Multi Process Support #277

Open iyerravi opened 6 years ago

iyerravi commented 6 years ago

Hello,

I am looking for multi process support in fstack where in i want to run say 2 Fstack processes and have an ipc (user space) going through them.

So Process A (primary) will rx all packets from nic using fstack and freebsd ip stack and then have an ipc channel(say a pipe) with another fstack process B and give the same packet buffer to the process B. Idea is to avoid copies. I am looking for an infrastructure around this. I know DPDK supports multiple processes and one can have rings between two processes to exchanges buffers. Any pointers around this will be of great help.

Thanks

We are modifying it, but not yet completed, and its performance will be reduced.

Thanks for the update.

infrastructure around this is good , make one process running freebsd ip stack is act like the linux kernel (we call that user space kernel [usk])

other process can use the socket api just as normal api but it communicate with the [usk] process with share memory and rte_ring and no memcpy.

that will be very great if having an infrastructure like this

No completion date.

Now, it can still only be implemented using ff_regist_packet_dispatcher() registration callback function.
