Applies for clients, servers, and proxies. See Section 11.1 of play.scale Support of scale operations for media playback. Applies only for servers. See Section 18.46 of . play.speed Support of the speed functionality for media delivery. Applies only for servers. See Section 18.50 of . setup.rtp.rtcp.mux Support of the RTP and RTCP multiplexing as discussed in Appendix C.1.6.4 of . Applies for both client and servers and any media caching proxy. setup.ice-d-m A feature tag representing the support of the ICE-based establishment of datagram media transport that is capable of transport establishment through NAT and firewalls. This feature tag applies to clients, servers, and proxies and indicates support of all the mandatory functions of this specification.

Proxy A policy where the proxy applies its own policies to determine which certificates are accepted. User A policy where the certificate is required to be forwarded down the proxy chain to the client, thus allowing the user to decided to accept or refuse a certificate.
