呼叫流程

关键几点：

1、调用new RTCPeerConnection(configuration ) 建立RTCPeerConnection对象

2、configuration has the information to find and access the servers used by ICE（Interactive Connectivity Establishment (ICE) IETF）. There may be multiple servers of each type and any TURN server also acts as a STUN server.

3、An RTCCertificate can be persisted in [INDEXEDDB] and reused. Persistence and reuse also avoids the cost of key generation.

4、createOffer和createAnswer(SDP)

5、Datagram Transport Layer Security (DTLS)

6、RTCDataChannel和RTCDataChannelEvent

7、Javascript API[JSEP]: IETF 连接建立API

8、 bindings about Web IDL[WEBIDL] correspond to particular constructs in Java 5[JLS3].
