Abstract: The present invention provides a rule set orchestration processing method and apparatus, and a cluster data system. The method includes: grouping, according to device information of each network device in a network, each network device, to obtain at least one network device group; selecting, for each network device group obtained after the grouping, at least one service rule matching the network device group, to form a rule set of the network device group; and sending a rule set of each network device group to each network device in the network device group separately. In the present invention, all network devices are grouped into at least one network device group according to device information, a matched rule is selected and sent for each network device group to form a rule set, so as to avoid repetitive processing and excessive processing on the rule set.

Abstract: A load balancer, comprising a network interface, a power conservation unit, and a routing module configured to route client requests received through the network interface to a plurality of servers. The power conservation unit is characterized by having a learning mode and a routing mode. In the learning mode one or more operation parameters of the servers are determined for a plurality of different external conditions and for a plurality of different values of one or more operation parameters of the routing module, and to generate a correlation table between the operation parameters of the routing module and the external conditions. In the routing mode the power conservation unit adjusts the operation parameters of the routing module responsive to the external conditions, using the correlation table.

Abstract: A method for file storage management. The method includes the steps of determining by a first computer, for a plurality of peer computers in a communication network of the first computer, information on the storage management of blocks of the file by the peer computers. In addition, the method includes selecting, by the first computer, blocks of the file to be made available to the first computer independently of the plurality of peer computers, responsive to the determined information and managing a storage unit of the first computer, such that the non-selected blocks of the file are not stored locally by the first computer.

Abstract: A method of resolving a plurality of database queries. The method includes accumulating a plurality of queries, determining overlapping portions of the queries that relate to one or more common data attributes, resolving at least two of the determined overlapping portions of the queries together, and preparing responses to the queries based on the resolution of the at least two overlapping portions.

Abstract: A database server accelerator, comprising a plurality of query execution machines, adapted to resolve database queries, a plurality of respective memory units, adapted to cache data from the database, each memory unit being accessible only by its respective execution machine, and a data-manager adapted to determine the data to be cached in each of the plurality of memory units.

Abstract: This invention discloses an apparatus for managing a switched routed network including a network configuration learning unit operative to learn a configuration of the switched routed network, a VLAN assignment unit for generating a division of the network into virtual LANs (VLANs) based on the learned configuration of the network; and a change manager operative to detect a change in the configuration of the network and to modify the division of the network into VLANs. A method for generating a division of a switched routed network into virtual LANs based on a learned configuration of the network is also disclosed.

Abstract: This invention discloses a method for detecting a layout of a switched local network including at least one switching hub connected to a first plurality of elements, each identified by an address, via a corresponding second plurality of ports defining a corresponding second plurality of element to port connections, the method including determining all element to port connections for each switching hub, identifying the elements which communicate via each of that switching hub's backbone ports and based on the element to port connections and the elements communicating via each switching hub's backbone ports, determining the layout of the switched local network.An apparatus for monitoring a layout of a local network, the network including a first plurality of ports associated, via end-station to port connections, with a second plurality of end-stations is also disclosed.
