The Beijing Olympic Committee proposed a “Digital Olympic Community Action Plan” aiming to provide an outstanding living environment for all athletes and media workers. The plan fully stood by the concept of “High-tech Olympics and People’s Olympics”. In addition to the high-quality apartments, various facilities such as interactive kiosk, telephone booth, recreation center, clinic, emergency center, police station, car park and media center were also parts of the village design. Ruijie Networks, as a leading network device and solution provider, stood out among competitors bidding for the Olympic project with a professional team of network specialists. Ruijie received positive comments from the Committee and one read, “Ruijie provides an advanced and open smart information platform, which fully guarantees stable network operation. It also totally satisfies the requirements of the ‘Digital Olympic Community Action Plan’”. Ruijie hence was chosen as the solution provider for all the network projects at the Beijing Olympic Village.  
1.    The network was one of the core infrastructure facilities for all application systems in the Olympic Village. As a platform supporting complex systems, its functions and operation had to be unified. It also had to offer a high-speed and high-bandwidth platform for various applications (e.g. multimedia).  
2.    The network of the Beijing Olympic Village was divided into intranet and extranet with physical isolation. The devices involved in the project were for intranet deployment only. The intranet was an open network serving all athletes, journalists and staff. The deployment of access switches was relatively more complicated and the risk level was difficult to evaluate. Hence, the requirements on stability and anti-attack capacity were very demanding.
3.    Based on the features of various service systems under the whole network model, the solution deployed VPN, ACL, commercial passcode, network access gateway, digital certification authentication, security auditing for enhanced network security.
4.    The project aimed to create a highly efficiency network handling the demand for data services from all guests during the event.
5.    The solution was required to offer redundancy according to the number of guests and applications. Each room in the village was equipped with sufficient ports for network access (except the server room). The rooms for leaders, VIPs and the conference room were installed with additional ports for flexible application.

Ruijie adopted a modular design to create a layering network model for easy troubleshooting and future expansion. The solution deployed a three-layer architecture with core, aggregation and access layers based on the existing cabling design and the network coverage requirements.
Core Zone: The major function was to achieve optimized transmission between core networks for high-speed forwarding. The core zone was deployed with 2 core 10GE switches - RG-S6810E. The core nodes were linked together via 2 10GE links for dual redundancy and load balancing. It also connected with the server through a Gigabit link.
Aggregation Zone: Aggregation switches were responsible for connection between the core and access zones. Dynamic routing protocol achieved link backup and load balancing. The solution deployed 5 10GE switches - RG-S6806E - connecting the two core switches via 2 10GE links.
Public Infrastructure Zone: The infrastructure platform played a crucial role in the whole Olympic Village network. In this solution, the infrastructure network consisted of 51 S2924G switches connecting to the RG-S6806E switch via the Gigabit copper ports.
Residence Zone: In the access layer, the solution offered users with network access via the access switch in the wiring room. The 10/100/1000Base-Tx ports were distributed to users’ desktops. Each access switch connects with the aggregation switches via the Gigabit link. Access layer devices only required Layer 2 switching. In this solution, S2924G switch was chosen to act as the access switch.
Network Management Zone: The servers here were responsible for management over network devices, systems, access users, etc. Teaming up with Ruijie’s network management software STAR-VIEW, the solution delivered unified and effective management over the whole system.

The features of the network platform at the Beijing Olympic Village were:
1.    10GE Core and Gigabit to Desktop
Smooth network performance was guaranteed.
2.    Dual-core Design
With the dual-core technology, it did not only offer exceptional redundancy capacity, but also enabled load balancing for center data communication. The solution reduced workload of the center and offers stability and reliability of the core layer. The two core switches achieved link aggregation with 802.3ad, reaching bandwidth up to 40G. The dual-core design was achieved by technologies such as VRRP and 802.1S.
3.    Distributed Routing Design
The two RG-S6810E core switches and 6 RG-S6806E aggregation switches formed the whole network routing via OSPF. Routing was distributed among 10GE switches of the buildings. It reduced the routing workload of the core devices. The results were significant.
4.    Efficient Anti-virus Control
Comprehensive anti-virus features were available between buildings’ core and aggregation products. A typical example included Blaster Worm. With hidden ICMP packets, it masked the relevant virus ports. This could also prevent attacks such as DDOS and ARP.
5.    Port Binding with MAC and IP Addresses
The flexible binding greatly enhanced network access security. IP address conflict, embezzlement and abuse would hamper the normal network operation. An efficiency solution was required to solve such problems.
6.    All-time Network Management
Network administrators could manage SNMP devices based on international standards. The solution enabled monitoring over network topology, device traffic and operation anytime.
7.    High Expandability
The modular design guaranteed expandability. From core and aggregation to access devices, there was also enhanced expandability for future development.
