摘要： Supporting distributed key-based processes is described. In an embodiment, servers at a data center provide a key-based process for carrying out computationally expensive tasks and are connected using point to point connections in a geometric topology such as a torus. In an example, aggregation trees are built on top of the geometric topology of the data center, each aggregation tree being a sequence of servers in the data center that forms a tree structure. In an embodiment packets of data are sent from the leaves of the trees to the root and at each server along the tree the packets are aggregated using a combiner function of the key-based process. In an embodiment, if a server fails, the trees are dynamically recomputed and a recovery phase is triggered to resend any packets lost at the failed server. In some embodiments, packets are scheduled by inspecting the content of the packets.

摘要： Content transfer between nodes in a communications network is required in many situations. For example, between fixed nodes in a data center, between a fixed node such as a base station and a mobile node such as a mobile telephone and between mobile nodes themselves such as personal digital assistants. In an embodiment a content transfer process for use between nodes where one node knows the size of content to be transferred is described. For example, a file is divided into blocks to be sent between the nodes. A node receiving a block keeps a record of the received blocks and sends that record to the sending node at certain times. By controlling the times at which the records are sent the number of messages that need to be sent to transfer the records is low and the blocks are transferred in an efficient manner.

摘要： Content discovery and content transfer between mobile communications nodes is often required, for example, to synchronize maps, traffic hot spot information and the like for vehicle mounted satellite navigation devices, pedestrian hand-held personal digital assistants and other mobile communications nodes. In an embodiment, content discovery processes using data structures designed in particular ways and sent using a single packet enable nodes to identify files to be transferred whilst keeping overheads down. In an embodiment a first and a second data structure are used, each being formed from slightly different information about a subset of the files to be synchronized. In another embodiment a single tree-based data structure is used. A process for transferring data between two mobile communications nodes is also described.
