What is RTCIceCandidate?
The RTCIceCandidate interface—part of the WebRTC API—represents a candidate Interactive Connectivity Establishment (ICE) configuration which may be used to establish an RTCPeerConnection . An ICE candidate describes the protocols and routing needed for WebRTC to be able to communicate with a remote device.
What is sdpMid?
The read-only property sdpMid on the RTCIceCandidate interface returns a string specifying the media stream identification tag of the media component with which the candidate is associated. This ID uniquely identifies a given stream for the component with which the candidate is associated.
What is WebRTC ICE?
ICE stands for Interactive Connectivity Establishment. It is a standard method of NAT traversal used in WebRTC. It is defined in IETF RFC 5245. ICE deals with the process of connecting media through NATs by conducting connectivity checks.
How does ICE protocol work?
This protocol is called Interactive Connectivity Establishment (ICE). ICE makes use of the Session Traversal Utilities for NAT (STUN) protocol and its extension, Traversal Using Relay NAT (TURN). ICE can be used by any protocol utilizing the offer/answer model, such as the Session Initiation Protocol (SIP).
What is WebRTC used for?
WebRTC (Web Real-Time Communications) is an open source project that enables real-time voice, text and video communications capabilities between web browsers and devices. WebRTC provides software developers with application programming interfaces (APIs) written in JavaScript.
What is STUN WebRTC?
STUN stands for Session Traversal Utilities for NAT. It is a standard method of NAT traversal used in WebRTC. It is defined in IETF RFC 5389. It is one of two NAT traversal servers that are used in WebRTC (the other one is TURN).
What is ICE firewall?
ICE defines a standardized method for SIP-enabled clients (or clients based on other multimedia session protocols) to determine what type of NAT firewall(s) exist between clients and determine a set of IP addresses by which clients can establish contact.
What is TURN STUN?
TURN is an extension of STUN, and as such, TURN servers also typically listen on port 3478. However, TURN provides STUN capability and more. TURN is a protocol for relaying media traffic through a service when a direct connection between two endpoints is not possible.
Should I disable WebRTC?
If you use a proxy, then WebRTC will be able to determine your real IP address for the proxy or IP address of the VPN server if you use the VPN + proxy chain. WebRTC also determines your real IP address using Tor network. The best solution is to disable WebRTC technology if you do not use it.
Do I need a STUN server?
Most clients will be behind NAT, so you need STUN to get the clients public IP. But if both your clients were not behind NAT, then you wouldn’t need STUN. More generally, no, a STUN server is not strictly required. I know this because I successfully connected 2 WebRTC peers without a stun server.
What is the purpose of STUN server?
STUN provides the mechanism to communicate with users behind a network address translation (NAT) firewall, which keeps their IP addresses private within the local network (LAN). The initiating party sends a request to the STUN server, which maintains the IP addresses of the phone or computer (for video).
What is SIP ICE?
What app is STUN?
STUN is a tool for communications protocols to detect and traverse network address translators that are located in the path between two endpoints of communication.
Who owns RTC?
RTC was founded in 1950 by Walter Nathan. Walter’s son, Richard Nathan, with 40 years of experience, now leads the family-owned business.
What is the rtcicecandidate interface?
The RTCIceCandidate interface—part of the WebRTC API —represents a candidate Interactive Connectivity Establishment ( ICE) configuration which may be used to establish an RTCPeerConnection. An ICE candidate describes the protocols and routing needed for WebRTC to be able to communicate with a remote device.
What is the rtcicecandidate () constructor?
The RTCIceCandidate () constructor creates and returns a new RTCIceCandidate object, which can be configured to represent a single ICE candidate. An optional object that can be provided to configure the candidate. The object has the following properties:
What is the rtcicecandidate string for?
This string is empty ( “”) if the RTCIceCandidate is an “end of candidates” indicator. A string which indicates whether the candidate is an RTP or an RTCP candidate; its value is either rtp or rtcp, and is derived from the “component-id” field in the candidate a-line string.
