Description: 基于UDP实现简单的可靠数据传输
由于数据是在不可靠的信道上传输的，因此数据在信道上传输时可能会发生比特错误，数据丢失。Rdt3.0及之前的版本都是停止—等待协议，它限制了网络底层硬件的能力。为克服这个问题引入了流水线技术，两个能恢复流水线中的错误的基本方法：第N个分组重发和选择性重复。综上，要实现差错编码，顺序号，计时器，分组确认，滑动窗口，拥塞控制。-simple UDP based on the reliable data transmission of data is not reliable transmission of the channel, therefore the data transmission channel may occur bit error, data loss. Rdt3.0 and earlier versions are stop-wait for the agreement, which limits the underlying network hardware capabilities. To overcome this problem the introduction of pipeline technology, both of which can restore pipeline error in the basic methods : section N to a re-issued and selective repeat. In sum, to achieve error coding, sequencing, the timer, a confirmation, sliding window, congestion control.
