Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F 1730

US Classification:

707 1, 709223, 709320, 709328, 345740, 345966

Abstract:

A command line interface for a network management platform includes a parser that parses and validates inputs entered at a command line, a command processor that, responsive to validation of a command, causes an operation specified by the command to be performed, and an output facility that presents outputs of the command line interface. The parser preferably enforces a syntax addressing a plurality of attributes of a network device as a tree-like hierarchy including at least two containers. The parser permits network device attributes, which are each contained in at least one container, to be contained by multiple containers of the same type so that such attributes are addressable via a plurality of different access paths. The output facility preferably provides one or more outputs for operations specified by processed input commands, and the one or more outputs preferably include at least one output command specifying a network management operation to be performed. To facilitate entry of valid inputs, the command line interface may be further equipped with an input assistance facility that causes the output facility to present, for a selected network device in the communication network, a prompt for each of a plurality of attribute names that specifies possible attribute values for the plurality of attribute names.

International Classification:

G06F 1338

US Classification:

345853, 345854

Abstract:

A command line interface for a data processing system includes an output facility that displays outputs to an operator, a parser that validates inputs entered a command line, a command processor that processes commands validated by the parser. The command line interface preferably supports a prompt mode in which the output facility displays an editable prompt that may be modified by the user to construct a command. In addition, the parser preferably defines separate validation and execution point inputs including at least one validation-only point input, so that inputs are permitted to span multiple input lines and so that atomic sets of commands can be constructed by entering multiple commands on a single input line. The command line interface is also equipped with an in-line help facility that, in response to the parser detecting a help request in a partial command entered at the command line, automatically presents possible input options that can be entered at the command line to complete the partial command.

International Classification:

US Classification:

707793, 707756, 707803, 717162

Abstract:

A method, system and computer program product for identifying one or more niche services to combine into a common service, wherein the niche service is a part of a service oriented architecture (SOA). The extensible markup language (XML) schema of the one or more niche services is aggregated into a combined XML schema, wherein the combined XML schema is the XML schema of the common service. A web services description language (WSDL) of the one or more niche services are aggregated to establish a combined WSDL, wherein the combined WSDL is the WSDL of the common service. The common service is generated from the combined XML schema and the combined WSDL. The combined WSDL, utilized to identify the combined service, comprises a service provider URL, one or more service operations, and combined XML schema. The combined XML schema is associated with a common service request and a common service response. When the XML schema of the niche service is not equal with the combined XML schema, mediation is invoked.

US Classification:

713168, 709207

Abstract:

A system, method, and computer program product for transmitting message traffic encapsulating a MQ network having a plurality of MQ clients coupled to a MQ queue via at least one MQ queue manager and at least one MQ proxy server coupled to the plurality of MQ clients. The at least one MQ proxy server retrieves a message from a first MQ client coupled thereto, evaluates the message content and forwards the message to the MQ queue via a designated MQ queue manager. If the destination MQ client is served by a second MQ proxy server the originating MQ proxy server notifies the second MQ proxy server coupled to the second MQ client. The second MQ proxy server retrieves the message from the MQ queue thru the designated MQ queue manager, evaluates the message content and forwards the message to the second MQ client. If the first MQ client and the second or destination MQ client are served by the same MQ proxy server, then the MQ proxy server will just retrieve the message from the MQ queue through the designated MQ queue manager and forward the message to the second MQ client.

Abstract:

Techniques disclosed herein include systems and methods for transmitting TV program related content to IP connected devices on a home network, or other local area network. Users can watch television while simultaneously receiving content related to TV programs currently being displayed on a television. TV centric and TV program related content can be transmitted to IP connected devices. Moreover, this TV program related content can be displayed at the same time as a television program is being displayed on a television. As such, the system can provide media synchronization within home network using the set-top box as a gateway for delivering the content. Users can watch TV at home, and at the same time receive TV program related content on a laptop, tablet computer, mobile phone, etc.

Abstract:

A new system and method allows a Manager in a Simple Network Management Protocol (SNMP) environment to gather updates from its Agents. The system and method comprise the unique provision of an index which is used in each of the Agent's tables for indicating the various revisions thereof. The index lexicographically increases with each revision to the table. The Manager maintains a record of the index of the data which it has received from its Agents, requesting only that data having a lexicographically larger indexing. Further, the index is used in related tables so that the tables will be kept in "sync" in that the Manager will know whether it has the latest updates so that an accurate picture may be portrayed.
