用于webrtc的Java信令服务器(Java signaling server for webrtc)

 在下面的文章中： WebRTC食谱文章 
 
 解释了如何实现java信令服务器。 
 
 据说： 
 
 
 
 因此，两个客户端交换必要的数据（包括网络细节），然后建立直接的点对点连接。 连接建立后，对等端不再使用服务器。 
 
 
 但是看代码服务器仍然需要将通信中继到所有客户端（sendToAll-method）。 
 
 任何人都可以向我解释如何使用这样的代码进行直接的点对点通信吗？ 我仍然无法弄清楚2个（或更多）客户端如何与p2p进行通信。 

In the following article: WebRTC Cookbook Article
 
is explained how a java signaling server can be implemented.
 
It is said that:
 
 
 
So both clients exchange the necessary data (including network details) and then establish direct peer-to-peer connection. After the connection is established, peers don't use the server anymore.
 
 
But looking at the code the server is still needed to relay the communication to all clients (sendToAll-method).
 
Can anyone explain me how a direct peer-to-peer communication is possible with such a code? I still can't figure out how 2 (or more) clients can communicate p2p.
