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： 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.
