UDP will be a good choice:
✅ If you have an app that needs to exchange data with several hosts as a time;
✅ If your application doesn’t rely on data being handled in a specific order in real time;
✅ If the speed of communication is desirable and error correction isn’t crucial;
✅ If you want to send a one-way notification about some activity and don’t expect any response, etc
The differences between TCP and UDP
So, now we’ll compare TCP and UDP protocol capabilities and see when using UDP can be more beneficial.
No connection setup. UDP is a connectionless protocol. This means it doesn’t have high overhead requirements which are characteristic of TCP. Since UDP does not use handshaking signals, delays caused by connection setup can also be avoided. These lower delays make UDP an appealing choice for delay-sensitive applications like audio and video.
Speed. UDP does not need to retransmit lost packets, it is frequently used for live broadcasts and online games.
Topological diversity. UDP can be multicasted to multiple hosts, in other words, with UDP you can establish one-to-one and one-to-many communications, while TCP only supports one-to-one connections.
Working in a multi-user environment. Сompared to UDP, TCP uses significantly more operating system resources, and, as a result, UDP is more commonly used in the environments where one server has to work with many clients at a time.
Lower bandwidth overhead. UDP consumes less network bandwidth, as its headers are only eight bytes long, while TCP messages have 20-byte headers.
Conclusion
UDP is considered to be the optimal transport protocol for applications aimed at fast data exchange. Serial to UDP Converter by Electronic Team lets you share COM-based devices over LAN and the Internet in the quickest and safest possible way. The solution will help you not only create an unlimited number of virtual COM ports but also give you the possibility to redirect serial port data to UDP and connect to it from any remote location.
