What is Google's recommended network protocol for Google Meet traffic?

The recommended network protocol for Google Meet traffic is UDP. This is because UDP (User Datagram Protocol) is designed for fast and efficient data transmission, which is crucial for real-time applications such as video and voice communication. It allows for lower latency and faster delivery of packets since it doesn't require the establishment of a connection before transmitting data, nor does it have the overhead of ensuring that every packet is delivered and in the correct order, as TCP (Transmission Control Protocol) does. This makes UDP particularly suitable for applications like video conferencing, where maintaining real-time communication is more important than ensuring every single packet is received without loss.

In contrast, other protocols like TCP provide reliability and order but come at the cost of increased latency, which can negatively impact the quality of a video call. Protocols such as FTP (File Transfer Protocol) and HTTP/2 are not suitable for real-time communication due to their design focus on file transfer and web communication, respectively, rather than delivering continuous streams of audio and video. Thus, UDP is the ideal choice for Google Meet to ensure a smooth and responsive user experience.
