| 摘要 |
The present invention relates to the transmittal of data packets of a data packet flow in a data center network 100 by means of an external control by a control unit 14, which collects, by means of Link Layer Discovery (LLDP) protocol messages, monitoring data informing about the utilisation and status 16a of paths and links therein and CPU consumption and memory consumption 16b relating to virtual machine instances 12 of a service. Based on that information, the control unit 14 determines indicators 20, corresponding to weights or priorities, which are then sent back to the data center network 100, for the switching units 10 being able to determine a respective number of data packets which are to be transmitted along a specific path, wherein these numbers differ for at least two paths. Paths having a high load or paths having specific links of which the load is rather high, or paths wherein computer processing units or memory are extensively used, can be caused to transmit less data packets than in the prior art. |
