Websocket ping pong

7701

A ping or pong is just a regular frame, but it's a control frame. Pings have an opcode of 0x9, and pongs have an opcode of 0xA. When you get a ping, send back a pong with the exact same Payload Data as the ping (for pings and pongs, the max payload length is 125). You might also get a pong without ever sending a ping; ignore this if it happens.

Ping and Pong messages are the heartbeat of websockets. See Pings and Pongs "At any point after the handshake, either the client or the server can choose to send a ping to the other party. When the ping is received, the recipient must send back a pong as soon as possible. You can use this to make sure that the client is still connected, for example.

Currently defined opcodes for control frames include 0x8 (Close), 0x9 (Ping), and 0xA (Pong). Opcodes 0xB-0xF are reserved for further control frames yet to be defined.

A ping or pong is just a regular frame, but The application must read the connection to process close, ping and pong messages sent from the peer. If the application is not otherwise interested in messages from the peer, then the application should start a goroutine to read and discard messages from the peer. A simple example is: func readLoop(c *websocket.Conn) { for { if _, _, err := c.NextReader(); err != nil { c.Close() break Note: QWebSocket and QWebSocketServer handles ping requests internally, which means they automatically send back a pong response to the peer.

Ping must be called concurrently with Reader as it does not read from the connection but instead waits for a Reader call to read the pong. TCP Keepalives should suffice for most use cases. The Websocket protocol implements so called PING/PONG messages to keep Websockets alive, even behind proxies, firewalls and load-balancers. The server sends a PING message to the client through the Websocket, which then replies with PONG. If the client does not reply, the server closes the connection.

I found out a repo which includes the implements. You can WebSocket handles received Ping and Close messages automatically (as per the WebSocket Protocol) by replying with Pong and Close messages. If the listener receives Ping or Close messages, no mandatory actions from the listener are required. Note Before this example can work, the protocols WEBSOCKET and WEBSOCKETS must be specified as active services in the Services function in transaction SMICM. Note The program DEMO_APC_PING_PONG calls web pages and an ABAP program that uses APC and AMC to play ping pong.

websocket-sharp is developed with MonoDevelop.

WebSockets đã được phát triển với RTC, vì vậy khi tôi xem xét chức năng ping/pong, tôi cũng thấy cách đo độ trễ. Thực tế là các pong phải trả lại cùng một trọng tải hơn ping, làm cho nó rất thuận tiện để gửi một dấu thời gian, và sau đó tính toán độ trễ từ khách hàng đến máy chủ hoặc ngược lại câu.

ASP.net Core 3.1 is sending a Ping-Frame from the Server to the client in the defined interval from WebSocketOptions.KeepAliveIntervalproperty. So far everything works as expected. Ping and Pong messages are the heartbeat of websockets.
