Problems solved by technology

At present, OpenStack is deployed on physical servers. The access bandwidth of OpenStack-based data centers is limited, and the unreasonable allocation of resources will cause virtual machines on physical nodes to compete for resources when accessing the external network or other virtual machines. The cloud platform provides The basic application services cannot reasonably utilize the allocated network resources on demand, resulting in a waste of resources

Embodiment Construction

[0133] Below in conjunction with embodiment, the present invention is further described, but does not constitute any restriction to the present invention, any limited number of modifications done in the scope of claims of the present invention is still within the scope of claims of the present invention.

[0134] A kind of OpenStack virtual machine bandwidth allocation method based on application service of the present embodiment, described method comprises the following steps:

[0135] Step 1. Develop network QoS indicators for OpenStack cloud platform applications. Network QoS refers to the ability to ensure certain network requirements to meet the service level agreement (SLA) between application providers and end users. Network requirements include bandwidth, delay, Jitter and reliability.

[0136] The formulation process is as follows:

[0137] S1-1. Investigate the service network QoS demand indicators of different companies. Services are divided into voice services, v...

Abstract

The invention discloses a virtual machine bandwidth allocation method of OpenStack based on application service. The virtual machine bandwidth allocation method comprises the following steps: 1, specifying a network QoS index of an OpenStack cloud platform application; step 2, determining an ARIMA prediction model; 3, calculating an effective bandwidth based on the QoS of the application accordingto the statistical characteristics of the application flow; 4, predicting the network load state of the virtual machine in the next period according to the effective bandwidth; and 5, allocating thebandwidth by the network load state of the virtual machine according to different allocation strategies. The virtual machine dynamic bandwidth allocation method overcomes the defect that a static bandwidth allocation method is low in resource utilization rate, overcomes the defect that a traditional bandwidth allocation method cannot guarantee QoS of an application network, reasonably and effectively utilizes OpenStack cloud platform bandwidth resources, increases the bandwidth resource utilization rate, and meanwhile guarantees QoS of virtual machine application.

Description

technical field [0001] The invention relates to the field of cloud computing, in particular to an OpenStack virtual machine bandwidth allocation method based on application services. Background technique [0002] Cloud computing is a new delivery model and business model for computing resources, network resources, and storage resources. It improves services through dynamically scalable virtualized resources. OpenStack, as an open source cloud platform project that is still active at present, has attracted extensive attention from the business community and academia with its efficient community development and flexible deployment model. [0003] Network resources are one of the important resources of the cloud data center, and the network resources connected to the cloud data center are limited. How to allocate network resources reasonably is a problem that the cloud data center needs to solve. At present, OpenStack is deployed on physical servers. The access bandwidth of Op...
