The present invention can adjust the ratio between a global namespace storage area and a local namespace storage area. Each of the nodes adjusts the ratio between GNS storage areas and LNS storage areas of logical volumes according to the operating condition. When received a LNS-based access request as an access request for storing business affair data from each client, each of the nodes store the business affair data in their own LNS storage areas. When received a GNS-based access request, the node checks the unused capacity of the GNS storage areas of each of the nodes, and transfers the business affair data via a network switch to the node which comprises a logical volume with the largest unused capacity.

Asynchronous network interface and method of synchronisation between two applications on different computers is provided. The network interface contains snooping hardware which can be programmed to contain triggering values comprising either addresses, address ranges or other data which are to be matched. These data are termed “trip wires”. Once programmed, the interface monitors the data stream, including address data, passing through the interface for addresses and data which match the trip wires which have been set. On a match, the snooping hardware can generate interrupts, increment event counters, or perform some other application-specified action. This snooping hardware is preferably based upon Content-Addressable Memory.The invention thus provides in-band synchronisation by using synchronisation primitives which are programmable by user level applications, while still delivering high bandwidth and low latency. The programming of the synchronisation primitives can be made by the sending and receiving applications independently of each other and no synchronisation information is required to traverse the network.

A distributed DNS network includes a central origin server that actually controls the zone, and edge DNS cache servers configured to cache the DNS content of the origin server. The edge DNS cache servers are published as the authoritative servers for customer domains instead of the origin server. When a request for a DNS record results in a cache miss, the edge DNS cache servers get the information from the origin server and cache it for use in response to future requests. Multiple edge DNS cache servers can be deployed at multiple locations. Since an unlimited number of edge DNS cache servers can be deployed, the system is highly scalable. The disclosed techniques protect against DoS attacks, as DNS requests are not made to the origin server directly.

A transmit packet generated by a CPU 1 is held in a buffer 100a (100b). From among packets received from Ethernet 820a (820b), a packet, a destination of which is a communication device 800, is held in the buffer 100a (100b). A packet which should be transmitted is transmitted from a transfer judging circuit 200 to Ethernet 820a or 820b through a MAC unit 300a or 300b. If a transfer judging circuit 200 judges a packet from the Ethernet 820a to be a packet, a destination of which is another communication device, with reference to a destination MAC address, this packet is transferred to the Ethernet 820b through MAC 300b. If a usage rate of a transferring FIFO buffer 130a (130b) exceeds a threshold value in the process of transmitting a packet held in a transmitting FIFO buffer 120a (130b) on a priority basis, the priority order of a transfer packet is made higher than that of a transmit packet so that the transfer packet is transferred to the Ethernet 820a or 820b in preference to the transmit packet. This prevents a transfer buffer means from overflowing.

Mechanisms are provided for performing efficient compression and deduplication of data segments. Compression algorithms are learning algorithms that perform better when data segments are large. Deduplication algorithms, however, perform better when data segments are small, as more duplicate small segments are likely to exist. As an optimizer is processing and storing data segments, the optimizer applies the same compression context to compress multiple individual deduplicated data segments as though they are one segment. By compressing deduplicated data segments together within the same context, data reduction can be improved for both deduplication and compression. Mechanisms are applied to compensate for possible performance degradation.

This invention involves tracking and backing all the information that a user generates on its computer devices (including embedded devices) in real time. The local user server records all user actions and gestures (via various means that include TV cameras). All of this information (user actions and saved files in a computer) is then sent to a remote server via the Internet. This remote server has a virtual map of all the embedded devices on a computer that the person uses. The remote server immediately starts to interpret the user's actions (including user gestures). In one implementation, the invention stores user actions that are related to data generation (e.g. actions that called some links where data is stored, or executed some programs that generated data). In another variant the remote server generates and downloads the same files that are downloaded on the local user computer devices. For example, if a person begins to download a program, the server may also download the same program on a remote backup server. This way, if the user loses this program, it can be retrieved automatically through a provided server on the Internet. If user's files are backed up by regular backup periodically, relevant data that were stored by real time backup servers can be eliminated.

When a substrate is transferred by a holding arm to a multiple tier wafer boat, contact between the holding arm and the substrate is prevented. When the wafer boat is not subjected to a thermal effect, a normal height position of a ring member is obtained by relatively elevating and lowering a transfer base member with respect to the wafer boat. Before a wafer, which is not yet thermally processed, is transferred to the wafer boat, a height position of the corresponding ring member is obtained. By comparing a difference between the normal height position of the ring member and the height position of the ring member before the wafer is transported, with a threshold value, whether to transfer the wafer by the wafer transfer mechanism to the wafer boat can be judged.

Enhanced performance is achieved by combining channel coding with the space-time coding principles. With K synchronized terminal units transmitting on N antennas to a base station having M≧K receive antennas, increased system capacity and improved performance are attained by using a concatenated coding scheme where the inner code is a space-time block code and the outer code is a conventional channel error correcting code. Information symbols are first encoded using a conventional channel code, and the resulting signals are encoded using a space-time block code. At the receiver, the inner space-time block code is used to suppress interference from the other co-channel terminals and soft decisions are made about the transmitted symbols. The channel decoding that follows makes the hard decisions about the transmitted symbols. Increased data rate is achieved by, effectively, splitting the incoming data rate into multiple channels, and each channel is transmitted over its own terminal.

An autonomous controller allows an AC induction motor to operate over a broad range of AC power supply frequencies by reducing the amount of current supplied to the motor at lower frequencies. The controller detects the frequency of the power supply and switches the supply current on and off during each AC cycle to limit the RMS current to a value that is related to the detected frequency. Alternatively, the controller switches capacitive reactance into the power supply circuit which reduces the current supplied to the motor at lower AC frequencies.
