What is the Peer to Peer Network (Peer to Peer Network)?

Peer to peer network is a network in which the client acts as a service provider. Peer-to-peer networks will not have a central server.

WebRTC technology can be found in almost all modern browsers. It allows browsers to talk to one another instead of only to web servers.

Once connectivity has been established, browsers can exchange media streams, such as audio and video, file transfers, and messages via the fastest peer-to-peer possible.

The system can offer a variety of learning capabilities by using this peer-to-peer technology.

How do you create a peer-to-peer WebRTC connection?

Below are the steps to set up WebRTC P2P connections using the WebSocket messaging system -

1. Peers connect to Server through WebSocket.

ws://SERVER_NAME:5080/WebRTCAppEE/WebSocket

2. The client sends a JSON command to the server with a stream name parameter.

{

command : “join”,

streamId : “stream1”,

}

3. When the second peer joins the stream, the server sends the start JSON command to the first peer

{

command : “start”,

streamId : “stream1”,

}

4. The first peer create offer SDP and send it to the server by taking the Configuration command,

{

command : “takeConfiguration”,

streamId : “stream1”,

type : “offer”,

sdp : “${SDP_PARAMETER}”

}

5. The second peer creates answer SDP and sends it to the server by taking the Configuration command

{

command : “takeConfiguration”,

streamId : “stream1”,

type : “answer”,

sdp : “${SDP_PARAMETER}”

}

6. Each peer gets ice candidates several times and sends them to each other by taking Candidate commands through the server.

{

command : “takeCandidate”,

streamId : “stream1”,

label : “${CANDIDATE.SDP_MLINE_INDEX}”,

id : “${CANDIDATE.SDP_MID}”,

candidate : “${CANDIDATE.CANDIDATE}”

}

7. And Clients send leave JSON command to leave the room

{

command : “leave”,

streamId: “stream1”

}
