Call redundancy for a packet-based network

A method comprising:

• receiving at a receiver module in a media gateway in communication with a packet-based network data associated with a plurality of calls on one or more signaling links, the data including signaling information, the signaling information being Signaling System 7 signaling information;
• operating said receiver module to provide, the data associated with the plurality of calls to a first processor module of the media gateway and to a second processor module of the media gateway and a second processor module of the media gateway;
• operating the first processor module to:
• i) receive data associated with the plurality of calls from the receiver, ii) determine and maintain state information about the status of the one or more signaling links, iii) process the content and signaling information associated with the plurality of calls based on the state information, and iv) transmit said content information to a destination over the active communication link based on the signaling information processed by the first processor module;
• and
• operating the second processor module to:
• i) receive, in parallel with the first processor module, data associated with the plurality of calls from the receiver, ii) process at least a portion of the signaling information associated with the plurality of calls asynchronously and in parallel with the processing of the signaling information in the first processor module, iii) determine state information about the status of the one or more signaling links and to synchronize the determined state information with the state information maintained in the first processor, iv) maintain the synchronized state information, and v) maintain the content information associated with the plurality of calls.

A computer program product, tangibly embodied in a non-transitory computer-readable storage medium, the computer program product including instructions being operable to cause data processing apparatus in communication with a packet-based network to:

• receive, at a media gateway, data associated with a plurality of calls from one or more signaling links, the data including content information and signaling information, the signaling information being Signaling System 7 signaling information;
• operating said receiver module to provide, in parallel, the data associated with the plurality of calls, to a first processor module of the media gateway and to a second processor module of the media gateway and to a second processor module of the media gateway;
• operate the first processor module to i) receive data associated with the plurality of calls from the receiver, ii) determine and maintain state information about the status of the one or more signaling links, iii) process the content and signaling information associated with the plurality of calls based on the state information, and iv) transmit said content information to a destination over the active communication link based on the signaling information processed by the first processor module;
• and
• operate the second processor module to i) receive, in parallel with the first processor module, said data associated with the plurality of calls from the receiver, ii) process at least a portion of the signaling information associated with the plurality of calls asynchronously and in parallel with the processing of the signaling information in the first processor module, iii) determine state information about the status of the one or more signaling links and to synchronize the determined state information with the state information maintained in the first processor, iv) maintain the synchronized state information, and v) maintain the content information associated with the plurality of calls.
