Abstract

The invention discloses a virtual network mapping method based on energy consumption perception of an enterprise network, which comprises the following steps: constructing a network model and an energy consumption model, establishing a new network model and a new energy consumption model, and performing node mapping and link mapping on an enterprise-level virtual network mapping problem; and adopting a two-stage energy consumption perception mapping algorithm, an energy consumption perception model including node energy consumption and link energy consumption is provided for an enterprise-level network, serving the energy consumption model as a target function of virtual network mapping, and therefore, the high resource utilization rate is achieved, the mapping time of virtual requests isshortened, and the mapping efficiency is improved. The energy consumption of virtual network mapping in an enterprise network is effectively reduced. The network model of the enterprise network is constructed, the new energy consumption model is constructed, and the virtual network request is preferentially mapped to the physical network with the minimum energy consumption and meeting the requirement, so that the running time is shortened, the energy consumption of virtual network mapping is obviously reduced, and the success rate of virtual network mapping is relatively high.

Description

technical field [0001] The invention belongs to the technical field of virtual network mapping methods, and in particular relates to a virtual network mapping method based on energy consumption perception of an enterprise network. Background technique [0002] After a long period of development, the Internet has brought great convenience to people's lives. In recent years, the Internet has developed at a great speed. Now many applications and network technologies are running on the Internet, and the network scale has increased. directly lead to an increase in energy consumption. [0003] The increase in network scale will also lead to network rigidity, so in order to solve the problem of Internet rigidity and the increase of network energy consumption, network virtualization technology appears, mainly to separate service providers and infrastructure providers, mainly to separate different Virtual networks coexist on the same physical network to meet the special requirements...

Problems solved by technology

[0005] In order to solve the problem of efficiently allocating virtual networks and controlling the underlying physical network in network virtualization, virtual network mapping technology has emerged. As the core problem, virtual network mapping technology is to map virtual network requests with node constraints and link constraints to On the physical network, the virtual network mapping problem is an NP-Hard problem. How to efficiently map the virtual network requests with constraints on the physical network is a major problem. At present, many algorithms are designed to reduce the virtual network mapping. Cost is the goal, mainly to improve the underlying network mapping benefits, and few studies consider energy consumption in the virtual network mapping problem

Although these energy-saving algorithms can be well applied in the Internet environment, in the enterprise network, since there are no non-working nodes in the underlying physical network, the energy consumption optimization problem is not to minimize the number of working nodes, so the current proposed Most energy-saving virtual network mapping methods cannot be well applied in energy management of enterprise networks
