What protocol does WebSocket use?
The WebSocket protocol is an independent TCP-based protocol. Its only relationship to HTTP is that its handshake is interpreted by HTTP servers as an Upgrade request. By default the WebSocket protocol uses port 80 for regular WebSocket connections and port 443 for WebSocket connections tunneled over TLS [RFC2818].
Why you should not use WebSocket?
The WebSocket protocol offers a persistent connection to exchange messages. Avoid using WebSockets if only a small number of messages will be sent or if the messaging is very infrequent. Unless the client must quickly receive or act upon updates, maintaining the open connection may be an unnecessary waste of resources.
How is WebSocket different than HTTP?
WebSocket is an event-driven protocol, which means you can actually use it for truly realtime communication. Unlike HTTP, where you have to constantly request updates, with websockets, updates are sent immediately when they are available.
What is WebSocket and why it is important?
WebSocket is a two-way computer communication protocol over a single TCP. This is a common definition for it. Using WebSockets is a good way to handle high scale data transfers between server-clients. You can find many definitions like that on the simple Google (or Bing :)) search.
Are WebSockets safe?
WSS is secure, so it prevents things like man-in-the-middle attacks. A secure transport prevents many attacks from the start. In conclusion, WebSockets aren’t your standard socket implementation. WebSockets are versatile, the established connection is always open, and messages can be sent and received continuously.
How do WebSockets work?
A WebSocket is a persistent connection between a client and server. WebSockets provide a bidirectional, full-duplex communications channel that operates over HTTP through a single TCP/IP socket connection. At its core, the WebSocket protocol facilitates message passing between a client and server.
What are WebSockets good for?
WebSockets are ideal for providing real-time transport and communication between AV-over-IP devices. For example, the BSS DCP-555 Template-Based Conferencing Processor uses a WebSocket connection in parallel with a standard TCP connection to allow configuration of meeting rooms via a web browser interface.
Is WebSocket a stream-based or package-based protocol?
WebSocket is a message based protocol that does not specify a maximum message size in the RFC. This does not make it a streaming protocol until an implementation decides to deliver incomplete messages to the end application.
How is WebSocket different from TCP?
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.

What is a WebSocket API?
The WebSocket API (WebSockets) Jump to: The WebSocket API is an advanced technology that makes it possible to open a two-way interactive communication session between the user’s browser and a server. With this API, you can send messages to a server and receive event-driven responses without having to poll the server for a reply.
