How to realize high stability and high concurrency of live video streaming transmission and viewing?

We talked about it in a blog post before , The existing live broadcasts are generally divided into two types , One is that the device end is single , But there are many types of terminals , Generally, it is mainly webcast , Including live entertainment 、 Teaching live broadcast, etc ; The other is that the number of channels at the device end is very large , And the type of terminal viewing fewer people , Generally, it focuses on the live monitoring of the security industry , Such as intelligent transportation 、 Smart construction site, etc . The high concurrency of webcast is more common among ordinary mobile phone or computer users .

Design the architecture of a webcast system , We must pay attention to the high stability of the system 、 High availability 、 Three features of low latency , For users who are enjoying webcast , Smooth viewing experience is an important standard to measure whether a platform is of high quality , Therefore, high concurrency processing can not be ignored . such as EasyDSS Such a video platform , When a TV station is occupying the channel for live broadcast , Or when a teacher gives lessons to students through open classes on the Internet , There will be a large influx of users in a certain period of time ,EasyDSS The live broadcast pressure that the platform has to bear will also follow , that EasyDSS How to solve this kind of high concurrency problem ？

EasyDSS The following solutions are available ：

1、 Improve hardware processing capability

The essence of this scheme is to add more sets of system servers , To alleviate the pressure in the house caused by a single server , but EasyDSS It is a video platform deployed by a single server , For users , Adding servers also increases the deployment budget ; Besides , When the server increases to a certain extent , Its traffic will also reach a bottleneck .

2、 use CDN Speed up

When we talk about sudden traffic, we always think of CDN,CDN And the technical support of cloud service providers has become the most important guarantee in the content communication level of the current live platform , At the same time, it also escorts its business expansion . since this year on , Whether it's EasyDSS still EasyGBS, Both have supported the addition of video channels CDN Streaming distribution function , Make content transfer faster 、 A more stable , It effectively avoids the link that the network may affect the speed and stability of video data transmission .

3、 Load balancing

We have explored the topic of EasyDSS、EasyGBS、EasyCVR And so on , For sudden high load 、 High concurrency live broadcast tasks , Load balancing is an advanced solution ,EasyDSS By configuring stream The function module realizes load balancing , According to different user needs , It can also achieve different forms of load balancing , Like vertical expansion or horizontal expansion 、 Hard load or soft load, etc .

So to sum up ,EasyDSS The best solution for the platform to handle high concurrency is through CDN+ Load balancing , It's not hard to see. , Solving the problem of high concurrency is an indispensable link in the development of live broadcast platform . If you want to know more about our load balancing , You can read this article ： Why should the streaming media platform achieve load balancing ？ What's the point ？ Of course, we also welcome you to try EasyDSS, Experience for yourself EasyDSS Processing capacity for different user needs .
