Abstract

The invention discloses a method and device for virtual network mapping. The method comprises the steps of obtaining a network load change history curve that network load changes along with time; fitting the network load change history curve by utilizing a cosine trend function; obtaining an energy saving control factor according to a fitting curve and a network load critical value; when a network is in a high-load stage, adopting load balance virtual network mapping, and when the network enters a low-load stage, if a trigger condition of energy saving virtual network mapping is met, adopting the energy saving virtual network mapping, otherwise adopting the load balance virtual network mapping. According to the method and device for the virtual network mapping, self-adaptive energy saving virtual network mapping is achieved, a set of energy saving mapping scheme can be made according to a rule of history network service flow and the resource situation of a bottom layer network topology, and the mapping scheme can be adjusted in a self-adaptive mode with the combination of the situation of the current network service flow so that under the condition of ensuring service quality, the total network energy consumption can be reduced.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to the technical field of network virtualization, and relates to a method and device for realizing energy-saving virtual network mapping. Background technique [0002] Network virtualization is a technology that abstracts the underlying physical network infrastructure. Its core mechanism is that the service provider (Service Provider, SP) sends a virtual network request to the equipment provider (Infrastructure Provider, InP) according to the dynamically changing business needs of the user, and the equipment provider The use case maps the virtual network request to the underlying network, thereby providing users with flexible and diversified services while enhancing the controllability of the network. Using network virtualization's ability to manage and control network resources and statistical analysis of user behavior patterns, network resources can be allocated and use...
