The main difference between Server message and P2P message is the delay and the presence of a server in the middle.
|In P2P messaging, the messages are sent through the WebRTC Data Channel (through the peer connection).||In Server messaging, messages are sent through the Signalling Server. |
|When you send a message to many peers through P2P messaging, you end up sending one-on-one messages to multiple people. ||The message is sent to the server which then broadcasts it to other peers. |
|P2P will be faster, but might end up bloating the sending peer.||Relayed might add some latency, but is lighter on the sending peer.|
|P2P Messaging uses the RTCDataChannel where all data is secured with Datagram Transport Layer Security (DTLS).||Server messaging is useful when there are a lot of peers ( i.e.) to balance load. In the future, this would allow features such as asynchronous communication (e.g. store the message and send it when the user gets online).|
