What protocols are used in Zoom?

Zoom employs a combination of network protocols to ensure efficient and reliable communication during meetings. The primary protocols used include:

1. User Datagram Protocol (UDP):

   • Purpose: Facilitates low-latency transmission of audio and video data.
   • Usage: Preferred for real-time media streaming to maintain high-quality communication.

2. Transmission Control Protocol (TCP):

   • Purpose: Ensures reliable data transmission by establishing a connection between sender and receiver.
   • Usage: Used when UDP is unavailable or when a more reliable connection is necessary.

3. Secure Sockets Layer (SSL):

   • Purpose: Provides encryption for data in transit, ensuring secure communication.
   • Usage: Utilized for signaling and control messages to protect user data.

4. Hypertext Transfer Protocol (HTTP):

   • Purpose: Facilitates communication between clients and servers.
   • Usage: Employed for web-based interactions, such as accessing Zoom's web portal.

5. WebSocket Protocol:

   • Purpose: Enables full-duplex communication channels over a single TCP connection.
   • Usage: Used for real-time messaging and notifications within the Zoom application.

By leveraging these protocols, Zoom ensures efficient, reliable, and secure communication for its users.
