Live Broadcasting New Model! III introduced SDN technologies and conducted real-time video traffic analysis during 2017 Summer Universiade
Picture Description: During Universiade, III introduced SDN technologies and conducted real-time video traffic analysis. The picture shows the structure of management and test procedures.
Picture Description: With the support of Department of Industrial Technology, Ministry of Economic Affairs, III Smart System Institute researched and developed "Real-time Video Traffic Analysis and Management System" and conducted "2017 Universiade Video Delivery Service SDN Technology Verification Project" covering all areas in Taiwan, which utilizes SDN technologies to verify the guaranteed dynamic broadband. The picture demonstrated the real situation of test broadcasting.
While the competitions of 2017 Summer Universiade are in full swing, for those who can't be at present, they could only rely on live TV broadcasting and internet live video streaming to watch the games instantly. However, in the middle of these contests, if the transmission got delayed or lags appear at critical moments, the audience could do nothing but to suffer the blank moments with the ache in their hearts hopelessly. In order to prevent the tragedies from happening repeatedly and upgrade the technologies for the quality of future competitions, III Smart System Institute applied SDN (Software defined network) technology to the broadcasting of Universiade games with the support from the project proposed by Department of Industrial Technology (DoIT), Ministry of Economic Affairs. Consequently, during Universiade, "2017 Universiade Video Delivery Service SDN Technology Verification Project" was conducted in each area in Taiwan to try out the new approach of broadcasting.
The HD videos signals of Universiade were provided by Chinese Television System (CTS) on the scene and then transmitted from the node at National Taiwan University (NTU) to the SDN backbone network of National Center for High-Performance Computing where the images were sent by the latest technologies with top speed to satisfying the need for multi-point delivery service broadcasting live exciting games. In face with the real application situation of video streaming, III utilized current SDN automated test platform to develop the tested combination structure which selected SDN switches fitting the actual situation so as to meet Open Flow standard in which SDN dynamic network broadband is guaranteed. Using self-developed "Universiade Video Streaming Test System", the lab of III could conduct real time video traffic analysis and management focusing on the viewers of these videos. Also, while providing SDN dynamic broadband network guarantee and testing the technologies of extra bandwidth sharing, the lab is able to come up with the best broadcasting solution applying the most efficient approach from its analysis.
In recent years, HD video streaming service has become an indispensable part of modern people's lives. Applying SDN technologies, professionals could make the best decisions while managing and dispatching internet resources in cope with various dynamic network demand. SDN technologies could be called the critical technologies to accomplish the goal of 5G network. There is no better way to find out the true capability of SDN technologies by broadcasting an international competition like Universiade. Not only could it help build the domestic software business models related to internet innovation but also offer the best testament for the products and services able to go through the trial of the real business world.
"2017 Universiade Video Delivery Service SDN Technology Verification Project" further exhibited 3 imperative features: Firstly, this is the first test network in Taiwan dealing with long distance software-defined video delivery service. The network combines current 100Gbps north and south bound backbone network of National Center for High-Performance Computing and 4G+ experimental network to dispatch video images with the help of domestically produced software and hardware. Secondly, integrating SDN network and current internet network, professional staffs can conduct partial replacement in accordance with the requirements of real situations. Thirdly, the idea of multi-point delivery can be realized and the quality of the service could surpass that of IP/MPLS(Multi-Protocol Label Switching) * network.
To successfully complete the broadcasting test of Universiade, III, SDN/NFV coalition, Board of Science and Technology, Executive Yuan, Industrial Development Bureau, Ministry of Economic Affairs, Taipei City Government, 2017 Summer Universiade Organizational Committee, and Chinese Television System all work collectively. The project also gathers domestic telecommunication enterprise Chunghwa Telecom, two major research institutes Industrial Technology Research Institute and National Center for High-Performance Computing, and network communication manufacturers such as Delta Networks, EstiNet Technologies, and Accton Technology. By applying whole new technologies, these organizations could hand in hand facilitate major international competitions and promote advanced internet technologies at the same time so that the vertical integration of domestic SDN industry could progress smoothly, which is beneficial to the acceleration of service commercialization and industrial development. It is expected that domestic enterprises could apply the mature technologies and enter the global markets.
*MPLS is a technology applying tags to activate high speed and efficiency transmission of information on open networks. One of its features is able to introduce connections in a wireless network. The most important advantage of it is that the technology greatly reduces the complexity of the internet and is compatible to various mainstream internet technologies so as to decrease internet cost and guarantee QoS and security while providing IP service. The technology has traffic engineering capacity.
