问题 Flow control is a function that prevents network congestion by ensuring that(71)do not overwhelm(72)with data. There are three commonly used methods for handling network congestion.(73)is used by network devices to temporarily store bursts of excess data in memory until they can be processed. (74)are used by receiving devices to help prevent their buffers from overflowing.(75)is a flow -control scheme in which the source device requires an acknowledgment from the destination after a certain number of packets have been transmitted.
选项 A、Buffer
B、Source-quench messages
C、Buffering
D、Windowing
答案D
解析 流量控制是一总通过保证发送端发送的数据不会湮没接收端设备来防止网络拥塞的方法。通常有三种常用方法来处理网络拥塞。缓冲是一种通过暂时保存处理不了的数据包的方法，等到数据包能够被处理。源抑至被接收端用来帮助防止它们的缓冲区溢出；窗口机制是一种流量控制机制，利用这种机制，发送端发送一定数量的报文需要对端接收到的报文进行确认。
