Ruijie Wi-Fi Safeguards the Computing Conference 2016

On October 13-16, 2016, the Computing Conference 2016 was solemnly held in the International Convention Center of Yunqi Town. As the world's top-class cloud computing summit, the Computing Conference 2016 hosted by Alibaba Group sets a new record in scale: Over 40,000 people participated in the conference, and more than 7 million people watched the conference via online live broadcast. To ensure a smooth WiFi network for the conference as well as the display effect of cutting-edge technologies, the sponsor of the conference selected Ruijie Networks again based on last year's successful cooperation and Ruijie's rich experience in network deployment for ultralarge-scale conferences.

Facing the challenges from doubled wireless users, a sharp rise in access density, and a considerable quantity of VRs, ARs, MRs, and other smart devices to be deployed, the Ruijie wireless team once again provided high-quality WiFi signal coverage for the site of the Computing Conference, living up to the honor and reputation of "true power of wireless network construction" with satisfactory user experience.

The "Veteran" Meeting New Challenges and Providing Full Wireless Signal Coverage

From the gathering of several hundreds of webmasters and grassroots six years ago to a convention with more than 20,000 participants in 2015, and 40,000 participants in 2016, the Computing Conference has become a window for the world to witness China's new Internet technologies. The Computing Conference 2016 of an unprecedented scale covered 10 summits, hundreds of industry and technology forums, and more than 600 lecture themes throughout 4 days. The innovation exhibition and experience area with tens of thousands of square meters demonstrated the cutting-edge technologies nowadays. Live broadcast was provided at the official website and by media throughout the conference to meet audience's expectations, and advanced technologies such as quantum communication, artificial intelligence, and biological recognition were exhibited in the conference. All these required Ruijie to ensure a smooth WiFi network without any errors in the case of ultra-high concurrency, ultra-dense access, and overload.

The Computing Conference 2016 of an Unprecedented Scale

The wireless coverage deployment involved a complex and irregular building structure, which greatly increased the difficulty in field survey. Moreover, the time was short, and there were only ten days left from field survey to the project completion. This brought great challenges to Ruijie.

Field survey was first implemented, which is the core and foundation for the ultralarge-scale wireless network construction. Based on Internet access requirements and crowd density in the entrance registration area, main conference site, main exhibition area, forum area, dining area, rest area, and media area, Ruijie adjusted signal transmission to the optimal state and provided the most appropriate deployment and planning solution for full WiFi coverage of the Computing Conference via the field environment inspection and bitmap analysis. In field survey phase, Ruijie engineers made use of their experience in application scenarios and deployment environment control. They customized real-name authentication for interconnection with the public security system and used suspended high-density AP design for the exhibition hall and main conference site. In Ruijie solution, APs were deployed in different positions based on scenarios, with some APs suspended and some APs installed under seats. The favorable positions helped the APs provide high-quality coverage services.

Traffic Burst + "Black Technologies" Testing the Network Optimization Capability

It is uneasy to safeguard the smooth WiFi network access of 40,000 participants. After wireless APs were deployed, dynamic load balancing and dynamic traffic balancing were further needed to ensure the optimal experience for each wireless network user, which is the ultimate challenge of wireless optimization. In view of this, Ruijie provided innovative high-density access APs (RG-AP520 as the representative) for full coverage together with the wireless network optimization tool WIS.

For example, in the media area of the main conference site, almost every reporter carried two or three wireless devices, so that they can access the network, transmit reports, watch live broadcast screen at the same time. This will inevitably cause traffic bursts. For this, Ruijie applied the new-generation wireless intelligent service ecosystem WIS. The one-click optimization enables the WIS to automatically complete the adjustment of channels, power, speed, and other key parameters, thereby ensuring the optimal wireless access experience for users in high-density scenarios.

In the exhibition area, innovative technologies became the focus of numerous participants, including fields related to multimedia, VR, AR, IoT, life sciences, industrial manufacturing, finance, and enterprise services. All these smart products required a high-quality WiFi access network, and the network required by these devices differed from the network required by common users in that, in addition to fast downlink transmission, equivalent high-speed uplink transmission was also required. For this, Ruijie further optimized APs deployed in these booths, adjusted key parameters such as channels, power, beacon frame signal strength, and receiver sensitivity, and checked the PoE access lines one by one, to fully demonstrate the amazing effect brought by these "black technologies".

Innovative Scenario Deployment Demonstrating "True Power of Wireless Network Construction"

At the site of the liveliest party, the "true power" of Ruijie in wireless services was fully embodied. The actual speeds at multiple points in the stand area reached the full speed, with the average downlink speed ranging from 45 Mbps to 60 Mbps, and the average uplink speed ranging from 30 Mbps to 50 Mbps. The 5G access proportion reached 86%. With the excellent performance of RG-AP520, the CPU usage was only 2% when the number of users carried by a single AP exceeded 100. At the party, a climax came as Jack Ma was singing, upon which online celebrities and hundreds of participants on site recorded and uploaded the videos concurrently. Nevertheless, Ruijie successfully ensured superb network experience for users without any video stalling.

Behind the cool experience are a rigorous technical solution and first-class products. To ensure the high reliability of network transmission, Ruijie used the core switch RG-S8605E to build the core layer, and applied the Virtual Switching Unit (VSU) technology to directly connect the bundled chassis to the core device in the equipment room, thereby guaranteeing the high-speed forwarding of data traffic for 40,000 participants on site. In addition, at the network egress, Ruijie used the full-service core router RG-RSR7708 as a backup link egress, to guarantee the network security. The high-density PoE+ switch RG-S2910XS-E can remotely supply power to all indoor and outdoor APs, and provide high bandwidth to ensure that wireless Internet access data is smoothly forwarded to the core switch.

Winning Reputation from Practice and Building the TOP1 Wireless Service Brand

Continuously challenging oneself in practice is the best way to steel one's strength. From the "Computing Conference 2015", to "Global Internet Technology Conference (GITC)", "Suning Summer Party 2016", and "Tencent Global Partner Conference (TGPC) 2016", Ruijie Networks, as the Top 1 wireless service provider for large conferences in China, provides excellent on-site wireless network services and wins unanimous praise.
