ABSTRACT:
A method for handling dynamic state information used for handling data packets, which arrive at a network element node of a network element cluster, said network element cluster having at least two nodes and each node handling separate sets of data packets. In a node there is maintained206a first, node-specific data structure comprising entries representing state information needed for handling sets of data packets handled in said node. In said node there is also maintained208a second, common data structure comprising at least entries representing state information needed for handling sets of data packets handled in one other node of said network element cluster. The contents of said common data structure effectively differs from the contents of said node-specific data structure. Data packets are distributed202, 204to nodes of the cluster by means of distribution identifiers allocated200to nodes. Advantageously, information related to the distribution identifiers is included212in the entries of the data structures in order to identify to which node a set of data packets represented by a given entry belongs to at a given moment.
