摘要： Managing end-to-end connections of a network includes estimating a load of network resources, and providing a quality of service status of the network. Quality of service parameters within the network are pre-calculated based on the load of the network resources and the quality of service status of the network, and the network resources are pre-allocated based on the pre-calculated quality of service parameters. Data packets are routed based on the pre-allocated network resources.

摘要： Systems and methods for transmitting data packets in a data network comprising a multiplicity of network nodes are provided. A routing topology associated with a respective network node is ascertained, wherein the routing topology describes paths for forwarding data packets between the respective network node and each other network node in the data network on the basis of links between adjacent network nodes. A piece of routing information with the identification of the respective routing topology is produced and is stored in the respective network node. A data packet transmitted from a source network node to a destination network node specifies the identification of the routing topology to be used for the transmission, wherein each network node that forwards the data packet uses the routing information stored on each network node with the identification of the routing topology for the data packet.

摘要： A method for clock synchronization in a communication network, in particular one based on packet switched data transmission, is provided. A first clock signal from a first network element is used as a reference signal for synchronization of a respective second clock signal from one or more second network elements. The first clock signal is transmitted at a transmission frequency intended exclusively for the clock signal or at a transmission frequency band intended exclusively for the first clock signal to the one or the more second network elements. The first clock signal is processed in the respective second network element in order to adjust the second clock signal such that the second clock signal matches the first clock signal.

Network devices (1) which are coupled to the network comprise a switch device (4), a first and a second control device (2, 3) which are coupled to the switch device (4), and the switch device (4) comprises for the first and the second control device (2, 3) a respective input port (10, 14) and emitter port (9, 13) for sending and receiving data via the communication network (6). Ring-shaped communication paths for data are provided so that redundant data can be transmitted in different directions and checked for consistency. An improved protection against failure and error analysis in the event of transmission errors are ensured by the ring-shaped structure using bidirectional communication paths. The invention further relates to a network arrangement (101) comprising several corresponding network devices (100, 200, 300) which operate according to the method.

摘要： An intermediate network in a ring topology includes a first marginal node and a second marginal node in a first network domain. The first and second marginal nodes are connected to one another by a first network connection within the first network domain. The intermediate network includes a third marginal node and a fourth marginal node, in a second network domain. The third marginal node and the fourth marginal node are connected to one another by a second network connection within the second network domain. A first virtual network connection connects the first and the third marginal nodes via an intermediate network. A second virtual network connection connects the second and the fourth marginal nodes via the intermediate network. The first network connection, the second network connection, the first virtual network connection, and the second virtual network connection have a ring topology on which a connection redundancy protocol is implemented.

摘要： Systems and methods are provided for operating a network arrangement including multiple network devices that are coupled to each other in a ring structure. Each network device includes a control device and a switch device with at least two ports for coupling to a communication path. During operation, at least two VLANs are simultaneously provided in the ring structure, and the sending of a data packet from the control device of a selected network device is performed via a port of the switch device in one of the two VLANs. In order to achieve this, the other port of the switch device of the selected network device is deactivated for the one VLAN. By using two VLANs, a redundant and reliable data transmission may be achieved. A destabilization of the VLANs in the network ring is prevented by the targeted deactivation of specific ports of the sending network device.
