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

Abstract

The invention provides a virtual network embedded system and method for cloud rendering in an optical data center network. The virtual network embedded system for cloud rendering in the optical data center network includes an optical backbone network, a rendering data center, an image storage data center and an image packed data center. The virtual network embedded method for cloud rendering in the optical data center network comprises the following steps: sending a virtual network embedded request to the optical data center network by a cloud rendering user; describing the virtual network embedded request in a modeling manner; sorting all cloud rendering tasks; performing virtual network embedding to current clouding rendering tasks; updating bottom layer optical data center network resource; counting consumed wave length amount and server amount; obtaining lower bound value ranges of consumed wave length amount and server amount of all cloud rendering tasks and verifying whether a current virtual network embedded operation is the optimal or not. Methods of server integration and traffic grooming are combined for node mapping and link mapping of the virtual network embedded request for real cloud rendering tasks and unreal cloud rendering tasks and the purpose of reducing rendering cost effectively is achieved.

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...
