Abstract: A method in a node within network computing system for selecting a master network manager, wherein the first node is associated with a first priority. Requests are sent to the network computing system to discover other nodes within the network computing system. A second priority from the request is identified in response to receiving a response to one of the requests from another node within the network computing system. The first node shifts to a standby mode if it discovers a master subnet manager or the second priority is higher than the first priority. The first node shifts to a master mode if a response containing a priority higher than the first priority is absent in responses received by the first node and the first node has completed checking all other nodes in the network computing system.

Abstract: A system and a method for communicating coalesced rule parameters in a distributed computing environment are described. A plurality of packet validation devices are communicatively interposed between network routing points within the distributed computing environment. The packet validation devices apply parameterized rules to transiting network packet traffic. A plurality of processing tree nodes are configured into a concast tree. In a lowermost layer of the concast tree, each processing tree node collects and coalesces rule parameters from at least one packet validation device. In each successive layer of the concast tree, each processing tree node collects and coalesce the rule parameters from at least one processing tree node in a next lower layer of the concast tree. A control center assembles the coalesced rule parameters from each packet validation device in an uppermost layer of the concast tree.

Abstract: A method of connecting to a network through a portal computer. A seeking computer dials the communications ports of a portal computer until it locates a call-in port. A port ordering algorithm is used to identify the call-in port. Communications ports selected by the port ordering algorithm may be re-ordered. The seeking computer uses the selected call-in port to request that the portal computer coordinate the connection of the seeking computer to the network.

Abstract: In a server which receives a request of processing from a client, and returns a processing result of the request to the client, a result storing unit stores at least one processing result of at least one request. When a determination unit determines that no other request which is identical to a request received from a client has been processed, an execution unit executes processing of the request received from the client, and stores a result of the processing in the result storing unit. When the determination unit determines that another request which is identical to a request received from a client has already been processed, a transmission unit transmits to the client one of the at least one processing result corresponding to the request received from the client.

The Host Computer which contains an operating system, has a variety of peripheral device driver software installed to enable interacting with these peripheral devices via a parallel port, serial port, USB port, or other types of ports. Hence, when a peripheral device related command is executed, data is sent from the peripheral device driver software to the selected port on the Host Computer and is intercepted by another software unit, which may compress this data and subsequently diverts it to the portable device via modem.

Abstract: A technique for adding a participant to a network is provided. This technique allows for the simultaneous sharing of information among many participants in a network without the placement of a high overhead on the underlying communication network. To connect to the broadcast channel, a seeking computer first locates a computer that is fully connected to the broadcast channel. The seeking computer then establishes a connection with a number of the computers that are already connected to the broadcast channel. The technique for adding a participant to a network includes identifying a pair of participants that are connected to the network, disconnecting the participants of the identified pair from each other, and connecting each participant of the identified pair of participants to the added participant.

Abstract: An admission control system for a server including an admission controller that receives a stream of messages from one or more clients targeted for the server. The admission controller relays to the server the messages in the stream that correspond to a number of sessions already underway between the clients and the server. The admission controller also relays to the server the messages in the stream that do not correspond to sessions already underway if a hybrid and predictive admission control strategy using information provided by a resource monitor indicates that additional sessions can be handled by the server. The admission controller defers the messages otherwise.

Abstract: A system and method of pushing user-selected data items from a host system to a user's mobile data communication device upon detecting the occurrence of one or more user-defined event triggers is provided. The user may then move (or file) the data items to a particular folder within a folder hierarchy stored in the mobile data communication device, or may execute some other system operation on the data item. Software operating at the mobile device and the host system then synchronizes the folder hierarchy of the mobile device with a folder hierarchy of the host system, and any actions executed on the data items at the mobile device are then automatically replicated on the same data items stored at the host system, thus eliminating the need for the user to manually replicate actions at the host system that have been executed at the mobile data communication device.

Abstract: A queuing system, method and computer program product is provided for transferring electronic information over a data network, such as the Internet. A host or system administrator monitors host resources by preventing one or more host resource limits from being exceeded. Where a resource limit is reached, a queuing protocol is initiated with a client requesting data. The queuing protocol permits the client to enter a queue and wait until host resources may be allocated to service the data request. The queue is maintained by the host, which may provide periodic updates to the client regarding queue length, position and estimated wait time. Clients may advance through the queue in accordance with a first-in-first-out algorithm, or some alternative priority scheme. When a client reaches the head of the queue, host resources are checked. If sufficient resources are available to service the client request, they are allocated to the client at the head of the queue.
