Abstract
Implementations for communicating network configuration and IP changes to protocol heads. An in-memory cache of currently available IP addresses and locations can be maintained via a registration and callback method. The registered protocol head will have its cache updated when the network configuration changes. The protocol head will also receive events indicating specific changes as they occur, and a callback can be registered to act upon certain configuration events. An additional event can be sent to the protocol head indicating intent to move IP addresses from one node to another. The provided information allows the protocol head to make quicker, more informed decisions about IP address states when interacting with its protocol clients. It also allows the protocol head to anticipate IP movement so that it can provide improved availability and fewer disruptions for its protocol clients, improving the continuous availability experience.
