Abstract:
The present disclosure relates to a method for traffic engineering in a communications network. In one example method, a controller determines at least one sampling node in a flexible node and a temporal frequency for traffic sampling. The controller instruct the at least one sampling node to perform traffic sampling at the temporal frequency. The controller receives sampled traffic data of all sampling nodes obtained during each sampling. The controller determines, according to the sampled traffic data obtained during each sampling and information about total traffic of a link whose link utilization is greater than a first preset value or less than a second preset value in the communications network, parameter information for traffic engineering. The controller performs traffic engineering control according to the parameter information.

The data transmission system includes: a data interface device configured to receive a data stream from a server, and generate a forwarding request according to the data stream, where the forwarding request includes a destination address of the data stream; a controller device configured to generate a forwarding configuration signal according to the forwarding request; and an all-optical switching matrix configured to set an optical switching path between two data interface devices according to the forwarding configuration signal, so as to forward the data stream to a server specified by the destination address, where the two data interface devices are data interface devices connected to the source server of the data stream and the server specified by the destination address.
Abstract:
A transit device receives a target token request sent by a data transmit end, and sends the target token request to a data receive end. The data receive end may determine, based on the target token request, a target token packet corresponding to the target token request, and then send the target token packet to the transit device based on a priority identifier. The transit device determines a sending rate of the token packet based on a link bandwidth of the current device, a preset packet length of a token packet, and a preset packet length of the data packet, and sends the target token packet to the data transmit end based on the priority identifier and the sending rate of the token packet. The transit device may send the target data packet to the data receive end.
