SHENZHEN, China, Jan. 18, 2023 /PRNewswire＝KYODO JBN/ --

On January 17, 2023, the six finalists of the Franz Edelman Competition were

announced. Among them is Huawei Cloud, which stands out from the competition

with its pioneering cloud resource scheduling technology and excellent market

performance. The Franz Edelman Award is presented annually by the Institute for

Operations Research and the Management Sciences (INFORMS) to recognize

achievements in the management sciences. Huawei Cloud is the first cloud

computing company to be shortlisted for scheduling technology in the past 50

years.

How to maximize cloud resource utilization without compromising service quality

remains a critical but challenging issue for the cloud industry. Huawei Cloud's

industry-leading cloud resource scheduling technology provides a solution that

increases media network resource utilization by over 30% with its innovative

algorithms. The improved quality of service (QoS) has translated into ten-fold

livestreaming business growth over the past two years.

Top scientists and innovative algorithms to solve industry problems

Huawei Cloud assigned 39 scientists across 16 research centers both inside and

outside of China to conduct research on cloud resource scheduling. Yuan

Xiaoming, Chief Scientist of the Huawei Cloud Algorithm Innovation Lab,

collaborated with experts in the livestreaming field to work on maximizing

resource utilization and ensuring service quality under billing by 95th

percentile bandwidth. Scientists developed algorithms for offline and online

problems, respectively. During the problem-solving process, they encountered

two difficulties:

First, due to the non-convex and non-smooth cost function in the mathematical

model, minimizing the cost under billing by 95th percentile bandwidth is

NP-hard. Second, Huawei Cloud Live involves more than 2,800 edge nodes. This

means that there are 120 billion binary and continuous variables in the

corresponding mathematical models.

In addition, it is difficult to develop an algorithm that is capable of

providing an accurate scheduling scheme within milliseconds in real-world media

network scheduling scenarios.

To accurately describe these problems, experts built a series of mathematical

programming models, which provide a paradigm for further research. Experts also

performed in-depth analysis on the structure and mathematical characteristics

of the models. They split problems into subproblems, for which algorithms that

combine easy problem-solving and implementation with high efficiency and

stability were developed. Numerical experiment results show that these

algorithms improve media network utilization by more than 30%, and also provide

better QoS indicators such as higher stream pull success rate, shorter frame

freezing in 100 seconds, and less time needed before playing the first frame.

Huawei Cloud also drives many other aspects of scheduling to new heights, such

as through its industry-leading shortest-path MKSP algorithm and its

collaboration with the Huawei Backbone Network (an industry-unique feature) and

advanced cloud services. The scheduling-related research has yielded 30 patents

and 6 research papers.

Huawei Cloud's media network scheduling system fuels the growth of livestreaming

Huawei Cloud's media network scheduling system, which resolves issues that have

long plagued the industry, has been adopted by China's top livestreaming

platforms such as Douyu and Huya. Huawei Cloud developed a network traffic

model and scheduling scheme, which accommodate traffic fluctuations, to ensure

the smooth livestreaming of key events. With Huawei Cloud, more than 60

international sports events have been successfully broadcast live. Huawei

Cloud's livestreaming solution features industry-leading QoS, which includes

100% stream pull success rate, end-to-end latency of 2 to 3 seconds, latency of

less than 800 milliseconds by Low Latency Live, and live video starting

playback in seconds without frame freezing. The quantity of media resources

provided by Huawei Cloud for major livestreaming platforms in China has grown

10 times in the past two years.

Adhering to the strategy of Everything as a Service, Huawei Cloud will harness

its cutting-edge scheduling technology to create more value for industries such

as energy, transportation, logistics, and retail.
