Abstract: Processes and systems are disclosed for creating and for managing trouble tickets and work orders. One embodiment includes communicating with a communications network and receiving a request to create a work order. The work order is initiated and identified with a work order number. The work order number includes a telephone number experiencing the problem. The work order is then distributed to clients, and the work order is identified and tracked using a customer's telephone number. A trouble ticket is similarly managed, with the trouble ticket describing a problem in a communications system. Here the trouble ticket is initiated and the work item number is assigned. The trouble ticket is then distributed to clients, and the trouble ticket is identified and tracked using a customer's telephone number.

Abstract: Improved systems and methods for implementing data-driven protocols are provided. In one embodiment, improved implementations of multicast routing protocols are provided. Separation between multicast forwarding and control elements are provided by use of a powerful yet simple application program interface (API) for inter-module communication. The API is multicast-routing-protocol-independent and can be used to express the forwarding state of any existing multicast protocol. Efficient platform-specific implementations are facilitated.

Abstract: A zone locking system detects unauthorized network usage internal to a firewall. The system determines unauthorized network usage by classifying internal hosts inside a firewall into zones. Certain specified zones are unauthorized to initiate client communications with other selected zones. However, zone override services can be designated for each associated internal zone, and thus, authorizing selected network services. An alarm or other appropriate action is taken upon the detection of unauthorized network usage.

Abstract: A messaging scheme to synchronize processes within a distributed memory multiprocessing computer system having two or more processing nodes interconnected using an interconnect structure of dual-unidirectional links. Each unidirectional link forms a point-to-point interconnect to transfer packetized information between two processing nodes. A lock acquisition request from a lock requesting node is placed into service by an arbitrating node when no previous lock requests are pending for service. The arbitrating node transmits a broadcast message to all nodes in the system, which, in turn, respond with a corresponding probe response message to inform the arbitrating node of cessation of issuance of new requests by the node sending the probe response message. The arbitrating node informs the lock requesting node of the requesting node's lock ownership by transmitting a target done message thereto.

Abstract: Embodiments of the invention include an access policy enforcement system for a system that provides services to other devices. As a service-providing device changes environments, or mobile states, access to the device's services is automatically and transparently limited or expanded. One aspect of the access policy determines the particular state in which the service-providing device is operating. Another aspect uses the determined state to dictate which services will be available to other devices.

Abstract: A system for supplying streaming media or other media sources to clients, where said system minimizes the lag time perceived by the user during negotiation between media sources by outputting the media content remaining in the buffer while the system is negotiating connection and buffering information from a second media source.

Abstract: A tracking manager, in communication with a status tracking structure and one or more client, provides event information regarding a plurality of objects, received from the status tracking structure, and alert information to the clients. Immediate rules and periodic rules are assessed in light of event information, which rules are stored in a rule storage component such that any of the rules may be modified independently of a rule execution component within the tracking manager. When the conditions defining any of the business rules are met, alert events are generated, stored and provided to the clients. Additionally, a map control operating in the clients allows selected portions of the event information to be provided to the clients. A data structure corresponding to a map schema is provided such that specialized map images may be readily provided and associated with each other.

Abstract: A system comprises a first node that provides a broadcast request for data. The first node receives a read conflict response to the broadcast request from the first node. The read conflict response indicates that a second node has a pending broadcast read request for the data. A third node provides the requested data to the first node in response to the broadcast request from the first node. The first node fills the data provided by the third node in a cache associated with the first node.

Abstract: Mechanisms for measuring network availability are described. A first network element produces a first knowledge digest encoding the first set of forwarding policy indicators associated with a set of packets into a fixed length bit array. The first network element periodically sends probe messages containing the knowledge digest to a second network element. The second network element produces a second knowledge digest encoding a second set of forwarding policy indicators into a fixed length bit array. The second network element compares the first knowledge digest to the second knowledge digest to determine whether the first set of forwarding policy indicators is a subset of the second set of forwarding policy indicators. The second network element indicates the availability of the path as long as probe messages are received from the first network element.

Abstract: A plurality of servers for processing client requests forward the requests among themselves to achieve a balanced load. When a server initially receives a client request, it randomly selects another of the plurality of servers, referred to as a first-chance server, and forwards the request to this server. Upon receiving the request, the first-chance server determines if it is overloaded and if not, processes the request. However, if overloaded, the first-chance server compares its load to the load of one or more predetermined next-neighbor servers. If the next-neighbor server(s) are more loaded than the first-chance server, the first-chance server processes the request. Otherwise, the first-chance server forwards the request to the least loaded next-neighbor server. The next-neighbor receiving the request either processes it directly, or alternatively, based on its current load and that of its next-neighbor server(s), forwards the request to another next-neighbor server for processing.

Abstract: A mechanism for making changes consistently across an application server domain or a cluster. Server configuration consistency is absolutely necessary for cluster deployments. The invention allows changes to the configuration repository and to the application deployment process to be managed via a Data Replication Service (DRS). The former requires that the configuration repository be version aware, while the latter breaks down the application deployment process into two phases—one for data distribution and processing as far as possible, and the second to expose the changes through the Java Naming and Directory Interface (JNDI).

Abstract: To reduce the load on a management server in a load distributed system, a server list manager 16 of a management server 10 selects servers 4, 6, 20, and 30 to be accessed by a client terminal management server 43 by referencing an operation status or a load status of the servers 4, 6, 20, and 30, generates a server list, and sends the generated server list to the client terminal management server 43. An inquiry unit 47 of the client terminal management server 43 regularly sends an inquiry to the network monitoring server 30, which is included in the server list 45, to ascertain whether or not information has been updated. If the information has been updated, an information collection unit 48 acquires a corresponding latest module and a rule base from the information providing server 20 included in the server list 45 based on information from the network monitoring server 30.

Abstract: A system for sharing block data includes a non-removable device for storing block data (e.g. a hard drive) that is networked with a plurality of computers. Each computer can initiate discovery commands and read/write commands, and transmit these commands over the network to the non-removable storage device. Computer commands are intercepted and processed by a logical algorithm program at the storage device. One function of the logical algorithm program is to instruct each computer to treat the non-removable block storage device as a removable block device. Because the computers treat the storage device as a removable block device, they relinquish control of the device (after use) to other computers on the network. The logical algorithm program also functions to allocate temporary ownership of the block storage device to one of the computers on the network and passes temporary ownership from computer to computer on the network.

Abstract: A method includes receiving a machine readable file containing a document that is to be served to a client for display on a client device, the organization of each of the documents in the file being expressed as a hierarchy of information, and deriving subdocuments from the hierarchy of the information, each of the subdocuments being expressed in a format that permits it to be served separately to the client using a hypertext transmission protocol, at least one of the subdocuments containing information that enables it to be linked to another one of the subdocuments.

Abstract: Bandwidth usage in a radio communication device is readjusted to eliminate overlapping communication system bandwidth. The readjustment is made in consideration of communication channel quality and other activity in the spectrum in which the radio communications are desired. Using this information, a communication link is set up to avoid overlapping with other radio communications already present in the band. Frequencies at which significant degradation in the communication occurs are also avoided. In addition, for frequency hopping devices, hop sequence is readjusted in accordance with the newly assigned channels.

Abstract: A service management system for determining a set of network elements constituting a possible cause of degraded quality of one or more services determines the quality of other services and determines the set as a function of the quality of the other services and network elements utilizing the other services.
