Abstract: Wireless mesh networks (or “meshes”) are enabled for arbitrary interconnection to each other and may provide varying levels of coverage and redundancy as desired. Interoperability between meshes having differing configurations, internal operations, or both, may be freely intermixed and inter-operated in unrestricted combination. Enhanced explicit inter-bridge control protocols operate using pre-existing control packets. Pre-existing broadcast packet floods are used to learn the best paths across interconnected meshes (termed a “multi-mesh”). Enhanced routing protocols operating within each mesh may optionally examine information limited to the respective mesh when forwarding traffic, thus enabling robust multi-mesh scaling with respect to memory and processing time required by the routing protocols. Communication scalability is improved by enabling frequency diversity across the multi-mesh by configuring meshes within interference range of each other for operation at a plurality of frequencies.
Abstract: Storage gateway provisioning, configuration, and management functions provide mechanisms to specify and manage parameters and operations associated with storage gateways. The parameters may include any combination of VLAN topology, zoning behavior, LUN masking, bandwidth, and priority. The parameters may also include path information describing initiator to target associations, enabling load-balancing aggregations and multipathing redundancy. Parameters may be specified at relatively low-levels, describing specific HW elements, or may be specified at relatively high-levels, describing desired bandwidth and redundancy requirements, with SW determining low-level HW assignments. Configuration and management functions enable dynamic modification of storage gateway parameters (such as bandwidth between selected initiator and target pairs). Management functions also enable dynamic switchover from a primary path to a secondary path with respect to a storage device.

Abstract: Real time provisioning and management of fabric-backplane enterprise servers includes monitoring system status and configuration, displaying monitoring results, accepting user commands, and providing hardware and software management and configuration commands to the system. In one embodiment, an event is generated when a pluggable module is inserted into the system. In response to the event, the availability of the pluggable module is displayed to a system operator, and the operator enters a command to provision a server that includes the pluggable module. The server provisioning command is processed, resulting in a hardware configuration command being issued to the system, and an event indicating a status associated with processing the command is returned. The recognition of the inserted module, the display to the operator, and the processing of the server provisioning command occur in real time.
Abstract: A system, method, and computer program product are provided for reducing write operations in memory. In use, write operations to be performed on data stored in memory are identified. A difference is then determined between results of the write operations and the data stored in the memory. Difference information associated with the difference is stored in the memory. To this end, the write operations may be reduced, utilizing the difference information.
Abstract: A system, method, and computer program product are provided for increasing a lifetime of a plurality of blocks of memory. In operation, at least one factor that affects a lifetime of a plurality of blocks of memory is identified. Additionally, the plurality of blocks to write is selected, based on the at least one factor.
Abstract: A system, method, and computer program product are provided for providing data redundancy in a plurality of storage devices. In operation, a number of writes to a plurality of storage devices is reduced. Additionally, after the reducing, data redundancy is provided utilizing a data redundancy scheme.
Abstract: Individual wireless devices communicate amongst each other exchanging identity information, authentication-state or both, thereby forming a collaborative-collection of wireless devices. This collaborative-collection of wireless devices offers improvements over individual wireless devices in three areas. First, device functions are affected by the group of devices that are active-members of the collaborative-collection, enabling improved functionality. Second, the times-of-membership and times-of-non-membership of the devices in the collaborative-collection are monitored and this information is used to affect the function of individual devices in the collaborative-collection, including improved security and authorization policies. Third, the authentication-state of the active-member devices in the collaborative-collection affects the function of the active-member devices in the collaborative-collection, also adding to improved security.
Abstract: System, apparatus, and methods are disclosed wherewith a group of independent wireless routing devices known as Service Points work cooperatively to form an ad hoc mesh communication network. The resulting Service Point Network is used to provide reliable address-directed communication services between devices attached by conventional means (wired or wireless) to respective Service Ports on any of the Service Points. Attached Utilizing Devices are not considered a part of the Service Point Network and need not contain any custom software or hardware related to the operations of the Service Point Network. Consequently, the networking technology used to form the Service Point Network is independent of the technology used for connecting devices to Service Points. Services for Utilizing Devices include both point-to-point as well as point-to-multi-point communication.

Abstract: Portable computing hosts, such as PDAs, are customized for use in diverse applications, such as media and game players, through use of a first-level removable expansion module having player-specific circuitry and a slot for a second-level removable module, such as a removable memory. For example, in combination with a connected or attached user interface device (e.g., earphones), these modules provide a host with external-interface circuitry and/or application-specific functions as well as second-level removable memory functions. The removable memory may be used to store and playback digitally encoded media such as music, audio, or video. The removable memory may also be used directly or predominantly by the player's application specific circuitry within the first-level removable expansion module.
