\section{\label{results:general}General}
Parser for all protocols (udp,tcp,icmp,icmp6)

BMV2: more feature rich, but software only solution
NetFPGA: capabale of line speed Nat64, focused port on nat64

Both support EAMT as defined by RFC7757 \cite{rfc7757}.

\section{\label{Results:BMV2}BMV2}

Responds to icmp, icmp6
ndp \cite{rfc4861}
arp

test framework openvswitch

Fully functional host
Can compute checksums on its own.

focus on typical use cases of icmp, icmp6, the software implementation
supports translating echo request and echo reply messages, but does
not support all ICMP/ICMP6 translations that are defined in
RFC6145\cite{rfc6145}.

Stateful : no automatic removal

General result: limited NAT64 is working, however

  No Payload
  checksumming - requires controller

  Hash funktion in Arbeit

  No NDP, no ARP - focused on key factors of NAT64 translation,
  other features can be supported by controller
