摘要

随着移动服务、大数据、云服务和人工智能的快速发展，传统网络服务已无法满足当前网络发展的需求，也无法解决当前网络存在的资源分配与调度僵化问题。而通过采用网络虚拟化技术，能够为用户提供灵活网络资源配置信息，从而减少网络成本，提高网络资源效率。采用混合线速率切分方式，把虚拟链路的带宽资源切分成不同的线速率传输，文章提出了基于混合线速率的虚拟光网络(VON)映射成本优化方法。仿真结果表明，与传统单线速率VON映射方法相比，文章所提出的混合线速率VON映射方法能够在网络成本、频谱隙占用数、光转发器和光再生器方面得到更好的优化和平衡。

Abstract

With the rapid development of mobile services

big data

cloud services

and artificial intelligence

traditional network services cannot no longer meet the requirements of current network development and solve the problems of the resource allocation and scheduling ossification in the current network. Therefore

by using network virtualization technologies

we can provide the flexible network resource configuration information for users to reduce network cost and improve network resource efficiency. The required bandwidth resources of each virtual link are divided into different transmission line rate by employing mixed line rate splitting. We propose an optimized cost approach for Virtual Optical Network (VON) mapping based on mixed line rate. Simulation results show that the proposed optimized cost approach of VON mapping based on mixed line rate can achieve better optimization and balance in terms of the network cost

frequency slot occupation

the configuration of optical transponders

and optical regenerators.
