Abstract
Methods and arrangements for supporting a forwarding process in routers when routing data packets through a packet-switched network, by employing hierarchical parameters in which the hops of a predetermined transmission path between a sender and a receiver are encoded. A name server generates and distributes router-associated keys to routers in the network which keys are used for computing the hierarchical parameters.
