Dynamic adaptive adjustment method of virtual network resources based on nonlinear dimensionality reduction

Abstract

The invention relates to a dynamic adaptive adjustment method of virtual network resources based on nonlinear dimensionality reduction. The method comprises steps: data of an underlying physical network are acquired, and data of nodes or links, relative to real-time remaining resources in multiple adjacent time points, in the underlying physical network are obtained; dimensionality reduction processing is carried out on the acquired data, and a two-dimensional relationship distribution chart of the nodes or the links in the underlying physical network is obtained; the nodes or the links in the underlying physical network are clustered according to the two-dimensional relationship distribution chart; according to the clustering result, mapping is carried out again on the virtual network in the next period of time, and in the re-mapping process, a node cluster or a link cluster with a low utilization rate in the underlying physical network is preferably selected to carry out virtual resource mapping; and after running for certain period of time, the above steps are carried out again until the process of allocating the virtual resources is over. With the method, the execution efficiency of mapping algorithm can be effectively improved, the resource utilization rate is improved, and load balancing can be realized.

Description

technical field [0001] The invention relates to the field of network transmission, in particular to a method for dynamic self-adaptive adjustment of virtual network resources based on nonlinear dimensionality reduction. Background technique [0002] The Internet has achieved tremendous development in the past 20 years, but it is also facing a series of problems, including scalability, security, etc., and network virtualization is considered to solve the current Internet security, mobility, scalability, etc. important technical means of the problem. In the cloud computing and data center network environment, network virtualization can help the network to achieve efficient resource utilization, dynamic scheduling, and effective isolation. Network virtualization selectively allocates and schedules resources through abstraction, allocation, and isolation mechanisms, so as to realize simultaneous operation of multiple virtual networks on the same physical network, thereby improv...
