1. A method for communicating network configuration changes to protocol heads within a cluster of nodes comprising:

  • initiating by a protocol head among a set of protocol heads within a node among the cluster of nodes a network configuration monitoring agent;

    receiving by the network configuration monitoring agent a current network configuration state;

    storing the current network configuration state in an in-memory cache associated with the protocol head within the node;

    registering by the network configuration monitoring agent for a set of event notifications associated with a network configuration file for the cluster of nodes, wherein the set of event notifications includes a will move event;

    in response to receiving a will move event notification indicating that an internet protocol (“

    IP”

    ) address will move from a first node among the cluster of nodes to a second node among the cluster of nodes, notifying the protocol head of the will move event notification; and

    in response to being notified of the will move event notification, at least one of modifying a set of IP addresses given to new client requests by the protocol head and delaying responses to new client requests associated with the IP address by the protocol head, prior to the IP address moving from the first node to the second node.
