与TCP不同,UDP是一种无连接的、不可靠的、基于数据报的传输层通信协议。其主要特性包括: ●无连接:UDP不需要建立和维护连接,数据可以直接发送给接收方。 ●不可靠性:UDP不保证数据包的顺序、完整性和可靠性。数据包可能会丢失、重复或乱序。 ●基于数据报:每个UDP数据包都是独立传输的,具有明确的边界。 2. TCP...

UDP is best suited for transferring a steady flow of live data. This allows many users to access data easily and quickly, if not in perfect condition. A good example is playing an online game. UDP can keep the action moving in spite of potential errors or data loss. Here are a few ap...
