Abstract

A system for monitoring information real-time through a network. The system has a plurality of network elements Each of the network elements comprises an interface device. The plurality of network elements are configured to route a call from a source to a destination through the network elements. A mediator is coupled to each of the network elements. The mediator is adapted to receive events from any one of the network elements as the call as being routed through the elements from the source to the destination. A message bus is coupled to the mediator for receiving the events. The system also has an application process coupled to the messaging bus. The application process is adapted to use the events. The system is fault tolerant and information under process is not lost even when one of the system components fails.

Claims

1. A fault tolerant system for monitoring information real-time through a network, the system comprising:

a plurality of network elements, each of the network elements being coupled together in a network, each of the network elements comprising an interface device, the plurality of network elements being configured to route a call from a source to a destination through the network elements;

a plurality of mediator processes coupled to each of the network elements, the plurality of mediator processes number from 1 to N, where N is an integer greater than 1, each of the mediator processes being-configured to receive events from any one of the network elements as associated with the call as the call is being routed through the elements from the source to the destination; and

a distributor process coupled to each of the mediator processes, the distributor being configured to distribute incoming events for any one of the mediator processes that experiences a fault to the other 1 through N mediator processes excluding the mediator processes that has experienced a fault.

2. The system of claim 1 further comprising a correlation process coupled between the messaging bus and the mediator, the correlation process comprising a plurality of rules, each of the rules being-configured to change information received from the mediator to one of a plurality of call detail records, each of the call detail records being of a preselected format.

3. The system of claim 1 wherein the plurality of network elements comprise at least a router and one or more devices selected from a switch, a server, a Media Gateway, Softswitch, and an Integrated Access Device.

4. The system of claim 1 wherein the source is a caller location and wherein the destination is a receiver location.

5. The system of claim 1 wherein the plurality of mediator processes are respectively provided on a plurality of server devices, number from 1 through M, where M is equal to N.

6. The system of claim 1 wherein the distributor process selects one of the mediator processes for the incoming events associated with a single call.

7. The system of claim 1 further comprising a network interface coupled to the distributor process, the network interface being-configured to convert incoming events into a common protocol for use in any one of the mediator processes.

8. The system of claim 1 wherein the distributor process is provided in an adaptor.
