    老师,这个和之前的medooze-server-node 区别是什么啊

    作者回复: medooze demo属于应用层，medooze-server-node是基础库，medooze demo 使用 meddoze-server-node 实现多人通信。

    老师好，咱们搭建的medooze的demo能承担多少用户的负载？另外，sfu架构图有个别单词拼写错误，白璧微瑕^^

    作者回复: 单台500人，主要还和你的带宽有很大关系。SFU架构图我更新一下，抱歉！抱歉！

    不懂nodejs，大致看了下，应该是participant.on('stream' 这边，但是stream怎么触发就不知道了
