Abstract

The invention discloses a cloud storage network multicast flow scheduling method based on service priority distinction, which includes: S1 using software-defined network technology to monitor and obtain network status information in real time; S2, after the multicast service flow is based on the requirements of network performance. Priority distinction; S3 decomposes the multicast path selection task into multiple unicast path selection tasks when selecting a multicast path for a multicast service flow; S4 distinguishes between the different priority multicast service flows and the current one. Network state, find an optimal unicast path set based on the ideal solution for each decomposed unicast path selection task; S5 determines the multicast distribution node through the maximum common subpath between each path set to construct a multicast transmission path. While ensuring the load balance of the data center, the present invention reduces redundant traffic, reduces the transmission time of high-priority service streams, and improves user experience.

Description

technical field [0001] The invention relates to the technical field of cloud storage, in particular to a cloud storage network multicast flow scheduling method based on business priority distinction. Background technique [0002] Cloud storage is a new concept extended and developed on the concept of cloud computing. It is an emerging network storage technology. A large number of different types of storage devices work together through application software to jointly provide data storage and business access systems. The cloud storage system uses data center network technology to integrate storage devices. Most of the existing data center network flow scheduling methods are aimed at the data center network environment where the traffic pattern conforms to the long-tail distribution, that is, 90% of the data flows are small flows, but the remaining 10% of the large flows occupy 90% of the network bandwidth. In the context of this data center network environment, some researc...
