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.
