Shulou(Shulou.com)06/03 Report--

At IDC's annual orientation conference, Mehra, network infrastructure analyst and vice president of IDC, said, "since 2016, SD-WAN has seen incredible market growth, and the natural process of network development inevitably leads to advantages. SD-WAN and edge computing are interdependent. Edge computing requires a dynamic WAN, and SD-WAN benefits edge computing use cases. The two are interrelated, just like chickens and eggs. "

Due to the development of other technologies, enterprise networks will see significant changes and progress throughout 2019. Some major network trends include 5G, 802.11ax (or Wi-Fi 6), and Gigabit Ethernet (GbE). Overall, automation and its real-time capabilities play an important role in all of these deployments.

Network Trends worthy of attention

Although many of these network trends will be deployed in 2019, their impact on the network industry will be widely seen.

5G and 4G LTE. According to Mehra, 5G is fast approaching. By the end of 2019, 5G networks will be available in some cities around the world, while companies will launch 5G networks in the experimental phase, focusing on 5G fixed wireless networks.

Mehra said that the wireless 5G has a broadband-like function, coupled with automation, will make 5G a "once-in-a-lifetime event." Automation adds speed and flexibility to 5G capabilities, making it a compelling use case for enterprises. The large-scale launch of 5G this year is not realistic. As we wait for the full development of 5G, the use of 4G LTE by enterprises is becoming more and more common.

In the past few years, 4G LTE has matured, making it a technology that can compete with traditional business-grade wireless technologies.

Mobile consumers may not see the benefits of 5G until 2021.

"in order for users to benefit from 5G, everyone needs a phone that supports 5G," Mehra said. "We have two or three years left."

The edge of the network. With the increase of network complexity, this advantage becomes more and more important. Mehra says end-to-end visibility needs to be automated. Whether it is on the enterprise side, the Internet of things, or cloud computing, it is the key to ensure that the network works properly in several different use cases.

"Healthcare, utilities, mining and manufacturing, all of these IT-related actions take place at the edge of the network," Mehra said. "to be successful, you need a more dynamic WAN and connectivity."

Automation enables dynamic WAN, real-time response, and enhanced customer experience. Mehra added that because of the remote communication capabilities of 5G, automation combined with 5G wired or wireless networks can benefit the edge.

Another technology that benefits the edge of the network is SD-WAN, which itself is a dynamic WAN.

SD-WAN . According to Mehra, SD-WAN is a building block for autonomous networks, but automation also applies to SD-WAN. The SD-WAN market is growing, and although it has not yet reached the mainstream, its time is coming fast. As automation can be built into software, the need for automation has contributed to this growth.

"as the market shifts to a more comprehensive SD-WAN approach, we think it will be the driver of a new edge architecture," Mehra said. "while SD-WAN focuses on connecting pipes, the WAN is the pipeline that connects you."

SD-WAN and automation allow for more dynamic edges, which closely connect these network trends.

Wi-Fi 6 and 400 GbE. The new Wi-Fi standard, also known as 802.11ax, is expected to be released by the end of 2019. Wi-Fi 6 promises real-time response and aspects, as well as multi-user MIMO and orthogonal frequency division multiple access (OFDMA).

"on a customer-by-customer basis, using MU-MIMO and OFDMA,Wi-Fi 6 provides a first-class experience and automatically changes its own architecture to support this." "I think the autopilot network will enter the Wi-Fi era," Mehra said.

Although Wi-Fi 6 boasts agility, scalability and real-time responsiveness, Mehra says that multi-GbE can meet the needs of enterprises at this time.

"the usage of 400 GbE is clear for the data center, but I think even with Wi-Fi 6, the number of GGE in the enterprise is enough to reach 100 GbE." He said.

Most 400 GbE deployments will begin in 2019, with 400 GbE switches starting as spine or backbone switches in very large data centers, as well as spine or backbone switches in private and public cloud data centers, Mehra said. Wi-Fi 6 and 400 GbE won't be mainstream until 2023.

Please think twice before deployment

Despite the hype about these technologies, Mehra says he encourages companies to step back and not get carried away by new online trends. In general, each organization must weigh its options when deciding on the best tools and technologies.

"with the emergence of all the new technologies, there is a lot of hype," Mehra said. "the market is exploding, but we need to be pragmatic and cautious to launch."
