本文探讨了TCP和UDP在网络拥堵期间的行为差异。TCP通过慢启动机制减少带宽使用，而UDP则可能占据TCP放弃的带宽，导致TCP饥饿现象。理解这种行为对于混合使用两种传输层协议的应用至关重要。

TCP incorporates mechanisms for reliability, flow control, and congestion avoidance. However, UDP is a lightweight protocol for faster and simpler data transmissions and does not include these features.
When there is a combination of TCP and UDP flows during a period of congestion, TCP tries to do its part by backing off on bandwidth called slow start. However, UDP with-out any flow control mechanisms continues, potentially using up the available bandwidth given up by TCP. This is known as TCP starvation/UDP dominance
It is not always possible to separate TCP- and UDP-based flows, but it is important to be aware of this behavior when mixing applications that use both transport layer protocols.
