Abstract: Method, communication network and datacenter for data traffic management in a communication network. The invention provides a method for data traffic management in a communication network. The method first includes setting up a first communication path for a first data communication and transmitting data from a source of the first data communication to a destination of the first data communication. Then, features of a saturation tree representing a congestion of data transmission in the first data communication are monitored and a data rate of the first data communication along the first communication path is adapted based on the monitored features. The present invention further provides a datacenter and a communication network.

Abstract: A network device including at least one rate-limited-queue and multiple timer modules, the network device being operable to receive and/or transmit data flows from and/or to a communication network. Each data flow includes multiple data packets. The network device being further operable to limit the predetermined transmission rate of the respective data flow dependent on whether a data congestion in the communication network has been indicated, in such a way, that in case of an indicated congested communication network a respective timer module is associated to each of the data flows and/or each group of data flows, whereas the data packets of the respective data flows and/or group of data flows are buffered in the rate-limited-queue. Each data packet in the rate-limited-queue is transmitted with a limited transmission rate predetermined by the respectively associated timer module when the data packet is at the head of the rate-limited-queue.

Abstract: The method for scheduling interconnections in an interconnecting fabric comprises the following steps. In a determined time slot input selectors generate requests using a request pointer set, which is related to the determined time slot. Then, the requests are transmitted to output selectors, and the output selectors issue grants using a grant pointer set, which is also related to the determined time slot. In a further step the grants are transmitted to the input selectors, and the input selectors update the request pointer set. These steps are repeated, wherein for a further time slot a further request and grant pointer set are used, which are related to the further time slot.
