SD-WAN has opened a new network

At present, Internet technology continues to develop, enterprises enter the era of digital transformation, business moves to the cloud, and corporate export traffic surges. While deploying new applications and developing emerging services, such as video conferencing and big data transmission, traditional leased line services can provide stable and reliable end-to-end service quality, but also have high price, long open period, low bandwidth utilization, etc. problem.

In today's "SD-WAN Industry Development Forum", Pan Feng, deputy secretary general of China Communications Standards Association, pointed out that SD-WAN, as an emerging service form, applies mature SDN/NFV technology to WAN transmission without changing. Based on the existing network architecture, it provides a manageable virtual network. Compared with the existing network, it has the advantages of flexible traffic scheduling, simple network and low cost of operation and maintenance, and opens up a new network application blue ocean.

Pan Feng said: "To this end, China Communications Standards Association's TC610 (namely SDN/NFV/AI Standards and Industry Promotion Committee) is an important industrial organization in the field of SDN, NFV, and network AI, and is working with all parties in the industry to implement and release it as soon as possible. The technical standards for related evaluations include the SD-WAN Key Indicator System and the Software-Defined Wide Area Network (SD-WAN) Test Method.
