Behind this is the digital construction of Alibaba’s economy to support the whole society’s Double 11, support such a large volume of nunchucks. Follow the editor to understand the latest and fastest core technologies of this year’s Singles’ Day.

Taobao live, create the global content of the technical peak of the electric shopping mall

“This year’s Tmall Double 11 is the most special year.” Jiang Fan, president of Taobao’s Tmall, said that as the world’s biggest post-covid-19 spending season, many merchants have stronger expectations for Singles’ Day. From October 21, Taobao live launched the pre-sale of this year’s Double 11, Taobao live has become the first choice of merchants in content marketing media. From the technical point of view, how can tao live broadcast technology system support online high concurrency, but also to ensure real-time interaction between anchors and users, the accuracy of transactions?

Tao developed global real-time transmission network – GRTN

GRTN is a new generation of multimedia transmission network, which realizes intelligent scheduling of traffic and computing power. Through big data calculation, it gathers DATA of CDN and client, and adopts automatic control theory to automatically control CDN bandwidth. At the same time, the content production of Taobao live broadcast realizes the intelligent scheduling ability of terminal and cloud. According to the performance of terminal and the capacity of cloud, the production location can be dynamically adjusted to reduce resource costs and ensure the stability of the system.

Compared with the 3~5 seconds delay of other live broadcast platforms, GRTN allows the delay of Taobao live broadcast to be controlled within 1 second. This year’s Double 11 is the first large-scale application of GRTN in Taobao live e-commerce. The extremely low interaction delay brings the qualitative improvement of interactive experience. In order to achieve tens of millions of online concurrency, still can let the anchor confidently shout out “123, open robbery!”

At the same time, based on the dynamic capacity expansion characteristics of GRTN, it ensures that the cost decreases by 30% simultaneously while the consumption of live broadcast bandwidth increases rapidly.

End-to-end intelligent power livestreaming innovative gameplay

With the rapid development of mobile side computing power, the interactive playability and understanding accuracy of live broadcast content are greatly improved. Relying on MNN end-to-end and side inference engine developed by Tao department and open source, Taobao live broadcast room launched a challenge of “voice guess price”. Audiences can also realize voice interaction in the live broadcast room, and they can respond to the task of guessing product price sent by anchors by moving their mouths.

The audiences of Taobao live broadcast are all over the country, and their accents vary greatly, which puts forward high requirements for recognition algorithms. At the same time, if Siri and other cloud-based voice recognition technologies are used, the recognition delay of strong interaction of live broadcast scenes cannot be met. In the face of millions or tens of millions of viewers, it will be worse, and the end-to-end recognition engine will also face great challenges. In order to realize real-time voice interaction, this live broadcast of Taobao adopted a new mobile terminal voice recognition scheme. Based on the new network structure, the speech recognition error rate in difficult scenes is reduced by nearly 30% due to problems such as fast speech speed and strong accent. At the same time, MNN, the inference engine, has also focused on the optimization of the speech recognition model, achieving the completion of the speech interaction process within 50 milliseconds, which is 20 times faster than traditional speech recognition.

The platform and merchants jointly complete digital intelligence operation

Digital new infrastructure achievements in the history of the largest merchant full link pressure test

In the past, due to the “water level difference” between the platform and the business IT infrastructure, IT was difficult for the platform to help the business to transform and upgrade the system.
