First, let’s discuss the overall idea—creating a convenient debugging TCP/IP protocol stack, level-ip. The specific operations can be divided such that we do not have to use the system’s socket interface for TCP communication. Now, this goal has been preliminarily achieved. One required component is tun/tap, which forwards data between the virtual device and the … Read more
