DIGITAL INFRASTRUCTURE AWARD 2017 CASE STUDY
Daejeon Convention Centre (DCC)
The Daejeon Convention Center (DCC) is the largest convention center in Daejeon Metropolitan city and Chungcheong providence in South Korea. Over 400 national and international conferences, meeting and exhibitions are held there every year. The DCC is supported by a cross-connected digital infrastructure circuit which prevents network interruption and offers a unique level of security provided by the government free of charge to the organizers and users of the DCC.
The DCC is owned by the Daejeon city government. It is the largest convention center in Daejeon Metropolitan city and Chungcheong providence in Korea. Over 400 national and international conferences, meeting and exhibitions are annually held there every year.
Daejeon is a city well-known for science and technology, it is equipped with the nation's top-speed and most stable digital infrastructure, operated by KT Corporation, one of the biggest telecommunications company in Korea.
The DCC is supported by a cross-connected digital infrastructure circuit which prevents network interruption. This line is the network used by government agencies and offers a unique level of security. This would normally cost more than €155,000 per line, per year and is provided by the government free of charge to the organizers and users of the DCC.
WINNER’S MAIN FEATURES
WINNER’S APPROACH TO DIGITAL INFRASRUCTURE
There are two MDF 80GBps backbone switches. The IEEE 802 standard band that provides a data rate of 1sec / 10GBps per device is duplicated (two lines). The currently active internal bandwidth is 60GBps.
Wireless: It uses 2.4Ghz/ 5Ghz dual channel through USA XIRRUS's 33 wireless APs. According to the AP manufacturer's manual, our network can connect 15,500 users at the same time.
LAN: Fundamentally there is no limit to simultaneous connections. Physical limits may exist, but logical limits do not.
MDF 10GBps * 2 8 port backbone switches, 10 IDF 10GBps Layer2 24 ports that can be directly connected to fiber optic cable, 12 1GBps Layer2 48 ports, and 1GBps 24 ports.
With 30 switches, it is possible to directly connect 1,550 PCs or devices with CAT.6 UTP cable without any additional installation.
Daejeon Convention Center (DCC) introduces 33 units equipped with 4~16 radio stations to 1 AP developed by USA XIRRUS and adopts distributed intelligent architecture based on XIRRUS wireless controller to provide network intelligence such as traffic processing ability, which is integrated into one AP and distributed to the network connection nodes. By concentrating on the centralized controller of the existing 'Thin AP+controller', it is possible to control the instability of traffic such as delay and jitter. It is optimized for medium sized conference hall and large exhibition hall and enable to provide many users with stable use of wireless internet even in the space under constraints. L2/L3 roaming service is also available for seamless network access when moving. With this infrastructure, DCC has a wireless environment that allows more than 5,000 simultaneous users to access in a comfortable environment, which is the most advanced wireless infrastructure in Convention Center in Korea. DCC supports 802.11a/b/g/n at 2.4GHz/5GHz and full wireless 802.11ac and 1.3 Gbps of radio bandwidth per radio, providing fast Wi-Fi connectivity.
In order to overcome the shortcomings of wireless internet with weak security, DCC applies the Korea Research Environment Open NETwork (KREONET : Korea Research Environment Open NETwork), which is operated by the government, as the main line of wireless Internet. This line is the network used by government agencies and maintains the strongest security policy. By introducing the Global Wireless Roaming Service (Eduroam : DUcation ROAMing) ID authentication server, users around the world can use the wireless ID for free using the global ID. In order to provide a pleasant wireless Internet environment, users who do not have an Eduroam ID are allowed to use free internet at a certain rate (DCC FREE Wi-Fi). DCC's wireless Internet has also adopted a handoff service that consists of wireless cells so that users can continue to use the Internet without being disconnected even when moving the meeting rooms within the building(DCC).
