Какой кандидат от kurento используется для ReceiveCandidate в клиенте?

Question

I мксек # Icelink для разработки WebRTC, когда я послал JSON "операцию": "gatherCandidates" в kurento

Kurento ответить на многие кандидата на меня, как это ::

Он имеет оба TCP и UDP.

Мой Вопрос

1.Which кандидат использовать для ReceiveCandidate в клиенте. TCP или UDP, если использовать TCP, то используется host host tcptype активным или пассивным?

2.Op мой клиент получает всех кандидатов от kurento?

Thankyou FR вперед,

Answer 1

Во время установления соединения WebRTC, каждый узел посылает набор кандидатов ICE к удаленному узлу. Этими кандидатами могут быть UDP, TCP, srflx (STUN), хост или реле (TURN). Когда удаленный одноранговый узел получает кандидатов, он начинает проверять эти IP-адреса и порты, чтобы узнать, можно ли установить соединение. Вот почему каждый одноранговый узел отправляет несколько из них, поэтому у удаленного партнера больше шансов найти действительного кандидата.

Если вы хотите узнать, какая из пар-кандидатов используется, вы можете подписаться на NewCandidatePairSelectedEvent с вашего WebRTC.
