Abstract

The embodiment of the invention provides a data centre network flow dispatching method and system based on space and time combination. The method and the system are applied to a switch. The method comprises the steps of receiving a data packet and a target virtual local area network serial number value sent by a sending terminal, and determining a target output port for transmitting the data packet based on the target virtual local area network serial number value; determining the priority of the data packet, and caching the data packet to a target priority queue based on the priory of the data packet; judging whether the quantity of the data packets contained in the target priority queue exceeds a preset threshold value or not, and transmitting the data packet and other data packets cached in the target priority queue if the quantity does not exceed the preset threshold value; identifying a first identifier in the packet header of the data packet if the quantity exceeds the preset threshold value, and transmitting the data packet identified with the first identifier and other data packets cached in the target priority queue by employing the target priority queue. Through application of the embodiment, the quality of service of the high priority service can be ensured, and the finishing time of each priority task can be reduced.

Description

technical field [0001] The present invention relates to the field of network technology, in particular to a data center network flow scheduling method and system based on time-space integration. Background technique [0002] Currently, as the data center network becomes more and more complex, many new traffic scheduling mechanisms are applied to the data center network. However, these new traffic scheduling mechanisms can only improve the bandwidth utilization of the data center network, or can only prioritize the traffic transmission delay requirements of high-priority services, and cannot optimize these two aspects at the same time. [0003] Specifically, these new traffic scheduling mechanisms are divided into two categories, one is time-based traffic scheduling: the traffic is evenly distributed to redundant links, which aims to improve the bandwidth utilization of the data center network, thereby shortening the data The transmission time of traffic, but this type of tr...
