Abstract
A method is provided including obtaining at a newly added flow mapper node of a plurality of flow mapper nodes, from a first flow locator node of a plurality of flow locator nodes, a flow owner lookup request for flow state information that includes identification of a particular flow locator that is to handle processing of a packet flow. The newly added flow mapper node determines whether it has stored flow state information. When the newly added flow mapper node does not have stored flow state information, the newly added flow mapper node identifies a particular flow mapper node of the plurality of flow mapper nodes which has stored flow state information for the particular packet flow and services the flow owner lookup request using flow state information stored by the particular flow mapper node.
