Grey-prediction-based adaptive dynamic resource allocation method for virtual network

Abstract

The invention discloses a novel virtual network-oriented resource allocation method, and aims to solve the problems that an allocation error cannot be rapidly reduced, the rationality of global virtual resource allocation is not taken into account, a resource utilization rate and a resource allocation process are not associated so as not to effectively adjust the resource utilization rate, and the like of the conventional resource allocation method for a core virtual network. According to the method, the concept of resource use prediction is disclosed for the first time, the resource using amount of each virtual node is predicted by a grey model, virtual resources are allocated according to an adaptive feedback algorithm, and detection and reallocation are performed to ensure resource allocation rationality to finish the resource allocation process of the virtual network. By the method, the requirements of resource allocation of a plurality of virtual planes can be met, an error between a dynamic resource allocation value and an actual resource use value is rapidly reduced, the resource utilization rate of each virtual plane node can be controlled respectively, and the rationality and effectiveness of resource allocation results are ensured.

Description

Technical field: [0001] The invention mainly aims at the resource allocation technology under the virtual network environment, and in particular provides a technical solution for a forecast-based self-adaptive dynamic resource allocation applied to the virtual network. Background technique: [0002] The Internet has only considered "best effort" data services at the beginning, and now the Internet has all-encompassing applications, and new services emerge in an endless stream. The common VoIP services, IPTV services, 3G services, etc. in daily life are all in IP. based on technology. However, because the Internet is served by a variety of service providers, it is very difficult to adopt a new architecture or make some modifications on the existing architecture, which makes the existing Internet technology not conducive to supporting mobility and affecting the core The scalability of routing reduces the effectiveness of existing security methods and hinders the development o...

Problems solved by technology

[0010] However, the above-mentioned fault detection methods have the following disadvantages: a. Recalculation after a large amount of monitoring or interaction of a large amount of information is required, and each dynamic resource allocation takes too long, which cannot satisfy fast resource allocation; b. Does not consider how to Reduce the error between the resource allocation value and the actual resource usage value, so that the allocation result is more reasonable and accurate; c. It does not consider the change process of the resource utilization rate on the virtual node, so it does not consider how to improve the resource utilization rate of the virtual network and control resource utilization d. Without considering the failure of the initial initial allocation, how to adjust to quickly complete the readjustment of resource allocation, so as to meet the network requirements
