Referring to the content related to Web Sockets section

In the WebSockets approach, the amount of requests is much less than the polling approach. It is because the connection between the client and server is persistence. Once the connection is established, a request from either client-side or server-side is only sent when there is any update. For instance, a client sends a message to server when it wants to update something to server. The server also sends messages to clients only when it needs to notify the clients for data update. No other useless requests are sent during the connection. Therefore much less bandwidth is used. The following graph shows the WebSockets approach.
