摘要： The network (PN1 ) comprises a plurality of private sub-networks (C1,C2,CI,CII), which can be coupled to each other by means of a public network (150). The clusters comprise a gateway (GW1,GW2,GWI,GWII) to the external network and at least one node. The nodes have local addresses, which are used for transmitting a packet to other nodes in the same cluster. The local addresses are unique within the same cluster, but possibly overlapping with the local addresses of nodes outside the cluster. Furthermore, the nodes have overlay addresses, which are used by the nodes in the other clusters. The network comprises overlay network routing means, which store the local addresses and the overlay addresses of all the nodes in the network and a mapping between them. The gateway of the cluster forwards a packet having an overlay address originating from a node in its cluster to the overlay network routing means. The overlay network routing means translate the overlay address in the packet to the local address of the destination node and forward the packet to the gateway of the cluster to which the destination node having the overlay address belongs. The gateway of the cluster of the destination node routes the packet to the destination node based on the local address thereof.
