Cloud rendering-oriented virtual network embedding system and method in optical data center network

Abstract

The present invention provides a virtual network embedding system and method for cloud rendering in an optical data center network. The system includes: an optical backbone network, a rendering data center, an image storage data center, and an image compression data center; and the method includes: a cloud rendering user transmits data to the optical network. The data center network issues a virtual network embedding request; models the virtual network embedding request; sorts all cloud rendering tasks; performs virtual network embedding of the current cloud rendering task; updates the underlying optical data center network resources; and counts the total number of wavelengths consumed. and the total number of servers; obtain the lower bound value interval of the total number of wavelengths consumed by all cloud rendering tasks and the lower bound value interval of the total number of servers; verify whether the current virtual network embedding operation is optimal. The present invention combines server integration and traffic grooming methods to perform node mapping and link mapping for virtual network embedding requests of real cloud rendering tasks and non-real cloud rendering tasks, thereby achieving the purpose of effectively reducing rendering overhead.

Description

technical field [0001] The invention belongs to the technical field of communication networks, and in particular relates to a cloud rendering-oriented virtual network embedding system and method in an optical data center network. Background technique [0002] Animation rendering is the process of converting a digital design into a vivid animation. This technology involves a large number of models such as geometry, lighting and materials, and often needs to be run on powerful computing programs. With the rapid development of precise modeling, a frame of animation usually contains thousands of geometric models, and each geometric model contains complex parameter settings. Therefore, animation rendering is very time-consuming, and the rendering time of a single machine is about two hours per frame. For an animation with a duration of 160 minutes, the rendering time will be as high as 2.88×10 6 Hour. Obviously, the core goal of animation rendering is to reduce rendering time...
