Data center flow scheduling method based on quality of service

Abstract

The invention relates to the technical field of networks, and in particular relates to a data center flow scheduling method based on service of quality. The method comprises the steps as follows: whenreceiving a data flow sent by a host, the switch of an access layer judges whether to be directly connected with the target host according to a target address, and if yes, data is forwarded to the target host to complete scheduling; whether a transmission rate of the data flow is less than a preset threshold is judged, if yes, the switch adopts an equivalent multi-path scheduling mechanism to complete scheduling; a controller uses the shortest path algorithm for the data flow to find the shortest path set between a data source and the target host; and an optimal ant colony algorithm is used for acquiring the optimal path from the shortest path set, and the scheduling of the data flow is completed via the optimal path. According to the method provided by the invention, aiming at the different requirements of the different types of services in a data center on network performance, the different scheduling methods are used, so that the quality of service can be effectively ensured, and meanwhile the low computing complexity of the method is ensured.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a data center flow scheduling method based on quality of service. Background technique [0002] The data center is the center of data transmission, computing and storage. It concentrates various hardware and software resources and key business systems, such as Web services, web search, online shopping, online games, and MapReduce large-scale cluster computing. In recent years, with the virtual With the wide application of modernization technology and the development of emerging application modes such as cloud computing, the data center network is gradually developing in the direction of scale, intelligence, virtualization, etc., and congestion problems will inevitably occur during the operation process, causing this problem The main reason is that the uneven distribution of network resources in the network makes the traffic load of each link unbalanced. Therefore, it is very nec...

AI Technical Summary

Problems solved by technology

[0004] The existing data center traffic scheduling scheme based on quality of service mainly avoids network congestion and indirectly guarantees service quality by improving load balance, and cannot perform targeted scheduling according to different requirements of different business flows on network performance, so it cannot Ensure the service quality of different businesses to improve user experience
