IP TTL filter digital design, implemented in VHDL.
-
This project implements an IP TTL filter in hardware. If an IPV4
packet is identified, the DUT checks its TTL field. Based on previous values of TTL in former packets,
the machine decides if the packet is spoofed or not. The main page
of this
project.;
-
This page shows a simple test with multiple frames. Some are UDP and some are ARP. The wave shows that the ARP packets
are ignored (drop count increment). For each packet, identified as IPV4, learning and the check for spoof is
exercised.
