    摘要： 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.

    摘要： 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.

    摘要： The present invention provides for congestion and flow control for a data transmission between computers in a network (e.g., a lossless network) by repeatedly setting a transmission rate for the data transmission at predetermined time intervals. Under the present invention, a ratio of a current occupancy to a maximum occupancy of a queue used for the data transmission is provided (e.g., the ratio can be calculated under the present invention, or obtained as input from an external source). The queue can be that of the receiving computer or of any component (e.g., a switch) that resides in the path of the data transmission. In any event, once the ratio is known, the present invention will set the transmission rate for the data transmission based on a comparison of the ratio to at least one threshold.

    摘要： IEEE 802.1Q and Enhanced Transmission Selection provide only eight different traffic classes that may be used to control bandwidth in a particular physical connection (or link). Instead of relying only on these eight traffic classes to manage bandwidth, the embodiments discussed herein disclose using an Enhanced Transmission Selection scheduler that permits a network device to set the bandwidth for an individual virtual LAN. Allocating bandwidth in a port based on a virtual LAN ID permits a network device to allocate bandwidth to, e.g., millions of unique virtual LANs. Thus, this technique may increase the granular control of the network fabric and its performance.

    摘要： A method is described to operate a crossbar switch comprising a crossbar fabric with N sending and M receiving ports, with port cards connected to at least one sending and/or receiving port each of the crossbar fabric, said crossbar switch further comprising a control unit connected with the port cards via discrete control channel links, wherein C ports are clustered on a single receiving port card so that such a receiving port card in a single time-step can receive up to C data cells from C sending port cards simultaneously. According to said method the control channel links are used to relay up to C acknowledgements between at least one receiving port card and at least one sending port card.

    摘要： A system and method for generating a computation graph corresponding to a communication graph and a network topology graph for a communication network interconnected using switch-elements is provided. Computation is placed in switch-elements of the computation graph. The method includes determining one or more operator-switch-elements for a computation level of the computation graph corresponding to one or more preceding-computation-level operand elements using span vector representation of the network topology graph. The method further includes selecting a last-computation-level operator-switch-element corresponding to a root-compute-node. The method allows computation to be placed inside a network to meet resource availability constraints.
