Hi,

There has been much talk about the usage of symmetric RTP. Also, draft-perkins-rtcweb-rtp-usage suggests that symmetric RTP is required.

However, the PeerConnection API currently only supports the establishment of uni-directional streams, so for a single two way communication one needs to create two separate uni-directional streams.

So, I assume that one requirement from RTCWEB to W3C will be to add support of the establishment of bi-directional streams to the PeerConnection API.

Regards,

Christer
