Abstract
A method of managing a call traffic includes determining when a load of a first call manager exceeds a predetermined load level, and ameliorating the load when the load exceeds the predetermined load level. The load is ameliorated by either notifying a network that future calls are to be directed to a second call manager, or transferring at least one pending call from the first call manager to a second call manager, or both.
Claims16
Apparatus for use in an Internet Protocol (IP) telephony network operated by a service provider, the apparatus comprising
- a first call manager adapted to communicate with customer premises equipment served by said network in order to carry out processing necessary for the set-up of voice calls over said IP network,
- a second call manager adapted to communicate with customer premises equipment served by said network in order to carry out processing necessary for the set-up of voice calls over said IP network, and
- call manager logic that, in response to a determination that the processing load of said first call manager in carrying out said processing has exceeded a predetermined load level, offloads at least a portion of the processing load of said first call manager to said second call manager,
- the processing carried out by said first and second call managers including communicating messages to and from other equipment within said service-provider-operated IP telephony network.
A method for use in an Internet Protocol (IP) communications network of a type that includes a first call manager adapted to communicate with customer premises equipment served by said network in order to carry out processing necessary for the set-up of calls over said network, the processing carried out by said first call manager including communicating messages to and from other equipment within said service-provider-operated IP telephony network, the method comprising
- offloading at least a portion of the processing load of said first call manager to a substantially similar second call manager in response to a determination that said first call manager is in an overloaded processing condition.
