Abstract
In a network element cluster having a plurality of nodes, distribution decisions are determined on the basis of certain field(s) of data packets according to predetermined criteria, and data packets are distributed to nodes of the network element cluster according to the distribution decisions. Data packets are processed by said nodes of the network element cluster, and the processing involves selecting at least partly arbitrary value(s) for at least one of the field(s) of at least one data packet. Such value(s) are selected for at least one of said certain field(s) of a third data packet, such that distribution decisions determined according to the predetermined criteria result in the same node in the cluster processing inbound and outbound packets of the same session ID.
