In this article we will dwell a bit more on the WebRTC side.

在本文中，我们将更详细地讨论WebRTC方面。

WebRTC enables two way communication between multiple people, typically less than 1000. The cost of running WebRTC for a very large number of users is very high. The lag / latency is less, running in less than a second, can run in a few ms too.

WebRTC实现了多人之间的双向通信，通常少于1000人。对于非常大量的用户来说，运行WebRTC的成本非常高。延迟/延迟较低，运行时间少于一秒，也可以在几毫秒内运行。

One of the questions which people generally have in their mind around WebRTC is whether is it the only solution which enables such communication? The answer is no. It is possible to build custom solutions too. As per How Zoom’s web client avoids using WebRTC (DataChannel Update) — webrtcHacks, Zoom initially used Websockets and WebAssembly to transfer and decode media initially and later moved to WebRTC Datachannel as of 2019 but still doesn’t use the complete WebRTC stack. There are many other options too.

人们普遍对WebRTC有一个问题，那就是它是否是唯一能实现这种通信的解决方案？答案是否定的。也可以构建自定义解决方案。根据How Zoom’s web client avoids using WebRTC (DataChannel Update) — webrtcHacks，Zoom最初使用Websockets和WebAssembly来传输和解码媒体，后来在2019年转向WebRTC Datachannel，但仍未使用完整的WebRTC堆栈。还有许多其他选择。

However, using WebRTC has many advantages the most important ones being
