4·This process is repeated until the datagram can be delivered to its destination host.

这个过程将反复进行，直到能够将数据报传递到其目的地主机为止。

5·The protocol informsIP at the destination host whether to pass the packet up to TCP or UDP.

该协议通知目标主机的IP协议程序，究竟是把这个数据包传递给TCP协议还是传递给UDP协议。

6·At the destination host, the packet is passed up to UDP and delivered to the destination port.

7·Along its way, the datagram will get sent to Gateway G, which will in turn forward it to its destination host.

在传输过程中，数据报将被发送到网关 G，而网关 G 又会将它转发到目的地主机。

8·Even if they travel through multiple routers packets are only reassembled when they reach the destination host.

即使它们穿越了多个路径中的多个路由器，三个小数据包也只有在全部到达目标主机时才重新装配。

9·As discussed above, when Host a wants to establish a TCP connection to destination Host d, it sends a TCP segment with the SYN flag set first.
