Abstract: Methods and systems are provided to automatically reroute logical circuit data. In accordance with an example method, a failure of a dedicated logical circuit in a packet-based network is identified. The dedicated logical circuit has a first logical circuit identifier assigned prior to identifying the failure. The dedicated logical circuit connects a host device to a remote device to communicate data that originates and terminates only at the host device and the remote device. A logical failover circuit comprising an alternate communication path for communicating the data is selected. When the first logical circuit identifier of the dedicated logical circuit does not match a second logical circuit identifier of the logical failover circuit, the second logical circuit identifier is renamed to match the first logical circuit identifier. The data is rerouted to the logical failover circuit without manual intervention.

Abstract: A method and system are provided for automatically rerouting logical circuit data from a physical circuit failure in a data network. When a failure in a logical circuit is detected, a label or services name associated with the logical circuit is automatically associated with a logical circuit identifier utilized for identifying the logical circuit in the 10 data network. Once the logical circuit is associated with the logical circuit identifier, the logical circuit data may be automatically rerouted to a “failover network,” thereby minimizing lost data until the failure in the logical circuit is resolved. The logical failover circuit may be an already existing logical circuit provisioned over a dedicated backup physical circuit in the data network.

Abstract: A method and system are provided for provisioning logical circuits for intermittent use in a data network. A customer order requesting the use of a logical circuit for communicating data for a predetermined time period is received in the data network. A logical circuit is then provisioned in the data network prior to the start of the predetermined time period for communicating the customer data. Once the predetermined time period has elapsed, the provisioned logical circuit is deleted from the data network.

Abstract: A method and system are provided for tracking the rerouting of logical circuit data in a data network. A disclosed example method involves updating reroute information in response to a dropped packet associated with a quality of service parameter having been exceeded. Transmitted data is rerouted to at least one logical failover circuit in the data network from at least one failed logical circuit associated with the exceeded quality of service parameter. The at least one logical failover circuit is selected based on a bit rate capability specified to be one of a committed bit rate, a variable bit rate, or an unspecified bit rate.

Abstract: A user agent in a Web access device transmits an HTTP request for Web content to an origin server. The request contains a set of capabilities of the Web access device. A content authoring mechanism and adaptation determination service on the origin server process the request to determine what transformation is required to make the requested content fit the capabilities of the Web access device. The adaptation determination service invokes a niche transformation service that performs, in response to the content and the capabilities, the necessary transformation. The transformed Web content is transmitted to the user agent.

Abstract: A method of storing collected data on a wireless device. User interaction with a wireless device and/or the performance of the wireless device is monitored and data related thereto collected. The collected data may be structured into a tagged hierarchical structure comprising a plurality of events that are separate and independent from one another. Each event may describe a specific application with a plurality of attributes. The tagged hierarchical structure formed as a tree structure is translated into a syntax generic language. The result may be formed into a compact format using a zipped format and/or a binary-equivalent format and then stored and transmitted to a central location (e.g., a server) for statistical analysis processing. The server transforms the received data into expanded format and forms a hierarchical tree structure for each event and its attributes. The result is processed for producing a statistical analysis of the collected data.
