Shandong Unicom builds all-optical computing network to release cloud computing capability.

In the digital economy society, computing power is productivity, which has become the knowledge of the whole industry. The White Paper of China Computing Power Development Index by China Information and Communication Research Institute points out that every input of computing power 1 yuan will drive 4 yuan's economic output. In the era of "computing power", all-optical networks with high quality, certainty, high security, low delay and low jitter are indispensable for high-end cloud computing and IDC services. Building an all-optical computing network with the integration of light and cloud is to build a high-quality deterministic computing network.

China Unicom is one of the telecom operators who put forward the concept of computing network earlier in the industry. 20 19, 1 1, China Unicom took the lead in publishing the White Paper on Computing Networks. Shandong Unicom has been practicing the concept of CUBE-Net 3.0 of China Unicom, and based on the customer experience, through the concept of all-optical computing network, it has built the infrastructure of smart cloud city, transported the power of cloud computing to thousands of industries, improved the service capacity of smart city, and helped the regional integration development of the three economic circles of provincial capital, Jiaodong and southern Shandong.

Shandong Unicom took the lead in launching "SD-FAST" intelligent optical network in 20 19. In 20021year, it proposed to move from intelligent optical network to intelligent optical cloud, started the construction plan of sixteen cities of intelligent optical cloud, and gradually evolved into an all-optical computing network, supporting fast online services and flexible expansion needs of end users. Through all-optical scheduling OXC platform, ASON service automatic recovery technology, flat network architecture and many other projects, Shandong Unicom has realized optical cloud collaborative management and control based on "self-developed cloud network optical cloud coordinator +SDN intelligent management and control controller", and relied on China Unicom's centralized business support system to realize one-stop access from order acceptance to business distribution. In the later stage, the AI analysis and prediction technology of traffic will be adopted to realize the automatic elastic expansion and contraction of business traffic.

Up to now, Shandong Unicom's intelligent optical network has been widely used by customers in various industries such as party, government, army, finance, medical care and manufacturing. One of the typical applications is to quickly transport the computing power of the National Supercomputing Jinan Center (hereinafter referred to as "Jinan Supercomputing") to thousands of industries.

Jinan Supercomputer was established on 20 1 1. It is one of the three petascale supercomputing centers in China, and its system comprehensive level is in the advanced ranks in the world today. Shandong Unicom's intelligent optical network provides a powerful capacity for Jinan Supercomputer, connecting scientific research units and Supercomputer Center, breaking the bottleneck of the distance limit between scientific research units and Supercomputer Center, and fully releasing the surging computing power, which has provided services for more than 400 units. In addition, Jinan Supercomputer relies on Shandong Unicom's smart cloud city network to realize real-time aggregation of weather data in the whole province and build an ensemble numerical weather forecasting platform to provide technical support for weather forecasting and accurate forecasting of disastrous, critical and turning major weather in Shandong Province.

During the Tenth Five-Year Plan period, the position of industrial digitalization as the main engine of digital economy will be continuously consolidated. As a key new infrastructure for industrial digital transformation, all-optical computing network will escort the digital economy with high quality. Based on all-optical network, artificial intelligence, big data and other cutting-edge technologies, Shandong Unicom will further build surging computing power and strong transmission capacity, continue to provide strong business support for the party, government, army, finance, medical education and other industries, and work together for a win-win digital future.
