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

"5G+Wi-Fi 6" is a perfect match to redefine the wireless network, and the continuous development of "VR/AR+4K" has spawned more high-bandwidth applications. The wave of technological revolution has begun. The doubled transmission rate, massive data access and complex network management have brought unprecedented "pressure" to the campus network.

On the eve of the popularity of Wi-Fi 6 and the outbreak of IoT applications, the traditional gigabit networking mode has been difficult to meet the network needs of enterprises for "high speed, low delay and large capacity". To this end, after experiencing "100-gigabit optical fiber" and "gigabit to desktop", the campus network has officially entered the 10-gigabit era.

It is better to say ten thousand to ten thousand than to rise to ten thousand.

Looking back over the past decade, there is no doubt that 10 Gigabit Ethernet technology has come a long way. In July 2002, the Ethernet IEEE 802.3ae standard was officially released, which was originally expected to increase the bandwidth by 10 times and the cost by only 3-4 times compared with gigabit networks. However, in the deployment phase, we found that "cost" is the biggest stumbling block to this technology, which greatly limits its development and application.

Then, in 2006, 10GBase-T (802.3an-2006), a new 10 Gigabit Ethernet standard based on 100m twisted pair applications, was established. In 2010, the determination of the 40G/100G standard (802.3ba-2010) really marks the maturity of 10 Gigabit Ethernet technology. With the cost of 10 Gigabit modules and interfaces reduced year by year, port shipments are increasing year by year, the era of "10 Gigabit king" has come!

"ten thousand trillion is king", a familiar term, was put forward as early as 2012, and once became the hottest topic nowadays. At that time, due to the high price of 10 Gigabit network equipment, the user's idea of "rising to ten thousand" was shelved for a time. Today, seven years later, after a long period of technology accumulation and the emergence of high-bandwidth application blowout, the "10 Gigabit Campus Network" has once again stepped onto the "historical stage".

As Wi-Fi 6 crosses the technological rift and enters the stage of full deployment, the access bandwidth of each Wi-Fi 6 AP is upgraded to above 2Gbps (2.5G/5G/10G). According to the latest Dell'Oro Group research report, the campus gigabit port share will peak and begin to decline by 2021, while the 10 Gigabit port share will continue to grow, with a compound annual growth rate (CAGR) of 45.2%.

Huawei focuses on competitiveness and enlarges the park market

Today, the campus network is in the bottleneck period of full 10 gigabit / gigabit alternation. Relying on the leading advantage of independent research and development, Huawei has launched the "Special Action of 10 Gigabit Zhijian Park in China", which can be summarized as "3x2" mode, under the design concept of ultra-wide, minimalist, intelligent, safe and open, to provide enterprises with cost-effective 10-gigabit products and panoramic solutions.

Zhao Zhipeng, president of the network field of Huawei data communications product line campus, said: "2019 is the first year of large-scale commercial use of Wi-Fi 6. In the era of Wi-Fi 6, wireless access will become the default way of access to everything. With the rise of VR/AR/IoT/4K/8K ultra-high definition video applications, emerging applications move from local to cloud, from low interactivity to high interactivity, which poses new challenges to network delay and bandwidth. The upgrade of campus access from gigabit to 10 gigabit has become the mainstream consensus in the industry. Huawei's 10 Gigabit Smart Park solution, based on CloudEngine S series full 10 Gigabit switches, ultra-large capacity and ultra low latency AirEngine Wi-Fi 6 products and iMaster NCE management and analysis platform, provides enterprise customers with an ultra-wide, minimalist and intelligent campus experience. "

(1) Ultra-wide bearer: non-blocking, extremely fast access

Huawei builds an ubiquitous wireless network with AirEngine (https://e.huawei.com/cn/products/enterprise-networking/wlan/wifi-6) as the core), creates a wired network with zero packet loss with CloudEngine S series switches, and finally builds a fully automated, intelligent and open network management and operation and maintenance center through wired full 10 Gigabit and wireless full coverage.

In the field of campus switches, Huawei has launched a new generation of CloudEngine S series campus switches for enterprises, government, education, finance, manufacturing and other industries, creating a campus network with minimal management, stability and reliability, and business intelligence, covering access, aggregation and core switches, with a total of 16 new products.

In the core, aggregation, access and user layers of the network, products such as CloudEngine S12700E core switch, CloudEngine S6730-H/-S switch, S7700 / 8700 intelligent routing switch, S6720-SI multi-rate switch and AP7060DN access point can be used to ensure a smooth upgrade from Wi-Fi 5 to Wi-Fi 6 in the core, aggregation, access and user layers of the network to meet the network needs in the next 5-10 years.
