Several transition mechanisms exist that include  translating IPv6 packets into IPv4 packets,  thus enabling the coexistence and interoperability of both protocols.  3 years ago   This thesis describes an implementation of the translation mechanism  NAT64, implemented in P4. Using the P4 programming language  3 years ago a software emulated switch was created that translates IPv4 to IPv6 and vice versa.  Due to the target independence of P4 the same code can be compiled  for and deployed to the FPGA hardware platform NetFPGA''.  3 years ago   Within the NetFPGA the NAT64 implementation achieves a stable throughput of  9.28 Gigabit/s. Our solution allows in-network translations without a  router or client configurations. Due to the nature of P4, the  implementation runs at line speed and thus with different hardware  the same code can run potentially at much higher speeds,  for instance on 100 Gbit/s switches.  3 years ago   %% P4.
