Note that we’ve got some connection tracking in packetnet-connections repo. It’s tcp specific now but overall the library is intended for tracking persistent connections and this sounds like it’s a little related.

You can possibly use more such as the size of the payload as it should always be 32-bit aligned going by the RFC. Also CC + length of length of the CSRC section. There's no certain way, but that is also the case for the other packets such as DHCP and WOL. — You are receiving this because you are subscribed to this thread.
