Problems solved by technology

This limitation makes it impossible for cloud providers to guarantee a minimum bandwidth to a tenant while targeting network scale and high utilization
For example, when a provider guarantees a minimum bandwidth for specific traffic by reserving bandwidth, the overall network utilization decreases due to the unused reserved bandwidth

Abstract

The invention relates to the technical field of cloud calculation, in particular to a virtual machine and network bandwidth joint allocation method based on multi-QoS grouping, which comprises the following steps: constructing a task model based on multi-QoS grouping; sorting all the application program requests according to the QoS levels so as to form request queues of the application programs;sequentially taking out the application programs from the request queue, and allocating virtual machines to the application programs by applying a virtual machine allocation strategy according to resource requirements of the application programs; and performing network bandwidth allocation by using a network bandwidth dynamic allocation strategy according to the link and flow information allocatedby the virtual machine. According to the method, the calculation resource parameters and the QoS parameters are comprehensively considered, the QoS requests of the application programs can be accurately graded. The bandwidth requirements of the application programs with high QoS grades can be well guaranteed by adopting a combined virtual machine allocation strategy and a dynamic bandwidth allocation strategy. The efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of cloud computing, in particular to a multi-QoS group-based virtual machine and network bandwidth joint allocation method. Background technique [0002] Most of the current Internet applications utilize cloud computing infrastructure to provide elastic and cost-effective services. Cloud providers provide tenants with computing, storage, and network resources to meet applications with different needs. These applications require different amounts of resources with different priorities. Large-scale scientific applications, computing-intensive applications require more computing and storage capabilities than network resources, and network-intensive applications require more network bandwidth than computing capabilities. Therefore, the cloud provider should efficiently allocate and schedule resources in the data center to meet various needs, and the cloud provider also needs to guarantee the customer's service...
