Abstract: A method for transferring Multiprotocol Label Switching (MPLS) packets in connectionless networks, the MPLS packets passing a number of inner MPLS switching nodes on a transmission path between a sender and a destination as well as at least two MPLS edge routers, each MPLS edge router being a transition between a core network and a connection network, include: producing an address stack or label stack for an MPLS packet to be sent. The address stack or label stack includes address information on the inner switching nodes to be passed on its transmission path and address information for the at least two edge routers to be passed on its transmission path.

Abstract: A method and system are provided for determining label-switched routes between a source router and a target router of an independent communications subnet, over which information packets having a predetermined IP target address are to be transmitted. An independent communications subnet suitable for implementing the method as well as to routers used therein also is provided. In an embodiment, the label-distributing multi-protocol, hitherto only used in IP backbone networks, is coupled with an internal subnet route protocol that is used in independent communications subnets so as to be able to design a more efficient and faster routing of information packets over different route topologies in an independent communications.

Abstract: The invention relates to a method for determining label-switched routes between a source router and a target router (11, 14; 21, 24) of an independent communications subnet (10; 20), over which information packets having a predetermined IP target address are to be transmitted. The present invention furthermore relates to an independent communications subnet suitable for implementing the method as well as to routers used therein. The basic idea of the present invention is to couple the label-distributing multi-protocol, hitherto only used in IP backbone networks, with an internal subnet route protocol that is used in independent communications subnets so as to be able to design the routing of information packets over different route topologies in an independent communications subnet to be more efficient and faster.
