Refer my Google Drive export diagram of the IPUtils :: Ping command implementation architecture:

  • [+] green box represents function pointer set
  • [+] yellow boxes are the important APIs/functions
  • [+] gray boxes are the standard external APIs (such as system calls and glibc library)
  • [+] pink/purple box(es) are the additional helper APIs (which are not as critical as those yellow ones)

* please note that I am not expanding deliberately ping6_run() and ping6_function_set since it is quite obvious that it has the same identical architecture as that of IPv4 implementation (i.e: ping4_run() and ping4_func_set).
