  • Looping MPLS paths at forwarding level for connectionless MPLS networks
    Patent number: 9344346
    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.
