Service broker
View Patent ↗The present invention relates to a service broker capable of dynamically provisioning media gateways, gateway controllers, and call servers when adding one or more of these elements to the network, or reconfiguring the network when an element fails or to balance loads. Based on defined guidelines or rules, the service broker can select gateway controllers for media gateways, call servers for gateway controllers, and backup elements for any of the above. Once selected, the service broker notifies all affected elements of their associations.
