Abstract: A method, apparatus, and computer-readable medium for predicting the fault-proneness of code units (files, modules, packages, and the like) of large-scale, long-lived software systems. The method collects information about the code units and the development process from previous releases, and formats this information for input to an analysis stage. The tool then performs a statistical regression analysis on the collected data, and formulates a model to predict fault counts for code units of the current and future releases. Finally, the method computes an expected fault count for each code unit in the current release by applying the formulated model to data from the current release. The expected fault counts are used to rank the release units in descending order of fault-proneness so that debugging efforts and resources can be optimized.

Abstract: Reducing connection overhead in a communications network includes reusing at least one cached communication channel connecting a source and a destination. The at least one cached communication channel is cached for a variable duration.

Abstract: A method for using broadband network resources includes providing simultaneous access to an asynchronous transfer mode switched virtual circuit for a plurality of sessions.

The method also comprises transmitting at least a first portion of the non-live content stream using the multicast source server and at least a second portion of the non-live content stream using the unicast source server. Also, the invention relates to a system comprising a multicast source server adapted to transmit at least a first portion of the non-live content stream in response to transmission of an initial meta-file. The initial meta-file is transmitted in response to receiving a request for a non-live content stream.

Abstract: A system and method are provided for reviewing and updating a subscriber's telecommunications services using a graphical user interface via multiple data networks. A data message is received at an intelligent peripheral from the graphical user interface via at least one of the data networks. The data message indicates a subscriber's desired update to a selected service. The data message is converted into a protocol compatible with a service control point. The converted data message is identical to a data message that the intelligent peripheral would create if the subscriber had entered the desired update via an interactive voice response system. The converted data message is transmitted to the service control point, which updates the service in accordance with the subscriber's update. Thus, the service is updated substantially contemporaneously with the request. Moreover, the subscriber retains the ability to update and review service data via the interactive voice response.

Abstract: Virtual circuits are dynamically established in a telecommunications network. A cache duration is adaptively determined based on at least one characteristic of the telecommunications network. A virtual circuit is established for a connection between a source and a destination. The virtual circuit is cached when the connection between the source and the destination terminates. The cached virtual circuit is reused when a new connection request occurs during the cache duration. The cached virtual circuit is released after the cache duration when no new connection request occurs during the cache duration.

Abstract: A communication network element determines a service provider's routing preference for routing communications and routes these communications from an originating connection address to a destination connection address over a network. The communication network element includes a receiver configured to receive a signal, which comprises the originating connection address and the destination connection address. The communication network element also includes a processor that determines the service provider associated with at least one of the originating connection address and the destination connection address of the received signal. The processor also determines the routing preference associated with the service provider using routing data.

Abstract: A system, method and computer readable media for detecting and managing fault within a network using the network's label distribution protocol transactions. Initially, the system will monitor and analyze all transactions within the network to determine if the network has degraded at or between any nodes in the system. The system can then recognize if there is any failure and determine if the network has degraded past a threshold value that is needed for proper operation. If the network has a failure that is beyond this threshold, it will notify a fault management system and subsequently a ticketing system to notify the user that a failure within the system has occurred.

Abstract: A method and system for allowing users to control the operation of hyperlinks includes a graphical user interface that displays Internet and intranet hyperlinks from web sites. The graphical user interface includes a selectable button that accepts user settings. The user settings allow the users to determine the operation of the hyperlinks so that the hyperlinks either open in a new browser window or in an existing browser window when selected by the user. An interface engine generates the selectable button on the graphical user interface, examines the selectable button for any user settings, and controls the operation of the hyperlinks based upon the user settings.

Abstract: Disclosed are systems, methods and computer-readable media for enabling speech processing in a user interface of a device. The method includes receiving an indication of a field and a user interface of a device, the indication also signaling that speech will follow, receiving the speech from the user at the device, the speech being associated with the field, transmitting the speech as a request to public, common network node that receives and processes speech, processing the transmitted speech and returning text associated with the speech to the device and inserting the text into the field. Upon a second indication from the user, the system processes the text in the field as programmed by the user interface. The present disclosure provides a speech mash up application for a user interface of a mobile or desktop device that does not require expensive speech processing technologies.

Abstract: A method and system are disclosed for operating a high speed data stream management system which runs a query plan including a set of queries on a data feed in the form of a stream of tuples. A predicate prefilter is placed outside the query plan upstream of the set of queries, and includes predicates selected from those used by the queries. Predicates are selected for inclusion in the prefilter based on a cost heuristic, and predicates are combined into composites using a rectangle mapping heuristic. The prefilter evaluates the presence of individual and composite predicates in the tuples and returns a bit vector for each tuple with bits representing the presence or absence of predicates in the tuple. A bit signature is assigned to each query to represent the predicates related to that query, and a query is invoked when the tuple bit vector and the query bit signature are compatible.

Abstract: A method and system for detecting routing loops and time-to-live (TTL) expiry attacks in a telecommunications network are disclosed. The detection of routing loops and TTL expiry attacks can be achieved based on the comparison of TTL expiries occurring on two or more routers in the network. A quantity of TTL expiries associated with a router can be summed. Additionally, a quantity of TTL expiries associated with other routers that are operatively coupled to the router can be summed. A difference between the sums can be calculated and a determination of whether a routing loop exists can be made in response to the difference.

Abstract: A method and system allow a subscriber to test emergency 911 telephone services routed from the subscriber's location over a network to a response center.
