Cloud Scale telemetry begins with a handshake between the client and TCP/IP server on the switch, during which the client initiates the connection over the TCP socket. The client message is a 32-bit integer set to zero. The switch responds with a message...
Socket =>WkSocket); // Socket But the SktTCPConnect instance .Done output never returns true so I can't move forward with the next instructions. I made sure all the SktTCP functions have their Execute inputs intialised to False before that. In the built-in Ethernet IP port settings, ...

A three-way handshake is primarily used to create a TCP socket connection. It works when: A client node sends a SYN data packet over an IP network to a server on the same or an external network. The objective of this packet is to ask/infer if the server is open for new connections....

WebSocket是一种在单个TCP连接上进行全双工通信的网络协议。经过一次TCP握手就可以直接创建持久性连接,进而可实现服务端和客户端双向数据传输。Websocket建立一次连接后可以保持长时间的通信会话,链路复用,减少握手次数,从而能够满足业务上需要实时性和即时更新的功能。

// Notify all the users in the same room namespace.in(room).emit(‘newUser’, { users, username }) } catch (error) { console.log(error) } 注:我们更改了redis hash模式中的密钥(从socketId 变成了userName),这使得从web socket连接中获取用户信息更方便了。
