This question seems to be easy to build. In fact, the maximum flow with bare minimum cost will inevitably Time Out, And the zkw billing flow will also time out. Therefore, you must understand the meaning of the question. The question must be better than the current solution, and the question should be the best. According to the theorem, a fee flow is a sufficient condition for the minimum cost flow, that is, the residual network of the fee flow has no

Using ethstatus in UbuntuServer can monitor the bandwidth usage of network adapters in real time. Run the sudoapt-getinstallethstatus command to install the software and use the ethstatus-ieth0 to view the eth0 Nic. The following figure shows the RX and TX rates of the current Nic. The unit is Byte. In addition, you can use vnstat. Install: sudoapt-getinst to collect statistics on the total traffic. Using
