传输层上的UDP作为TCP／IP协议族中最重要的协议之一,扮演了重要的角色,虽然它并没有像TCP协议那样使用面向连接的方式,也不保证数据能够正确送达目的地,但是它的简洁灵活的特点也使它在实际应用中被广为使用。
UDP on the transport layer plays an important role as one of the most important protocols in the TCP / IP protocol suite. Although it does not use the connection-oriented approach like the TCP protocol, it does not guarantee that the data can be delivered to the destination correctly. But its concise and flexible features also make it widely used in practical applications.
