Flows with DPI stat

[mmanoj]

Dear Team,

I would like to implement DPI functionality to this, can you please guide me which section I have to look at the code.

Dear mmanoj, if you would like to implement DPI, I suggest referring to DPDKStat (http://tstat.polito.it/viewvc/software/tstat/branches/tstat-dpdk/), which is based on DPDK and Tstat. If you prefer to build it based on FloWatcher-DPDK, you could start from here: https://github.com/ztz1989/FloWatcher-DPDK/blob/master/run_to_completion/main.c#L373, this is the point in which packets are retrieved from the NIC, and you might need to integrate DPI libraries into it to achieve high speed. If you have further questions, I am happy to help.

Best regards,
Tianzhu

quick question:

1. How to run this app in 4 core server (syntax)
2. To generate RSS hash is there any specific NIC required or is it support any DPDK compatible NIC ?

Hi, sorry for the late reply.

1, For instructions, please refer to https://github.com/ztz1989/FloWatcher-DPDK#usage-instructions. We have implemented two models, namely run-to-completion and pipeline, you can try either one. It is almost the same as most of the standard DPDK sample applications.
2, For RSS, honestly I am not sure since I have only tried with Intel 82599 NICs. But I do think it should be supported by DPDK compatible NIC.

I'm really happy you're interested in this work. Please let me know if you have more questions. I might not be able to reply promptly these days, but I will for sure reply. 😄

Best regards,
Tianzhu
