Pros & Cons of UDP vs TCP
Gain an understanding of the pros and cons of using UDP vs TCP for delivering large bandwidth video streams in order to
help inform decision-making about which protocol to build a service around
- TCP works on something called 'flow control principle' which means it won't transmit new data if previous packages haven't been fully transmitted.
- Thus, the pro of TCP protocol is that it's guaranteed all data packages will be delivered, and no part of the media stream will be lost.
- Another source notes that the use case is likely relevant. Streaming sports would be better for UDP as even a few second lag may make people miss a major game event, whereas for streaming where the quality including having no gaps is of higher priority, for example, streaming or downloading a video for quality playback, TCP may be better.
