Abstract: In one aspect, a method of sending traffic in a telecommunications network is provided. The telecommunications network includes a first branch network, a second branch network, intermediate system, and a head office network having a server. The first and second branch networks communicatively connected to the head network via the intermediate system. Traffic for the second branch network is received at a first branch network. The traffic at the first branch network is modified such that the intermediate network forwards the traffic to the head network. The intermediate network recognises that the traffic is for the second branch network. The traffic is received at the head network, and the traffic is modified at the head network such that the intermediate network forwards the traffic to the second branch network.

Abstract: In order to transmit data packets between a wirelessly connectable communications device and a communications partner, particularly during a handover process, the invention provides that when a first wireless transmission path is available, an availability of at least one additional wireless transmission path is detected. Based on the detection, a specific assignment schema, via which at least one portion of the data packets is assigned to each of the transmission paths, is selected according to specific transmission requirements and/or to a transmission protocol to be used for transmitting the data packets. An address specification specific to the transmission path is then assigned to a respective data packet that is assigned to a transmission path. By using the assigned address specifications, the data packets are transmitted via the different transmission paths between the communications device and the communications partner according to the selected assignment schema.

Abstract: A method for the user-based processing of electronic messages comprising file attachments is provided. According to the method, a file attachment of an electronic message is replaced by a memory location link to a selected memory location in a user file system and the file attachment of the electronic message is saved in the selected memory location of the user file system. This permits the memory capacity that is required for storing data attachments to be significantly reduced in a user-friendly system.

Abstract: In the context of making a cell-loss-sensitive connection between an originating subscriber device and a destination subscriber device via an ATM coupling field, a connection is set up only if the sum of the connection bandwidths of cell-loss-sensitive connections, executed via a logical point-to-point connection connecting the destination subscriber device with the ATM coupling field and in the process of being made, is less than or equal to a predeterminable limit value. All other connections are set up without checking.

Abstract: In a first step a maximum waiting time corresponding to different worst cases at the node is computed, whereby the different worst case scenarios are dependent on the constellation of arrivals of packets of a number of active voice connections. In a next step a delay threshold for the maximum waiting time and a probability are defined. In a last step the bandwidth of the network node's output line is dimensioned in such a manner, that the delay threshold is not exceeded except in cases which occur as rare as the defined probability. Using this dimensioning concept, no packet has to wait more than the predefined delay threshold in most cases. Only in a few “unfortunate” cases, the threshold is exceeded and that happens with the defined probability and that is when more packets are present in the buffer of a network node than considered while dimensioning.

Abstract: A method for implementation of a firewall application is disclosed, whereby, in one step (S1, S2, S3) of the initiation of a connection from the first to the second terminal (1, 2), authentication data for authentication of the first terminal is transmitted and, after successful authentication a selected address is communicated to the firewall device (9). An arrangement for carrying out the method is given.

Abstract: In the method, starting from a central management component as the basis it is determined in a first step whether a network component is a management-capable network component. If this is the case, the management-capable network component is classified on the basis of services provided in the past by the management-capable network component. A classification is made here into the classes host, router and switch.

Abstract: In the framework of a conversion of a feature control signaling, an item of feature control information (LO1, LO2, LO3) is extracted from a protocol-specific feature control message (SETUP) of a communications network (SCN) and is transmitted to a feature-neutral coordination module (KM). Said coordination module (KM) then relays the item of feature control information (LO1, LO2, LO3) to a feature-specific conversion module (UM1, . . . ,UMN), which converts the relayed item of feature control information (LO1, LO2, LO3) into an item of feature control information (ULO1, ULO2) that is specific to another of the communications networks (LAN). The converted item of feature control information (ULO1, ULO2) is subsequently inserted into another protocol-specific feature control message (SETUP) and is transmitted therewith into the other communications network (LAN).
