TheĬlient and server can then exchange data messages whose framesĬontain compressed data in the payload data portion. PMCE and determine the parameters required to configure theĬompression algorithm during the WebSocket opening handshake. WebSocket client and a peer WebSocket server negotiate the use of a The WebSocket Protocol specified in Section 9 of.

This document is a product of the Internet Engineering Task Force This is an Internet Standards Track document. Thisĭocument also specifies one specific compression extension using the Negotiation and the payload transformation algorithm in detail. In a document defining the extension by specifying the parameter Each compression algorithm has to be defined General method for applying a compression algorithm to the contents Of WebSocket data messages on a per-message basis using parameters AnĮxtension based on this framework compresses the payload data portion That add compression functionality to the WebSocket Protocol. This document defines a framework for creating WebSocket extensions There are many known compression/ decompression ALGORITHMaSn,d the search for better ones has become commercially important since most new communications technologies (such as digital television) can only work with effective data compression.Internet Engineering Task Force (IETF) T. In an uncompressed file, it’s a minor problem, but in a compressed file, it can be a catastrophe of considerable dimension. All it takes is to lose one bit, one electronic signal, from a compressed file and that file is destroyed. Keep in mind that even when you are archiving files you never want to compress your original and only file. Since there’s less data, it takes less time to transfer them. And some modems and communications software can compress the data they send back and forth to one another. Some programs have the ability to compress data that’s being held in memory, allowing the computer to keep more data in memory and thus spend less time retrieving data from the disk. Using a compression utility, you can compress files stored on disk so that they take up less disk space and leave more space for other files. When you compress computerized information, you make it smaller (taking up less space on the disk), meaning that less data is needed to represent exactly the same information.
