|
|
Due to the lack of IPv4 addresses, IPv6 deployements have recently
|
|
gained in importance in the Internet.
|
|
Several transition mechanism exist that allow translating IPv6
|
|
packets into IPv4 packets, thus enabling the coexistence
|
|
and interoperability of both protocols.
|
|
|
|
This thesis describes an implementation of the transition mechanism
|
|
NAT64 implemented in P4. Using the P4 programming language
|
|
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 on the FPGA hardware platform ``NetFPGA''.
|
|
|
|
Within the NetFPGA the NAT64 implementation achieves a stable throughput of
|
|
9.29 Gigabit/s and allows in network translations without a router.
