Background

Tianjin Olympic Center Stadium was one of the sponsor venues of 2008 Beijing Olympic Games and hosted football preliminaries of the 2008 Summer Olympics. Located in the southwest of Tianjin, the stadium covers 78,000 square meters and can accommodate up to 80,000 audience. China Mobile and China Network Communications (CNC) were communication service partners designated by the Beijing Organizing Committee for the Olympic Games (BOCOG), which provided communication services for the matches in Tianjin and assigned 2 Gbps bandwidth for access to the Olympic Sports Center via different routers. Ruijie Networks, as a leading network equipment solution provider in the industry, deployed a campus network inside the stadium to ensure that journalists can publish instant reports, thereby implementing real-time live broadcasts and efficient communication.

Requirements

A great number of journalists gathered during the matches, and they basically published reports across the globe at the same time. Therefore, network bandwidth must be ensured. The entire backbone network used Gigabit fiber links to implement efficient switching.

As there were a great number of users, and both wired and wireless solutions were used, the identities of all users for accessing the network must be valid and unique.

For this, the basic information of users, such as IP addresses, MAC addresses, and port IDs, must be bound to prevent user account conflicts and reduce the maintenance workload during the matches. 

Due to cabling difficulties in the stadium and numerous portable computer users during the matches, it was necessary to deploy a wireless network on a large scale. 

The entire network must be capable of protecting against viruses to prevent network interruptions.

Solution Design

Solution Characteristics

High-speed data transmission: Backbone switches provide high-speed backplane bandwidth and packet forwarding rates, meeting the requirements for heavy data traffic processing in the stadium.

High stability and reliability: Backbone switches use the unique three-plane separation technology to assign exclusive resources to the coexisting data plane, control plane, and management plane, so that the planes do not interfere with each other.

High security: Access switches support rich interface security features, which help eliminate cyber attacks, such as address phishing, ARP spoofing and virus propagation. Wireless APs support multiple encryption modes. These encryption modes are implemented via hardware, which does not affect the forwarding efficiency. Convergence-layer devices have multiple embedded security defense mechanisms, and can isolate scanning sources in the Intranet from the network.
