With the development of cloud computing, mobile applications and globalization, the disadvantages of MPLS dedicated line of vertical and horizontal enterprise private network for 20 years are gradually exposed, MPLS private line is more and more difficult to meet the business development needs of enterprises, while cloud computing, SaaS and mobile applications have natural Internet properties.

Why can the "Internet" replace the dedicated line?

The continuous development of the Internet has laid the foundation for replacing the MPLS dedicated line. With the blessing of SD-WAN, enterprises can use Internet resources to build corporate networks and expand their business more economically and reliably. Therefore, want to replace the MPLS dedicated line, SD-WAN+ Internet, one can not be less!

This article will focus on the part of the Internet, the rapid development of the Internet in China, and the continuous upgrading of the infrastructure and quality of the Internet, which has laid a good foundation for replacing the MPLS dedicated line.

two。 Speed-up and fee reduction of broadband network infrastructure compared with MPLS lines, the Internet is cheap and easy to obtain. In terms of price, the data show that in the first half of 2019, the average charges for broadband and private lines for small and medium-sized enterprises were 525 yuan / Gbps and 13291 yuan / Gbps respectively. From the perspective of international comparison, the average tariff level of fixed broadband and the price of fixed broadband products in China are ranked 13th and 16th respectively, which are at a lower level in 71 countries in the world. Although the price of the Internet is falling, the speed is increasing. According to the report on the status of Broadband Speed in China, the average download rate of China's fixed broadband network reached 37.69Mbit/s in the third quarter of 2019, an increase of 6.3% over the previous quarter and 12.7Mbit/s over the same period last year, an annual increase of 50.8%.

3. The performance of backbone network continues to improve and tends to the international level. since the beginning of this year, the capacity of backbone networks in China has been continuously expanded, and the performance of inter-network delay and packet loss rate has been continuously improved. As of June 2019, the inter-network capacity of China's backbone networks has been expanded by 480g, and the inter-network delay has decreased to 39.62ms, a decrease of 38.1% compared with 2015, and the packet loss rate has dropped to 0.11%, a decrease of 89.2% compared with 2015.

4. 5G launched a new commercial journey on October 31st, the three major operators officially launched the 5G package, which marks that China has officially entered the 5G commercial era, while 5G has three major application scenarios, namely eMMB,uRLLC and mMTC, according to different scenarios, you can choose different solutions.

EMBB emphasizes the speed of the network. If the rate is above 10Gbps, it will serve the eMBB scenario. URLLC emphasizes low delay and high reliable communication. Such as vehicle networking, UAV, industrial Internet and so on, in such scenarios, there is a high demand for network delay and reliability. MMTC, which has a large number of terminals per unit area, needs the network to support the simultaneous access of these terminals, which refers to the mMTC scenario. In addition to its own quality improvement, another important reason why the Internet has replaced the MPLS dedicated line is that it is easy to obtain and can connect to cloud services. As we all know, the opening time of the Internet is very short, and it can be completed within 1 day, which is much lower than that when the dedicated line is more than 30 days. Internet to replace MPLS dedicated line also faces challenges, such as security, network optimization and so on, which need to be overcome by SD-WAN technology, which is already a mature landing technology. It can be said that the era of the Internet replacing the MPLS dedicated line has come! In the case of the Internet replacing the dedicated line, there have been successful cases of extreme interconnection. (space is limited, the next issue will introduce in detail the blessing effect of SD-WAN on the Internet through a case.)

The value of SD-WAN is to enable enterprises to make better use of the ubiquitous Internet and reduce their dependence on expensive MPLS lines. And the Internet of enterprise network will also be an irresistible spring tide. The ultimate interconnection will also adhere to the Internet-based technical route and networking mode, so that enterprises can be unimpeded in the change.
