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： The invention relates to a method for improving the quality of data transmission in a packet-based communication network comprising a plurality of network nodes (K). Each of the network nodes (K) has a number of ports (P) with which at least one queue (Q) is associated respectively, and by means of which ports a communication connection (KV) to another network node (K) can be produced. According to the method of the invention, at least the queues (Q) of those ports which are arranged, in the network nodes (K), along, respective communication paths that are formed in the communication network, are monitored for their queue length. In addition, a degree of overload of the affected port(s) (P) is determined from the queue length, and on the basis of the degree of overload of the communication path(s) (PF1, PF2, PF3) running across the affected overloaded port (P), a runtime delay (delay) and/or a delay variation (jitter) in the data transmission can be inferred. Finally, the overload amount rises above a predetermined threshold value for at least one of the communication paths (PF1, PF2, PF3) running across an overloaded port (P). An alternative communication path (PF2′) is configured, the overloaded ports (P) thus being bypassed.

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.

摘要： The invention relates to a method for operating a communication network (101), in particular an Ethernet network. 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.
