摘要
为适应5G、云计算等业务宽带化持续发展,I P网络和光网络软件化、融合化成为发展趋势。针对I P网络和光网络缺乏动态交互机制的问题,首先分析了软件定义I P网络和软件定义光网络技术特征,探讨了将软件定义网络架构引入多层协同控制的必要性。然后设计了一种基于软件定义的"I P+光"层次协同控制模型,并比较分析了层次控制模型和现有对等控制模型的优缺点。最后分析了新的层次协同控制模型能够为大规模异构网络提供有效的层间交互,从而提高网络效率,降低网络运维成本。
With the rapid growth of the broadband applications, such as 5 G, cloud computing, software-defined-based and integration of IP network and optical network become an inevitable trend. To overcome the IP network and optical network without dynamic interaction, this paper first analyzes the architecture of software defined IP network and software defined optical network, and discusses the necessity of using software defined architecture in multilayer integration control. Then, a software-defined-based ＂IP＋optical＂ hierarchical control model is proposed, and the advantages and disadvantages between the hierarchical control model and existing control model are analysis. The proposed model provides efficient interlayer interactions in large-scale heterogeneous networks, result in improving network efficiency and reducing the cost of network operation and maintenance.
