javascript - Is my understanding of WebRTC protocol Correct? -

-

this how understand protocol...

  • user on browser media stream
  • generates own sdp (data on codecs, security, etc)
  • creates offer it
  • send offer server via signalling method (websocket)
  • signalling server, looks offer , redirect client
  • client 2's browser gets offer sdp , in turn generate own offer own sdp , send server
  • server redirect client 2's offer client 1. both know each other specs.

meanwhile, however...

  • as whichever client sends offer sdp start contact ice (stun) server(s) possible reachable path them via correct publicip:port:protocol combo, send client via signalling server.

client 2 generates answer (using createanswer), not offer. main difference answer subset of capabilities (like codecs) contained in offer.

otherwise sounds good.
