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. Platform: |

Description: 选择重复 (Selective Repeat)
发送点连续发送数据包但对每个数据包都设有个一个计时器。
当在一定时间内没有受到某个数据包的ACK时，发送点只重新发送那个没有ACK的数据包
这个方法的缺点是接收点收到的数据包的顺序可能不是发送的数据包顺序。因此在数据包里必须含有顺序字符来帮助接受点来排序。-Select the duplicate (Selective Repeat) send data packets sent straight points but each packet has a one timer. When a certain period of time has not been the ACK packet is sent when there is no point just re-send that ACK packets disadvantages of this method is to receive points in the order received packets may not be the order of packets sent. Therefore, the data package must contain in order to help the character to accept the point of order. Platform: |
