Abstract: Methods and systems for detecting IP route failure using a request-reply protocol, such as address resolution protocol (ARP), and for dynamically re-routing VoIP sessions in a VoIP device in response to failure of an IP route are disclosed. A plurality of IP routes are established between a first VoIP device and a second VoIP device. VoIP sessions are assigned to the IP routes. ARP is used to detect a failure of an IP route. In response to detecting a failure of at least one IP route, VoIP sessions are rerouted from the failed IP route to an alternate IP route.

Abstract: A distributed architecture computing system includes one or more processors and object-oriented control program for processing request-type and response-type messages provided by a messaging service. The request-type messages are associated with one or more newly requested operations, and the response-type messages are associated with previously requested operations. The control program for the distributed architecture computing system includes a common server object for receiving and processing the request-type and response-type messages, and a specialized factory object for receiving the request-type messages from the common server object and creating a specialized request object for processing each of the request-type messages. Each of the request objects includes process request and process response methods for performing the requested operation, maintaining state information associated with the requested operation and generating the response-type messages.

Abstract: A method is disclosed for configuring software for acquiring PM data from telecommunication equipment in response to PM signals generated by the equipment responsive to events, including the steps of maintaining a library of product-independent, event-responsive modules, maintaining product-dependent data relating selected ones of the modules with a plurality of telecommunication equipment systems, and generating event-responsive PM software corresponding to one or more of the telecommunication equipment systems by assembling the modules in accordance with the product-dependent data.

Abstract: A method is disclosed for packaging and collecting PM data generated in PM data modules having current and previous data banks as a source of PM data during a monitoring interval, including the steps of receiving a demarcation signal from a system timer indicating the expiration of the monitoring interval, sending a signal, responsive to the demarcation signal, to the PM data modules instructing each of the modules to swap data banks, reading the PM data located in the previous data bank representing the monitoring interval, optionally packaging the PM data into a single byte stream, sending an armed and ready message to a controller, receiving a request for bulk transfer of the PM data, transmitting the PM data in one bulk transfer to the controller, and resetting the system timer for a next monitoring interval.

Abstract: A method is disclosed for processing PM signals to be optionally applied to an accumulator PM data module for further analysis including the steps of monitoring first and second transmission line channels to detect events, generating first and second PM signals in response to the events, receiving the first and second PM signals in first and second delay modules, the first and second delay modules having first and second module values therein, and optionally applying, responsive to the second PM signal, the first module values to the accumulator PM data module so as to acquire PM data for collection, storage and analysis.

Abstract: A method for configuring software to monitor, generate, acquire, collect, store and analyze Performance Monitoring (PM) data from telecommunication equipment, includes the steps of maintaining a library of product-independent PM data processing modules maintaining product-dependent data relating selected ones of the processing modules with each of a plurality of telecommunication equipment systems, and generating PM software corresponding to one or more of the telecommunication equipment systems by assembling the processing modules in accordance with the product-dependent data.
