2013年6月5日 · To put it simply, WebSocket is a high level protocol (like HTTP itself) built on TCP (reliable transport layer, on per frame basis) that makes possible to build effective real-time application with JS Clients (previously Comet and long-polling techniques were used to pull updates from the Server before WebSockets were implemented.

Websocket is a application layer protocol while TCP is transport layer protocol. At transport layer, we usually have TCP and UDP protocol. Any message from application layer need to go through transport layer to be transmitted to other machine. Hence, websocket and tcp have a relationship to each other and can not be comparable.

2016年2月5日 · When you have to implement WebSocket from scratch using pure TCP/IP sockets you can plan to spend a few days until you have the basic protocol implementation working and can start to implement your own protocol on top of it (been there, done that, threw it away the moment a library was available which worked better than my own implementation).

WebSocket is a computer communications transport protocol (like TCP, HTTP 1.0, HTTP 1.1, HTTP 2.0, QUIC, WebRTC, etc.) Socket is an endpoint for sending and receiving data across the network (like Port number)

2015年8月3日 · On comparing speed of TCP/IP with WebSocket. A (RAW) TCP/IP connection will be faster than a WebSocket connection, for the reason that WebSocket is a layer on top of TCP/IP (thus is bound to be at most as fast as TCP/IP itself). It should be noted that your implementation of the protocol you use on top of TCP/IP may be worse than WebSockets.

2018年10月24日 · To send a specific data format like a webSocket frame over TCP, you just have to define the data format so that the reader of the stream knows where the frame starts and ends based on the format. One typical way is to send a set of data that includes a fixed size (known in advance) header format that includes a length of the total frame and ...

2020年6月20日 · In a nutshell, WebSockets are a thin transport layer built on top of a device’s TCP/IP stack. The intent is to provide what is essentially an as-close-to-raw-as-possible TCP communication layer to web application developers while adding a few abstractions to eliminate certain friction that would otherwise exist concerning the way the web works.

2012年10月23日 · As @oberstet correctly notes, WebSocket average latencies are basically equivalent to raw TCP or UDP, especially on a local network, so it should be fine for you development phase. The WebRTC Data Channel API is designed to be very similar to WebSockets (once the connection is established) so it should be fairly simple to integrate once …

2014年9月25日 · WebSocket is a protocol that can run over a TcpClient. WebSocket protocol defines the handshake and how to frame data. The best way of differentiate simple TCP connections and WebSocket connections is to have them listening in different ports, since you are going to use different protocols. It would be bad if you have them in the same port, it ...

2015年6月3日 · WebSocket: We have learned in the MQTT Essentials that MQTT is ideal for constrained devices and unreliable networks. It’s also perfect for sending messages with a very low overhead. It’s also perfect for sending messages with a very low overhead.
