Keynote Speech at Huawei Developer Conference: Full-link network acceleration, full-scenario speed experience

Hello everyone! What I want to introduce today is a full-link network acceleration solution. In modern society, people cannot do without the Internet. They use the subway to watch short videos, play games at noon, and watch online videos at night. However, we often encounter problems such as the short video cannot be turned around, the download of game resources is slow, and the video freezes.

Full-link network acceleration can help applications overcome network pain points. A network request goes from the wireless network to the operator's backbone network, then to the Internet public network, and finally to the data center or server. Each process faces many challenges, such as weak wireless network signals and many interference sources; insufficient bandwidth and congestion of the access network; DNS hijacking of the backbone network; in the context of cross-operator and cross-ocean data exchange, Unreasonable routing scheduling due to differences in regional network quality, etc.

After the full-link network acceleration capability is opened, the wireless transmission service as an atomic capability can enhance communication and combat network interference. Network Kit a one-time access to the full-link acceleration solution, helping network acceleration in scenarios such as content loading, file transfer, instant messaging, and multimedia. WiseWAN global boutique network is also under construction.

How can short video applications overcome unstable networks on the move?

In weak coverage areas of mobile networks, video applications often experience loading and freezing. This is what we often call signal black holes. This year, the wireless transmission service introduced AI signal prediction capabilities, so that streaming media no longer stalls. As shown in the figure below, if a car is driving on a certain path, the video will freeze when it passes through a weak signal area before integration. After integration, under the support of network QoE (user perception) changes, fixed routes, and AI machine learning, it can be weakened. Timely feedback of network predictions, and cache streaming media in advance.

How can real-time applications combat complex interference network environments?

Network latency not only affects the user experience, but also affects the application's advertising revenue. Data from Huawei's paid display service shows that for every 100ms of slow ad request, the click-through rate will drop by 3%-5%. Application integration Network Kit can obtain the network gain of the whole link.

In instant messaging scenarios, help applications for key services are delivered immediately. One: Small message congestion algorithm. Through packet loss and bandwidth detection, redundant packets are adaptively added in weak network scenarios to reduce delay and increase message arrival rate. Second: Intelligent heartbeat algorithm. In view of the current state of changeable mobile networks and applications, it can flexibly identify fake links, ensure link stability, and reduce heartbeat frequency. Third: Customize the priority of data packets to ensure that key services can be sent first under network congestion.

Multiple instant communication scenarios such as key game messages, social chats, conference control commands, and video barrage are applicable. for example! After the messaging application LinkNow integrates the Network Kit , the network request latency of the IM message sending scenario is reduced by 18%.

In the file transfer scene, help speed up the game resource pack. When playing a well-made game, you need to download game resources such as characters, maps, and props. There will be patch upgrades in the follow-up. These all directly affect the user's gaming experience. Network Kit uses Huawei's self-developed QUIC protocol and large file congestion algorithm to improve throughput; uses AI intelligent fragmentation algorithm, multi-threading, resumable transmission and other key technologies to improve bandwidth utilization. After the integration of Network Kit in the game "Douro Land" under Sanqi Mutual Entertainment, the download performance of the game resource pack has increased by 40%.

Does the page load within seconds with low latency?

Network Kit Another major capability is low-latency content loading. According to data from the Huawei App Market, there is no response when clicking on the page for 3 seconds, and 40% of users will opt out. So the success rate of page loading is very important.

Network Kit does DNS prefetching for the problem of unreasonable Internet DNS allocation, and the average delay is less than 20 milliseconds. In a weak network environment, improve network sensitivity, adjust dynamic network parameters, and make the network environment adaptive. Predict business behavior based on AI and build links in advance, so that short link costs can achieve the effect of long links. This capability is suitable for application scenarios such as account login, order information query, homepage resource query and loading. After the integration of the Huawei account and the Huawei member center, the average latency of business requests has been reduced by 22%-32%.

How to play multimedia applications in high-definition network congestion scenarios without stuttering?

In scenes such as on-demand video, live broadcast, and real-time audio and video, I believe you will often encounter situations where half of the broadcast suddenly freezes for more than 5 seconds. Data shows that 5% of users will exit the page directly at this time. In order to improve user experience, we use Huawei's self-developed QUIC protocol, self-developed multimedia congestion control algorithms, and AI intelligent dynamic adjustment to adjust network parameters in different network environments. At present, the demo developed by us and Huawei Video will soon be open, and we are committed to creating smooth multimedia.

Finally, I want to briefly summarize the acceleration capabilities of the full-link network: First, we have the atomic capability wireless transmission services. Developers can deeply adapt, such as AI signal prediction ability, predict the time when the network enters the stagnant area through accurate information; multi-network collaboration, flexible call interface, service games, online courses, and instant call scenarios.

Second, Network Kit easy to integrate to achieve full link acceleration . Open content loading, file transfer, instant messaging, multimedia and other scene capabilities, integrate the atomic capabilities of wireless transmission services, and achieve end-to-end acceleration after integration.
Simplicity is the ultimate complexity. We provide developers with the easiest way to access wireless transmission services and Network Kit, using Huawei's powerful and complex algorithms and huge cloud deployment. Here, developers can experience the best full-link network acceleration service. The above is my introduction, thank you all!
