3. SPP Primary¶
SPP is originally derived from
Client-Server Multi-process Example
of
Multi-process Sample Application
in DPDK’s sample applications.
spp_primary
is a server process for other secondary processes and
basically working as described in
“How the Application Works” section of the sample application.
However, there are also differences between spp_primary
and
the server process of the sample application.
spp_primary
has no limitation of the number of secondary processes.
It does not work for packet forwaring, but just provide rings and memory pools
for secondary processes.
