Fabric - A multi-computer system has many processors that share peripherals. The peripherals are virtualized by hardware without software drivers. Remote peripherals appear to the operating system to be located on the local processor's own peripheral bus. A processor, DRAM, and north bridge connect to a south bridge interconnect fabric chip that has a virtual Ethernet controller and a virtual generic peripheral that act as virtual endpoints for the local processor's peripheral bus. Requests received by the virtual endpoints are encapsulated in interconnect packets and sent over an interconnect fabric to a device manager that accesses remote peripherals on a shared remote peripheral bus so that data can be returned. Ethernet Network Interface Cards (NIC), hard disks, consoles, and BIOS are remote peripherals that can be virtualized. Processors can boot entirely from the remote BIOS without additional drivers or a local BIOS. Peripheral costs are reduced by sharing remote peripherals. | 12-25-2008 |

| 20090216920 | Dis-Aggregated and Distributed Data-Center Architecture Using a Direct Interconnect Fabric - A data center has several dis-aggregated data clusters that connect to the Internet through a firewall and load-balancer. Each dis-aggregated data cluster has several dis-aggregated compute/switch/disk chassis that are connected together by a mesh of Ethernet links. Each dis-aggregated compute/switch/disk chassis has many processing nodes, disk nodes, and I/O nodes on node cards that are inserted into the chassis. These node cards are connected together by a direct interconnect fabric. Using the direct interconnect fabric, remote I/O and disk nodes appear to the operating system to be located on the local processor's own peripheral bus. A virtual Ethernet controller and a virtual generic peripheral act as virtual endpoints for the local processor's peripheral bus. I/O and disk node peripherals are virtualized by hardware without software drivers. Rack and aggregation Ethernet switches are eliminated using the direct interconnect fabric, which provides a flatter, dis-aggregated hierarchy. | 08-27-2009 |

| 20120327766 | LEVEL OF HIERARCHY IN MST FOR TRAFFIC LOCALIZATION AND LOAD BALANCING - In one embodiment, a multiple spanning tree (MST) region is defined in a network, where the MST region includes a plurality of network nodes interconnected by links. A MST cluster is defined within the MST region, where the MST cluster includes a plurality of network nodes selected from the plurality of network nodes of the MST region. A network node of the MST cluster generates one or more MST bridge protocol data units (BPDUs) that present the MST cluster as a single logical entity to network nodes of the MST region that are not included in the MST cluster, yet enables per-multiple spanning tree instance (per-MSTI) load balancing of traffic across inter-cluster links that connect network nodes included in the MST cluster and network nodes of the MST region that are not included in the MST cluster. | 12-27-2012 |

| 20110268019 | USING JOINT DECODING ENGINE IN A WIRELESS DEVICE - A method for using a joint decoding engine in a wireless device is disclosed. A first symbol stream and a second symbol stream in a received multiple input multiple output (MIMO) signal is determined. A scaled channel estimate for a wireless transmission channel and a scaled noise covariance of the MIMO signal are also determined. The scaled channel estimate and the first symbol stream are whitened. Max log maximum a posteriori (MLM) processing is performed on the whitened first symbol stream to produce a first data stream. The first data stream may be de-rate matched and decoded to produce a decoded first data stream. | 11-03-2011 |
