NAT example is a fully functional NAT (network address translation) program written using NFF-Go framework. It has support for IPv4 and IPv6, ARP, ND, ICMP, ICMPv6, DHCP and DHCPv6 protocols with remote control over GRPC.
To build NAT application you need Go tools. Get them from
Golang site. Go should be 1.11.5 or newer.
First, you need DPDK. Usually NAT application uses DPDK from NFF-Go
framework. If you want to go this way, check out NFF-Go framework from
NFF-Go framework and run make
in it. This will also build DPDK. After that execute source env.sh
script to initialize necessary variables to build native code.
If you have DPDK already built in some other location, change env.sh
script to point RTE_SDK variable to it so that it can set up other
variables correctly and run source env.sh.
To build NFF-Go NAT application use make in this
repository. Alternatively you can run go build or go install ./.... Main executable is nff-go-nat and there is also a GRPC
command line client in client directory.
Testing requires test framework from NFF-Go repository. Test VMs
configurations reside there as well. Test image is built using make images target (removed with make clean-images). Test image can be
deployed with make deploy target (removed from target hosts with
make cleanall). Just like it is done in NFF-Go repository.
It is possible to run stability and performance tests with make test-stability and make test-performance.
Performance testing is done using wrk web server benchmark on one
side and test http server on another side.
