Conference call resource assignment for failover
In one example, a method for a conference bridge failover in a conference call system may include determining that a first conference bridge with a connection for a participant telephone has failed. The method may also include determining whether one or more conference bridge have resources to manage the connection for the participant telephone of the first conference bridge and assigning the connection for the participant telephone to the one or more conference bridge in response to the determination.
1. One or more non-transitory computer-readable media (CRM) having instructions executable by one or more processors to perform a conference bridge failover in a conference call system, the instructions to perform:
determining that a first conference bridge with at least one connection to a conference call for at least one participant telephone has failed;
in response to determining that one or more other conference servers in the conference call system are conference bridges for the conference call, and that a conference server having the most free resources of the one or more other conference servers has sufficient resources to manage all connections to the conference call handled by the first conference bridge, assigning all the connections to the conference call handled by the first conference bridge to the conference server having the most free resources;
otherwise, in response to determining that multiple other conference servers in the conference call system are conference bridges for the conference call, that the conference server having the most free resources of the multiple other conference servers does not have sufficient resources to manage all connections to the conference call handled by the first conference bridge, and that the multiple other conference servers collectively have sufficient resources to manage all connections to the conference call handled by the first conference bridge, distributing the connections to the conference call handled by the first conference bridge among the multiple other conference servers;
otherwise, in response to determining that multiple other conference servers in the conference call system are conference bridges for the conference call, that the conference server having the most free resources of the multiple other conference servers does not have sufficient resources to manage all connections to the conference call handled by the first conference bridge, that the multiple other conference servers collectively do not have sufficient resources to manage all connections to the conference call handled by the first conference bridge, and that another conference server in the conference call system that is not a conference bridge for the conference call has available resources to act as a new conference bridge, assigning at least some of the connections to the conference call handled by the first conference bridge to the new conference bridge;
otherwise, in response to determining that no other conference servers in the conference call system are conference bridges for the conference call, and that another conference server in the conference call system has available resources to act as a new conference bridge, assigning at least some of the connections to the conference call handled by the first conference bridge to the new conference bridge; and
otherwise, in response to determining that no other conference servers in the conference call system are conference bridges for the conference call, and that no other conference server in the conference call system has available resources to act as a new conference bridge, informing the at least one participant telephone that the at least one connection to the conference call cannot be continued.
2. The CRM of claim 1 , wherein at least one of the one or more conference bridges to which the at least one connection is reassigned is located in a site of the first conference bridge.
3. The CRM of claim 1 wherein at least one of the one or more conference bridges to which the at least one connection is reassigned is in a sub-network of the first conference bridge.
4. The CRM of claim 1 , the instructions further to perform:
the one or more assigned conference bridges to which the at least one connection is reassigned updating one or more other conference servers or one or more other conference bridges with update information characterizing the assignment.
