    摘要： Described are embodiments for providing unique identifiers for files or objects across servers in a server cluster. Embodiments include generating a unique identifier that includes at least three portions. The first portion includes a node identifier which identifies the particular server in a cluster which created the unique identifier. The second portion includes a major sequence number that is incremented when a server is rebooted or otherwise taken off-line and then brought back online. Additionally, the major sequence number is incremented when all of the minor sequence numbers, which are included in a third portion of the unique identifier, have been used. The minor sequence numbers in the third portion are incremented for every unique file or object requested.

    摘要： Methods of providing access to data are presented. The method includes providing a storage grid which includes a source chain of storage nodes and a target chain of storage nodes, the source chain including a primary source node and a secondary source node which operates as a data mirror of the primary source node, and the target chain including a primary target node and a secondary target node which operates as a data mirror of the primary target node. The method also includes initially storing data on the source chain, the primary source node of the source chain maintaining a primary source copy of the data, and the secondary source node of the source chain maintaining a secondary source copy of the data. The method further includes relocating the data from the source chain to the target chain, the primary target node of the target chain maintaining a primary target copy of the data, and the secondary target node of the target chain maintaining a secondary target copy of the data, access to the data being continuously provided from the storage grid to an external device before, during, and after relocation of the data from the source chain to the target chain.

    摘要： The discovery process comprises the device (10) generating messages (112, 120 126) which together have the purpose of identifying a predetermined number of devices which satisfy a test condition included in each message. These messages are sent respectively to the on-line devices (12, 20, 26) neighbouring device (10). To ensure that no more devices than necessary are identified by the messages, each message includes a variable which is referred to as a token bucket which indicates the number of devices to be discovered by the message. Additionally, each message includes a unique identifier. When a device (12, 20 26) receives a discovery message sent from another device, it determines if it satisfies the test condition and if so it sends an acceptance message to the originating device, decrements the token bucket in the message and forwards on any remaining tokens to another neighbour. The process stops once all tokens have been disposed of in this way. If a message reaches the end of a path without disposing of all of the tokens, the message is returned back up the path to try different paths until eventually all paths have been tried or a restriction criterion (eg maximum permitted number of hops) is met whereupon the message is returned back as a failed message to the originating device.

    摘要： There is described a method of synchronization in a personal information­entertainment product (10) for periodically updating data content stored in memory (50) of the product (10). Moreover, apparatus (10), for example advanced personal information­entertainment products, capable of operating according to the method are elucidated. A system and software operable to implement the method are also disclosed. The method relates to data synchronization in a personal information-entertainment device (10) operable to present data content to a user (20) of the device (10), the method including steps of: (a) arranging for the device (10) to determine one or more contexts (410) in which it is to be used; and (b) updating data content stored in the device (10) in response to the one or more contexts (410).
