Creating a Linux Soft Switch

Environment: C on Linux Red Hat 7.3-2.4.18-3


The Linux Soft Switch allows a computer to work as a switch on layer 2. It is designed to switch packets based on MAC addresses and forward them to the proper outgoing network interface(s).

Note: With this version (1.0), Soft Switch can support up to four hosts connected to the Linux Soft Switch host. It means that the Soft Switch host has at least two NICs and the max is four NICs.

    Great work, I've dreamed about softswitch implemented on OS, But.. How about this problem.... For example if we try to apply some packet filters (i.e. port-blocking functions to your program), how it shoud be? Which functions of Libpcap/winpicap or just socket-base functions we should use? But the piece of code would be better!


  • Any photographs available, or any other help?
