Abstract: The invention relates to a method for transmitting information between two entities via a network. Said method comprises a first protocol that uses network paths, which are identified by labels and whose target entity and source entity are un-equivocally defined, for transmitting information between the entities and comprises a second transport protocol, which is built on the first protocol. According to the invention, the transport protocol guarantees the receipt of information by means of a confirmation. The method also comprises a first initialising step, in which 1 to n labels of network paths, which permit an information exchange between the entities, are exchanged via a first network path and a second information exchange step, in which the information is exchanged via the 1 to n network paths. The first protocol is preferably MPLS, each FEC standing for a unique target and source entity. The second protocol is preferably SCTP, the IP addresses being replaced by the labels from the network paths.

Abstract: Only the routers of mobile anchor points rather than all of the routers in a network, as was previously the case, have to modify the number of the mobile anchor points. The hops are calculated from the hop limit and the respective hop numbers in the respective mobile node.

Abstract: The invention relates to a method and an arrangement for transmitting a data packet from a first network unit to a second network unit in a data network. A first connection information unit is transmitted to the first network unit. A connection is established between the first network unit and the second network unit by means of said first connection information unit. The first network unit assigns a second connection information unit to the data packet. The data packet is subsequently transmitted to the second network unit by means of the first network unit using the second connection information unit.

Abstract: Systems, a method and a program product transmit data in which a transmission price is transmitted for the data which are to be transmitted.
