What type of transmission method is suitable for LANs where traffic is under control and interruptions are not likely?

The best transmission method for a Local Area Network (LAN) where traffic is controlled and interruptions are unlikely is UDP, or User Datagram Protocol. UDP is a connectionless protocol that allows for fast transmission of data without the need for establishing a connection before sending packets. This characteristic makes it particularly suitable for real-time applications, such as audio and video streaming, where timely delivery is critical, and some data loss can be tolerated.

In environments where traffic is controlled and stable, the benefits of UDP come to the forefront. Since UDP does not perform error-checking or ensure packet delivery, it minimizes latency and overhead, making it ideal for applications that require quick, efficient transmission of packets without the delay of acknowledgments or retransmissions. This efficiency is especially relevant in audio networking contexts, such as those utilizing Dante technology, where low latency and timely delivery of audio streams are paramount for maintaining sound quality and synchronization.

Conversely, protocols like TCP (Transmission Control Protocol) are more suited for scenarios where reliability and error correction are necessary, as it establishes a connection and ensures that all packets are received in the correct order. Choices like SMTP (Simple Mail Transfer Protocol) and IMAP (Internet Message Access Protocol) are specifically designed for email transmission and retrieval, and are not
