Abstract: A message flow shaping approach for a network element capable of message routing is presented. The network element is configured to receive one or more logical ingress message flows and to output one or more logical egress message flows, wherein a flow priority level is allocated to each ingress and egress message flow. A method implementation of the technique presented herein comprises the step of the determining a message flow congestion state per flow priority level at an egress side of the network element. The method further comprises the step of triggering a message flow shaping operation. The message flow shaping operation is triggered per flow priority level at an ingress side of the network element dependent on the congestion state determined for at least one associated flow priority level at the egress side.

Abstract: A node (111-114) in a multi-path network (100) sends a first message to a first egress node (111-114, 121), the first message being directed to at least one target node (121). After said sending, the node (111-114) receives an answer message. Based on the answer message, a value indicative of the identity of an originator node (111-114, 121) of the answer message is added to a routing record of a second message. The second message is directed to the at least one target node (121). The second routing message is sent to a second egress node (111-114, 121).

Abstract: A technique for discovering topological information in connection with an application layer messaging protocol that uses hop-by-hop routing is disclosed. An exemplary network element provided by the present disclosure comprises a memory in which a routing table is stored. The routing table includes one or more table entries, with each table entry associating a hop supported by the network element with a message destination potentially reachable via that hop. The network element further comprises at least one processor configured to determine topological information about a local logical topography of the network element and to trigger transmission of the topological information to the hops defined in the routing table. Responsive to receipt of the topological information, the hops may modify their local routing table so as to arrive at improved routing decisions.

Abstract: The invention generally relates to a method, by a proxy agent, for establishing a communication session between a first and a second communicating entity over the proxy agent in a communication network. This session comprises a plurality of messages which are exchanged between the first communicating entity and the proxy agent and the proxy agent and the second communicating entity. The proxy agent inserts session information to a first message received by the first or the second communicating entity. The proxy agent then sends the first message to the first or the second communicating entity. The proxy agent then receives a second message by the first or the second communicating entity. This second message contains the session information which is then analysed by the proxy agent. Based on this session information the proxy agent sends a third message to the first or the second communicating entity.

Abstract: A switching device (PLMN-SW) in a mobile radio communication system (PLMN) which supports a GPRS-network allows to connect a terminal station (GPRS-MS) of the mobile radio communication network (PLMN) with one of a plurality of packet data communication networks (PDN1, PDN2, IN). The selection of the packet data communication network (PDN1, PDN2, IN) is based on the transmission of a specific network indication parameter (NIP) from the terminal station (GPRS-MS) of the mobile radio communication network (PLMN). The network indication parameter (NIP) is transmitted to a serving (GPRS) support node (SGSN) as a special parameter in a PDP context activation procedure. Thus, a large number of internet service providers (ISP1, ISP2, ISP3) can be connected to a GPRS-network.

Abstract: A mobile switching center (MSC) not equipped with the necessary hardware/software devices or modules communicates with a Shared Interworking Function node to provide an Interworking function (IWF) service to a particular mobile station. Control data associated with the requested IWF service are transported from the serving MSC to the SIWF node using basic and supplementary Integrated Service Digital Network User Part (ISUP) signals. Such control data are encapsulated into optional parameters within the transmitted ISUP signals and transparently transported from the serving MSC to the SIWF telecommunications node.
