摘要:
It is presented a method for a network traffic scheduler to select a winning input node using a node hierarchy comprising: a plurality of input nodes; an output node; a plurality of intermediate nodes, wherein a subset of the intermediate nodes comprises intermediate nodes being connected to at least one lower level node and one higher level node. The method comprises the steps of: selecting a lower level node as a winning node; obtaining a set of input parameters, the input parameters comprising input data being associated with the winning node; obtaining output parameters by finding a matching row in a lookup table using the input parameters as a key; and providing the output parameters to the higher level node, wherein, when the higher level node is an intermediate node, at least a subset of the output parameters are used as input parameters for the higher level node. By using lookup tables, the relationship between input parameters and output parameters is much more flexible. This allows for implementation of all currently known useful functions, but also allows definition of completely new functions in the future.

摘要:
Various technologies pertaining to scheduling network traffic in a network are described. A request to transfer data from a first computing device to a second computing device includes data that identifies a volume of the data to be transferred and a deadline, where the data is to be transferred prior to the deadline. A long-term schedule is computed based upon the request, wherein the long-term schedule defines flow of traffic through the network over a relatively long time horizon. A short-term schedule is computed based upon the long-term schedule, where devices in the network are configured based upon the short-term schedule.

The invention relates to a method for transmitting messages in a computer network and to a computer network of this kind. The computer network comprises computation nodes (101-105), which computation nodes (101-105) are connected to one another via at least one star coupler (201) and/or at least one multi-hop network (1000), each computation node (101-105) being connected to the at least one star coupler (201) and/or to the at least one multi-hop network (1000) via at least one communication line (110), and the computation nodes (101-105) exchanging Ethernet messages with one another and with the at least one star coupler (201) and/or the at least one multi-hop network (1000). Provision is made for a set of two or more components each to be directly connected to one another by two or more communication lines (110, 111), each component in the set being either a computation node (101-105) or a star coupler (201), and sending components in the set of components sending at least some of the Ethernet messages that are to be sent to at least two of the two or more communication lines (110, 111), and receiving components in the set of components accepting and/or forwarding at least some of the Ethernet messages that are received via the two or more communication lines (110, 111) only if at least two identical messages are received via at least two different communication lines.

In a modular signal mirroring system each point-to-point RF transceiver end has a controller module (500) coupled to one or more I/O modules (502). The I/O modules (502) have various input and output circuits. A signal received a the near end is reconstructed at the fa end after being transmitted in an RF packet. The reconstructed signal may be the same as the input signal, inverted from the input signal or level-shifted from the input signal. It is representative of the input signal following the input signal's state after a time-quantization latency.

A method and an apparatus for controlling data transmission can reduce occurrence of collisions between stations. The method includes: determining at least one first station; and sending first indication information to the first station, where the first indication information is used for indicating at least one first backoff duration, so that the first station performs a data transmission operation by using the first backoff duration, and the first backoff duration used by the first station to perform a data transmission operation is less than a second backoff duration used by a second station to perform a data transmission operation, or the first backoff duration used by the first station to perform a data transmission operation is greater than the second backoff duration used by the second station to perform a data transmission operation. Shortening backoff durations of some stations can ensure that these stations send data first, and extending backoff durations of some stations can ensure that the other stations send data first. Therefore, occurrence of collisions between the stations can be reduced.
