Embodiment Construction

[0036] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, and do not limit the protection scope of the present invention.

[0037] Through the observation of the network traffic pattern of the cloud data center, based on the scheduling guiding ideology of "overselling during idle hours and low insurance during busy hours", the embodiment provides a cloud network resource elastic scheduling system and method based on an integral algorithm. The computing mechanism builds the corresponding credits between VM bandwidth usage and virtual switch CPU consumption, reasonably allocates virtual switch network resources in the next stage, and ensures that the cloud network load on the entire data ce...

Abstract

The invention discloses a cloud network resource elastic scheduling system and method based on an integral algorithm. The system comprises a virtual switch module, a data acquisition module, an integral calculation module and a resource scheduling module. The virtual switch module serves as a core module for bearing a VM network function and is used for providing network service for the VM according to a CPU cycle proportion; the data acquisition module is used for collecting the actual CPU clock cycle number and the cycle proportion of the virtual switch consumed by each VM in each working time slice from the virtual switch module, and transmitting the actual CPU clock cycle number and the cycle proportion to the integral calculation module; the integral calculation module is used for updating the integral value of each VM according to the input actual CPU clock cycle number and the cycle proportion, and transmitting the updated integral value to the resource scheduling module; and the resource scheduling module is used for dynamically limiting the number of virtual switch CPU cycles consumed by each VM in the next working time slice and the cycle proportion according to the input integral value. According to the method, resource utilization of a plurality of VM networks tends to be at a reasonable level.

Description

technical field [0001] The invention belongs to the technical field of cloud data center networks, and in particular relates to a method and system for elastic scheduling of virtualized cloud network resources based on an integral algorithm. Background technique [0002] With the development of information technology, the trend of informatization of industrial enterprises is becoming more and more obvious, and the development of many industrial enterprises has gradually tended to intelligent operation, that is, enterprises go to the cloud. Enterprise cloud refers to the whole process of using Internet technology and cloud computing technology to connect social resources, share platforms and work content, and then carry out information management infrastructure construction, management methods, and business processes. As more and more enterprises migrate their services to the cloud, cloud service providers are under increasing operational pressure. On the one hand, the total...
