Abstract
The invention includes a method and apparatus for providing load balancing of control traffic received by a mobility home agent implemented using multiple control elements. A method includes receiving, from a node, a control message intended for the network element, performing a load-balancing operation to select one of the control elements to handle the control message, and propagating the control message toward the selected one of the control elements. The load-balancing operation is performed using at least two load-balancing metrics comprising a first metric and a second metric. The load-balancing operation is performed in a manner for maintaining a context between the node from which the control message is received and the selected one of the control elements, such that subsequent control messages received from the node are propagated to the selected one of the control elements.
