High-availability through shared IP

High-availability is achieved by automatic shared IP address transfer in case if current node, which possesses shared IP address, goes offline.

Requirements

  • node count: 2+
  • IP addresses count = node count + 1
  • nodes should be in one physical network

Advantages

  • shared IP address automatically transfers to one of other nodes if current node fails.
    Therefore, there will be no noticed denial of service, besides dropping a current call.
