Allied Telesis, local and federal governments and the Organizing Committee of the Olympic Games, delivered a network infrastructure to support the needs of video monitoring traffic for the Rio Olympics. The solution featured the innovative technology-Ring, developed by Allied Telesis, called Ethernet Protection Switched Ring or EPSRing. With the EPSRing technology, a closed circuit network can be formed, providing link redundancy, and lower convergence by <50ms.

Motivation and Project Type

Constructing the network meant taking several parameters into consideration. It had to manage several devices easily. It had to reduce cost. And it had to build network redundancy to reduce the risk of downtime. The EPSRing topology met the requirements. It involved a concept that connected all devices to form a closed loop and link redundancy. The ring network helped add simplicity. All devices entered the network equally without impacting performance—no matter how many users. Uninterrupted data transmission was guaranteed, whether for VoIP or IP camera access/recordings. The following devices were considered for the project: core switches, responsible for ring topologies each venue; and switches de Borda, responsible for PoE + power supply and data transmission devices.


Since Rio de Janeiro was named the 2016 Olympics host, problems with crime in the city have received more attention. The Rio de Janeiro mayor acknowledged issues but guaranteed the safety of the event. The IOC also expressed optimism regarding both the city and country’s ability to address these concerns. A careful security project was planned to meet the IOC’s needs and requirements for the Olympic Games of Rio de Janeiro.


Each venue is provided with an MPLS link (provided by the operator), via a modem, which provides an Ethernet port that connects to the venue Core Switch for data transmission. This enables remote monitoring of all venues. The Core Switch is responsible for server connections and also for the Edge Switches venue. Edge Switches are interconnected between them. The last Switch Edge Switch  Core interconnects to form the ring  network EPSRing. Edge switches are also responsible for feeding devices via PoE and supplies data to the field devices. The optical single-mode fiber was used due to the need for connection of the devices over long distances.

The project network infrastructure is built to support traffic data, images, videos, voice, with a view to ensure the safety of the Olympics 2016. These audio and video products are the result of collaboration among Allied Telesis and the local and federal authorities linked to Public Safety and the Ministry of Justice and the Brazilian Olympic Committee (COB).
