摘要： A method and apparatus for electing broadcast relay nodes (520B, H, M) in an ad hoc network (500). Each node (520A-520O) generates an attribute message including associated parameters. Each node (520A-520O) generates a weighted value (WV) based on the parameters. The WV can be included in the attribute message for that node, can provide a metric for ranking that node to be nominated to be a broadcast relay node, can alternatively provide a probability measure for that node to probabilistically elect itself as a broadcast relay node. The broadcast manager node (520C) receives the attribute messages and elects at least one nominated node as a broadcast relay node (520B, H, M) based on the attribute messages. Each node (520A-520O) can also initiate election of an intermediate broadcast relay node if that node fails to receive a test message within a predetermined time.
摘要翻译：一种用于在自组织网络（500）中选择广播中继节点（520B，H，M）的方法和装置。每个节点（520A-520O）生成包括相关参数的属性消息。每个节点（520A-520O）基于参数生成加权值（WV）。可以将WV包括在该节点的属性消息中，可以提供用于对要被指定为广播中继节点的节点进行排名的度量，或者可选地为该节点提供概率选择自身作为广播中继节点的概率测量。广播管理器节点（520C）基于属性消息接收属性消息并选择至少一个指定节点作为广播中继节点（520B，H，M）。如果节点在预定时间内未能接收到测试消息，则每个节点（520A-520O）还可以启动中间广播中继节点的选择。

摘要： Broadly speaking, an apparatus for efficiently utilizing a shared packet buffer memory in a switch and a method for operating the same is provided. More specifically, the apparatus includes a memory having a number of buffers configured to be operated in a ratcheted manner. The ratcheted manner in which the memory is operated causes each incoming data stream to be distributed across the number of buffers. Each stored data stream can also be retrieved from the number of buffers for output from the memory in a similar ratcheted manner. The memory uses a rotating selector to control the ratcheted manner of operation. Also, the memory is capable of simultaneously servicing each of a number of inputs and a number of outputs to which the memory is connected.

摘要： Techniques for preserving data in a data storage system are described herein. In one aspect, when a command to preserve data in a data storage system is received, a first input and output (I/O) process is executed in the data storage system which exists at a selected time relative to the command. A second I/O process is executed in the data storage system which begins after the selected time. The second I/O process being capable of executing while the first I/O process is executing, wherein the second I/O process is capable of accessing the same data, in the data processing system, as the first I/O process. Other methods and apparatuses are also described.

摘要： A non-volatile data cache having a cache memory coupled to an external power source and operable to cache data of an external data device such that access requests for the data can be serviced by the cache rather than the external device. A non-volatile data storage device is coupled to the cache memory. An uninterruptible power supply (UPS) is coupled to the cache memory and the non-volatile data storage device so as to maintain the cache memory and the non-volatile storage device in an operational state for a period of time in the event of an interruption in the external power source.

摘要： Broadly speaking, a device for addressing a shared resource is disclosed. The device includes at least one register in communication with the shared resource. The at least one register is configured to hold an address that is to be provided to the shared resource upon receipt of a clock signal. The device also includes a multiplexer for providing a next address to the at least one register. The multiplexer is disposed outside of a critical timing path for addressing the shared resource. The device for addressing the shared resource allows multiple users to be connected to the shared resource without adversely affecting both a speed of the shared resource and a number of users that can be achieved in an actual implementation of the shared resource.

摘要： Embodiments of the present invention provide methods and systems for data movement in data storage systems. For one embodiment, a physical data storage parcel containing a first type of data requiring a first type of processing and a second type of data requiring a second type of processing is created. The first type of data is transferred to a first memory address space via a direct memory access operation and the second type of data is transferred to a second memory address space via the direct memory access operation. For one embodiment, the first type of data and the second type of data are copied to physically distinct data storage mediums. In an alternative embodiment, the first type of data and the second type of data are copied to distinct data storage structures of the same device. Thus, the bulk memory access operations are performed via hardware, thereby reducing performance impact.

摘要： Broadly speaking, a bandwidth matching device is provided for transforming a number of incoming data streams each having a first bandwidth into an outgoing data stream having a second bandwidth. More specifically, the bandwidth matching device provides an assembler and a disassembler. The assembler incorporates a stepped arrangement of cells for transforming the number of incoming data streams having a given bandwidth into an outgoing data stream having a larger bandwidth, wherein each portion of the outgoing data stream represents a concatenation of a number of portions of each of the incoming data streams. As a complement to the assembler, the disassembler uses a stepped arrangement of cells to transform the concatenated output generated by the assembler back into the number of incoming data streams originally received by the assembler.
