Abstract: One embodiment of the present method and apparatus adaptive load shedding includes receiving at least one data stream (comprising a plurality of tuples, or data items) into a first sliding window of memory. A subset of tuples from the received data stream is then selected for processing in accordance with at least one data stream operation, such as a data stream join operation. Tuples that are not selected for processing are ignored. The number of tuples selected and the specific tuples selected depend at least in part on a variety of dynamic parameters, including the rate at which the data stream (and any other processed data streams) is received, time delays associated with the received data stream, a direction of a join operation performed on the data stream and the values of the individual tuples with respect to an expected output.

Abstract: A service monitoring mechanism for providing on-line standardized contract configurations for monitoring Service Level Agreements (SLAs) and Service Level Contracts (SLCs) is described. The service monitoring mechanism provides a method for monitoring a service level agreement that defines for a particular network, a level of service that has been offered to a customer by a service provider. In one aspect, to provide for the monitoring of a service level agreement, a Service Level Manger (SLM) is configured to manage, monitor, and verify the SLAs that have been established between a customer and a Service Provider. The SLM provides a standardized open interface that allows users, including third parties, to define SLCs and SLAs for monitoring and verifying the level of service that is being provided by a service provider.

Abstract: A network storage system where the network storages are connected to clients. The system is resistive to faults and enables to access using the NFS standard protocol and allows clients access without regard to the interface even when the process is executed on any network storage. When a client has issued an access request to a first network storage, the first network storage transfers the request to a directory server storing file management information. The directory server selects a second network storage to process the request and transfers the request to the second network storage. The second network storage processes the request and transmits a packet to the client as if the process had been executed in the first network storage.

Abstract: The CPU of a mail server accepts input of electronic mail. The CPU judges whether or not the mail has an attached file of a data capacity larger than a predetermined threshold value. If the mail is judged to have such an oversized attached file, the CPU generates key information (or a URL and a password). Then, the CPU writes the key information in association with a name of the attached file to a file ID table in a storage device. The CPU replaces the attached file with the key information. And, the CPU increments by 1 a counter value (N) representative of the number of times an attached file storage service has been used (N=N+1) The CPU outputs the attached file to a user-wise attached file storage area for storage therein. When the mail is not judged to have any oversized attached file or when the attached file is stored in the user-wise attached file storage, the CPU sends the electronic mail to a destination mail server.

Abstract: Methods and systems are provided for resolving an addressing conflict between a first processor in a first network and a second processor in a second network. When an addressing conflict is detected between a first address of the first processor and a second address of the second processor, tunnel information is removed from one or more packets received from the first processor. Based on the removed tunnel information, the packets are associated with the detected addressing conflict and a translated address is determined. Based on the translated address, the packets are then forwarded.

Abstract: A method for provisioning a network element is included where a custom default file and a standard default file are provided in a network element. The custom default file includes one or more default parameters of a same type, but having a different value from, corresponding default parameters in the standard default file. Service parameters are determined based on the default parameters of the standard default file as modified by overriding default parameters of the custom default file. The service is generated based on the service parameters.

Abstract: A reception apparatus includes a first timer and sends to a distribution apparatus a first date-time clocked by the first timer. The distributing apparatus includes a second timer, and generates expiry information based on a difference obtained by subtracting, from the first date-time, a second date-time that is clocked by the second timer. The expiry information is used to adjust a usage expiry date-time of content. The reception apparatus judges whether playback of the content is permitted based on the first timer and the expiry information. With this arrangement, unauthorized use of the content beyond the expiry date-time is prevented.

Abstract: A policy server operates to configure differentiated services over multi-protocol label switching (Diffserv/MPLS) in a communications network. The policy server enables the definition and deployment of a customer policy, a network policy and a mapping policy. The policy server is arranged to create a group of MPLS tunnels, and associate the tunnels to the mapping policy and the customer policy. The customer policy includes a tunnel group identifier and a tunneling mode, and maps customer traffic to MPLS tunnels. The policy server translates the customer policy, the network policy and the mapping policy into device-specific commands, and then deploys the device-specific commands to the network interfaces of the affected network devices.

Abstract: A local proxy that is located between a client device and a host system may be used to identify, or provide information about, a client device or identity using a client device that accesses a host system. The local proxy may append parental control information (such as a parental control level) to communications sent by the client device. The host system may provide, or restrict, access to information or features based on the information appended to communications sent by the client device. The local proxy and the host system both may store an additional copy of parental control information associated with one or more identities or client devices. The mirror copy of parental information may be used to restrict communications based on an identity or device's parental control classification and/or may be used to verify that parental control information has not been improperly modified or accessed. Parental controls may be applied using access control lists stored on the local proxy.

Abstract: A method of updating one or more target website data content items comprises providing one or more links, each of which associates one or more target content items with one or more original content items. The method further includes storing the links in a data storage device, and accessing the links in the storage device, and updating the target data content items according to the links. The method may update the target data content items at predetermined intervals, or on demand. Updating the target data content may further include initiating workflow to update the target data content.

Abstract: Methods and systems for dynamic, distributed link table consistency management are disclosed. A method for dynamic, distributed link table consistency management includes requesting, from each link interface module that maintains a link table in a distributed routing system, a link table checksum from the other link interface modules in the system. The requesting link interface module computes a checksum for its local link table and compares the computed checksum to the received checksums. In response to detecting a mismatch between the local checksum and one of the received link table checksums, the link interface module requests individual entry checksums from the link interface module with which a mismatch was detected. Inconsistencies between individual entries may be automatically corrected and/or reported to an operator.

Abstract: A system for gathering data for purposes of analyzing a network. The data is gathered based on values that are passed from node-to-node within processing devices, such as servers, in a network. The values are generated from characteristics obtained from measuring device performance and resource utilization. Values are passed peer-to-peer and successively combined with values at each receiving system so that, ultimately, a value is obtained that reflects the operation of a group of devices. A correlation matrix is maintained to indicate discrepancies in value meanings from different devices. The correlation matrix is used to more accurately combine values to achieve meaningful composite values.
