Answer from AI
The TCP (Transmission Control Protocol) transport layer protocol is used to ensure WebSocket communication. TCP provides reliable, ordered, and verified data transfer between the client and server, which is necessary to maintain a persistent, bidirectional WebSocket connection.
WebSocket establishes a connection over TCP, starting with an HTTP request for connection setup (handshake), after which the protocol switches to WebSocket, and further data transfer occurs over the TCP connection.
