MoonGen is a fully scriptable high-speed packet generator built on DPDK and LuaJIT. It can saturate a 10 Gbit/s connection with 64 byte packets on a single CPU core while executing user-provided Lua scripts for each packet. Multi-core support allows for even higher rates. It also features precise and accurate timestamping and rate control.
I have followed the directions given in newProtocolTemplate.lua.
I have modifiedgetEthernetPacket() andgetPtpPacket() function in packet.lua so that the createStack() has the appropriate parameters.
After making all these changes I get nan ns readings on running l2-load-latency.lua.
Also when I see packets at the receiving end, they do not have the custom headers that I have created.
Are there any more code changes that I need to make?
Also, does MoonGen support this? Measuring latency for packets with custom headers?
I am trying to adapt
l2-load-latency.luato measure latency for packets that have the following structure:Eth / Custom Header 1 (2 bytes) / Custom Header 2 (10 bytes) / Custom Header 3 (10 bytes) / Custom Header 4 (4 bytes) / Custom Header 5 (4 bytes)I have followed the directions given in
