What is your biggest challenge? Is it moving information between cores, or getting information into your application? Consider that most of the multiprocess examples in DPDK do two things: 1) Send/Receive packets to/from a NIC 2) Send packets between cores You obviously want to do #2, and looking at those examples should make how to do it fairly obvious. Is your challenge replacing #1 with something other than a NIC? If so, you *could* consider using a pcap PMD to just read packets from a file. In the past, I have used ring PMDs in conjunction with a secondary process which generates packets to inject arbitrarily formatted packets into my program. > > -- > M at hdi Mor at dm@nd B at die
