Interactive Connectivity Establishment

<p>Interactive Connectivity Establishment (ICE) is a technique used in <a href="/facts/Computer_networking/3w5RM99p">computer networking</a> to find ways for two computers to talk to each other as directly as possible in <a href="/facts/Peer-to-peer/wCCdPb0H">peer-to-peer</a> networking. This is most commonly used for interactive media such as <a href="/facts/Voice_over_Internet_Protocol/5QGBbXYg">Voice over Internet Protocol</a> (VoIP), <a href="/facts/Peer-to-peer/wCCdPb0H">peer-to-peer</a> communications, video, and <a href="/facts/Instant_messaging/8lwwDyjK">instant messaging</a>. In such applications, communicating through a central server would be slow and expensive, but direct communication between client applications on the <a href="/facts/Internet/Xw1rVvJU">Internet</a> is very tricky due to <a href="/facts/Network_address_translator/nFweFNfN">network address translators</a> (NATs), <a href="/facts/Firewall_(computing)/Et2RkJaU">firewalls</a>, and other network barriers.
</p><p>ICE is developed by the <a href="/facts/Internet_Engineering_Task_Force/tIcCsFhX">Internet Engineering Task Force</a> MMUSIC working group and is published as RFC 8445, as of August 2018, and has obsolesced both RFC 5245 and RFC 4091.
