GetIceServerConfig - Amazon Kinesis Video Streams

GetIceServerConfig

Gets the Interactive Connectivity Establishment (ICE) server configuration information, including URIs, user name, and password which can be used to configure the WebRTC connection. The ICE component uses this configuration information to set up the WebRTC connection, including authenticating with the Traversal Using Relays around NAT (TURN) relay server.

TURN is a protocol that is used to improve the connectivity of peer-to-peer applications. By providing a cloud-based relay service, TURN ensures that a connection can be established even when one or more peers are incapable of a direct peer-to-peer connection. For more information, see A REST API For Access To TURN Services.

You can invoke this API to establish a fallback mechanism in case either of the peers is unable to establish a direct peer-to-peer connection over a signaling channel. You must specify the Amazon Resource Name (ARN) of your signaling channel in order to invoke this API.
