随着全球范围加大了对软件定义网络(SDN)的关注和重视,网络领域也迎来了新的改革。SDN能在一定程度上提高目前网络的可控、可管和灵活性,将网络服务提供者的运营成本(OPEX)和投资成本(CAPER)大幅度降低。SDN的发展方向正在朝着更智能、更开发、更全面前进,能为未来网络的发展提供更好的基础。而大量专业技术人员的需求量是SDN技术和应用发展脚步加快时急需解决的问题。
With the increasing attention and emphasis on Software Defined Networking (SDN) around the world, new reforms are also embraced in the area of networking. SDN can improve the controllability, controllability and flexibility of the current network to a certain extent, and greatly reduce the operating cost (OPEX) and investment cost (CAPER) of network service providers. The direction of development of SDN is moving toward smarter, more developed and more comprehensive, and can provide a better foundation for the future development of the network. The demand of a large number of professional and technical personnel is an urgent problem to be solved when SDN technology and application development accelerate.
