mediasoup v3 API 之二 Transport

WebRtcTransport

• Mediasoup 内部有多种 Transport 实现，其中 WebRtcTransport 的实现是基于 ICE Lite(精简版ICE)。
• WebRtcTransport 主要用来进行 client 端 与 mediasoup server 端 Router 进行通讯。
• ICE Lite: meaning that it does not initiate ICE connections but expects ICE Binding Requests from endpoints.
  • FULL ICE:是双方都要进行连通性检查，完成的走一遍流程。
  • Lite ICE: 在FULL ICE和Lite ICE互通时，只需要FULL ICE一方进行连通性检查， Lite一方只需回应response消息。这种模式对于部署在公网的设备比较常用。
