 | Found answer using chatgpt: Zoom uses a combination of both TCP (Transmission Control Protocol) and UDP (User Datagram Protocol). TCP is a reliable, stream-oriented protocol that establishes a secure connection between two devices and ensures that data is transmitted in the correct order and without errors. Zoom uses TCP to establish connections between clients and to transmit control messages, such as session setup and tear down, and to negotiate media properties. UDP, on the other hand, is an unreliable, datagram-oriented protocol that is used for transmitting real-time media such as audio and video. The use of UDP allows Zoom to transmit media quickly and with minimal latency, which is important for real-time communications. However, the trade-off for this speed is that some packets may be lost during transmission, which is acceptable for real-time media. In summary, Zoom uses TCP for control messages and UDP for transmitting real-time media to provide the best combination of reliability and performance for its users. Expand full comment |
