SDN网络技术在虚拟化映射网络系统中的应用探究

Application of SDN network technology in virtualization mapping network system

随着信息化网络时代的快速发展,传统的单层物理网络模式已经不能满足网络服务需求,网络模式分布复杂且僵化日趋严重。网络虚拟化是解决当前网络架构僵化问题的核心技术,可以适应日益增长的网络用户数量和业务需求。因为SDN技术的集中化控制思想与网络虚拟化的集中控制思想相统一,对网络虚拟化的实现有重要意义。因此,文章对一种基于SDN技术的多域虚拟网络映射算法进行分析,并对虚拟化网络映射系统未来的发展方向进行探讨,为虚拟网络映射的研究提供理论借鉴。

With the rapid development of the information network era,the traditional single-layer physical network model can no longer meet the needs of network services,and the distribution of network models is complex and rigid.Network virtualization is the core technology to solve the problem of network architecture ossification,which can adapt to the increasing number of network users and business needs.Because the centralized control thought of SDN technology is unified with the centralized control thought of network virtualization,it is of great significance to the realization of network virtualization.therefore,this paper analyzes a multi-domain virtual network mapping algorithm based on SDN technology,and discusses the future development direction of virtual network mapping system,which provides a theoretical reference for the research of virtual network mapping.
