I. Introduction of WebSockets

in a literal sense, a handshake can be defined as two people holding and shaking hands, symbolizing greetings, congratulations, consents or goodbyes. in Computer science, a handshake is the process of ensuring that the server synchronizes with the client. Handshake is the basic concept of the Web socket protocol.

Shows the server handshake with various clients:

Web Sockets-Definitions

A web socket is defined as two-way communication between a server and a client, which means that both parties communicate and exchange data simultaneously.

the key point of Web sockets is true Concurrency and the Performance Optimization , resulting in a more sensitive and richer Web application.

description of the Web socket protocol

the protocol defines full-duplex communication from the beginning. Web sockets take a big step forward by bringing desktop-rich features into the Web browser. It represents an evolution that has been around for a long time in client/server Web technology.

The main features of the network sockets are as follows:

• The Web sockets protocol is being standardized, which means that with the help of this protocol, real-time communication between the Web server and the client is possible.

• Web sockets are being transformed into cross-platform standards for real-time communication between clients and servers.

• This standard allows for new applications. The business of real-time Web applications can speed up with this technology.

• The biggest advantage of a WEB socket is that it provides two-way communication (full duplex) through a single TCP connection.

HTTP has its own set of patterns, such as HTTP and HTTPS. the Web socket protocol also has a similar pattern defined in its URL pattern.

Browser Support

the latest specification for the WEB socket protocol is defined as RFC 6455 -A proposed standard.

RFC 6455 supported by various browsers such as Internet Explorer,mozilla Firefox,google Chrome,safari and opera.
