copycat

Network/Transport Protocol Comparison Tool (UDP vs TCP, Custom vs TCP, IPv4 vs IPv6)

-------------

Important Files

• src/copycat: binary executable
• copycat.cfg: configuration file
• dest.txt: destination file each line should describe one destination with as followed IPv4: <unique-source-port> <public-address> <private-address> IPv6: <unique-source-port> <public-address4> <private-address4> <public-address6> <private-address6>

Encapsulation modes

UDP

Outer transport is UDP plus an optional layer 4.5 header (e.g.: SPUD, QUIC, PLUS) specified by raw bytes on client, size on server, both on peers.

Non-UDP

Outer transport is custom and specified by raw bytes, protocol number and size. Protocol number is used for socket filtering, except for TCP/UDP that use source ports.
