SDN is a new framework for future networks

SDN, or software-defined networks (software Defined Network), refers to the use of software to dispatch and manage networks. SDN changes the traditional network layer and data link layer network equipment needs administrator configuration settings to pass the data after the operation mode, proposed to the management system (control plane) from the various devices extracted, through the software unified scheduling and control, and network equipment dedicated to data communication work (forwarding plane). SDN solves many problems with existing networks.

SDN is a short-term multi-development, the basis of 5G communication

We believe that in the short term, SDN will be a popular, professional, unified, standardized, open source, such as the five major development trends.

In the long run, SDN is the foundation of 5G communication. The 5G is designed for a variety of applications, with varying requirements for capacity, reliability, and latency in different scenarios. While these scenarios need to be implemented on the same network, good network architecture is the basis of diversified requirements. As a key element of the 5G architecture, the optimization and evolution of 5G core network is one of the important research topics in industry.

The flexible control of network traffic can become the switching mode of 5G different scenes in the future, improve the overall access performance of the network for complex scenes, and orchestrate network resources on demand, realize network slicing and flexible deployment, meet the end-to-end business experience and efficient network operation demand.

SDN has already appeared in 5G official documents "5G Wireless technology Architecture", "5G Network Technology architecture" white Paper, "5G Network architecture Design" white paper all highlight the importance of SDN for 5G meaning.
