Have you ever wondered about having voice and video streaming without requiring any software or plug-ins?
There was a time when Flash and plug-ins were the only methods of real-time communication.
WebRTC (Web Real-Time Communication) technology delivers instant voice and video streaming without any plug-ins and Flash player.
Today, we at VideoEncrpyt will discuss the basics of Web real-time communication, APIs, Signaling, and Gateway.
What Is WebRTC?
What Is WebRTC API
There are three primary components of WebRTC. Here we will discuss the three components.
Peer Connection is the core of the WebRTC as it controls the Codec implementations, SDP negotiation, Bandwidth management, NAT Traversal, Packet loss, and Media transfer. It allows users to create connections with their participants without using any intermediate server. The participants are required to plug the media fetched from the media stream into the peer connection to create an audio or video feed.
Data Channel uses UDP-based streamings with the configuration of the SCTP (Stream Control Transmission Protocol) protocol. It helps in transferring of data and media data directly between the participants. Thus, data channels allow better delivery with reduced congestion in the network.
What is signaling?
WebRTC uses Peer Connection to communicate by using streaming data between browsers at two endpoints i.e. sender and receiver to exchange data to coordinate communication over a call. This mechanism to coordinate communicating and sending messages is known as signaling.
STUN (Session Traversal Utilities for NAT) allows WebRTC users to find out their own public IP address by making a request to a STUN server so that the user can connect through the possible direct route.
TURN (Traversal Using Relays around NAT) acts as a relay server when the communication fails. It helps the users in determining the routers on their local network when a direct connection is not possible due to firewall restrictions.
WebRTC provides a simple way to implement peer-to-peer communications between browsers and focus primarily on the media plane. WebRTC gateway helps you in connecting the conventional IP communications networks with the open ecosystem of the Internet.
It connects the Web and telecom world through signaling, networking, media, transcoding, and various functions. It can be delivered in the form of a turn-key appliance or a software-based solution that runs on the standard server.
WebRTC combines real-time interactivity and streaming right in the browser and is going to be a new front in the long war for delivering real-time communication without using any Flash player and plug-ins. We at VideoEncrypt are planning to deliver you an interactive and streaming platform based on WebRTC.
