java - 以下语句中的 "One hop per time interval "是什么意思？

Question

Write a program that simulates a computer network using discrete time.

The first packet on each router queue makes one hop per time interval. Each router has only a finite number of buffers. If a packet arrives and there is no room for it, it is discarded and not retransmitted. Instead, there is an end-to-end protocol, complete with timeouts and acknowledgement packets, that eventually regenerate the packet from the source router.

Plot the throughput of the network as a function of the end-to-end timeout interval, parameterized by error rate.

Answer 1

我过去曾接受过一些类似的作业。我最好的猜测是，“跳”表示从网络中的一个节点到另一个节点的传输，而“时间间隔”是任意的，本质上代表整个网络的更新周期。
