The advantage of 10GE and the disadvantage of GE
Hello everyone! On the eve of the popularity of Wi-Fi 6 and the explosion of IoT applications, traditional gigabit networking cannot meet enterprises’ requirements for high-speed, low-latency, and large-capacity networks. Therefore, after “100M optical fiber” and “Gigabit-to-desktop”, campus networks have entered the 10G era.
Looking back over the past decade, 10 Gigabit Ethernet has come a long way. In July 2002, the IEEE 802.3ae standard was officially released. Compared with the gigabit network, the IEEE 802.3ae standard was expected to increase the bandwidth by 10 times and the cost by only 3 to 4 times. However, during the deployment phase, we found that “cost” was the biggest stumbling block for the technology, limiting its development and application.
Then, in 2006, a new standard for 10 Gigabit Ethernet based on 100-meter twisted-pair applications, 10GBase-T (802.3an-2006), was established. In 2010, the 40G/100G standard (802.3ba-2010) is determined, which marks the maturity of 10G Ethernet technology. As the cost of 10GE modules and interfaces decreases year by year, and the number of port shipments increases year by year, the era of 10GE is the king.
The familiar term, “King of 10 gigabytes”, was proposed as early as 2012 and has become the hottest topic of the moment. At that time, because of the high price of 10GE network equipment, users to “thousand to ten thousand” idea was shelved. Today, after seven years of technology accumulation, the 10GE campus network has once again entered the historical stage with the emergence of high-bandwidth applications.
As Wi-Fi 6 crosses the technology rift and enters the full deployment phase, the access bandwidth of each Wi-Fi 6 AP is upgraded to 2 Gbit/s or higher (2.5 Gbit/s, 5 Gbit/s, and 10 Gbit/s). According to the latest Dell’Oro Group research report, by 2021, the proportion of gigabit ports on campus will peak and begin to decline, while the proportion of 10-gigabit ports will continue to grow at a compound annual growth rate (CAGR) of 45.2%.
Huawei Focuses on Competitiveness and Expands the Campus Market
Today, the campus network is in the bottleneck period of the full 10GE/Gigabit alternative. Based on its own R&D advantages, Huawei launched the “China Region 10GE Smart and Simple Campus Special Campaign”. The “3 + 2” model is designed with ultra-broadband, simplified, smart, secure, and open design concepts. Provides cost-effective 10GE products and all-scenario solutions for enterprises.

Zhao Zhipeng, president of the campus network domain of Huawei Data Communication Product Line, said, “2019 is the first year of large-scale commercial use of Wi-Fi 6. In the Wi-Fi 6 era, wireless access will become the default access mode for everything. With the emergence of VR, AR, IoT, 4K, and 8K ultra-HD video applications, emerging applications are moving from local to cloud, and from low-interactivity to high-interactivity, posing new challenges to network latency and bandwidth. Upgrading the campus access network from gigabit to 10GE has become a mainstream consensus in the industry. Huawei’s 10GE intelligent campus solution is based on CloudEngine S series 10GE switches, AirEngine Wi-Fi 6 with ultra-large capacity and ultra-low latency, and iMaster NCE converged management, control, and analysis platform. Provide enterprise customers with an ultra-broadband, simplified, and smart campus experience.”
