ABSTRACT:
The present invention enables network providers to create peering arrangements with other providers that allow them to fail over to other networks in the event of a site failure. This invention would lower the cost to provide site diversity within a provider's network by allowing cost sharing between the provider's network and other networks. For example, when an Application Server (AS) in a network fails, the network provider can send a call to a partner's network and uses an AS in the partner's network to process the call request.
